Interpretation of Dog Behavior by Children and Young Adults

This study investigates people's ability to interpret dog behavior. Inability to interpret dog behavior correctly may be a factor contributing to young children's higher likelihood of being bitten by dogs. Children (4- to 10-year-olds) and adults (total n = 550) watched videos of dogs displaying friendly, aggressive, and fearful behavior. They were asked to interpret the dogs' behaviors and to describe which features they had attended to in making their decision. Four- and 6-year-old children were unable to identify fearful dogs, while participants in all age groups were capable of identifying friendly and aggressive behavior (p < 0.001). Misinterpretations of fearful behavior were significantly associated with reports of attending to the dog's face rather than other features (χ² = 80.2, df = 1, p < 0.001). Four-year-olds were particularly likely to report looking at the dog's face and together with 6-year-olds they focused more on one feature rather than multiple features in order to make their decisions. The results show that younger children are less good at interpreting dog behavior, and that they are particularly poor at recognizing fear in dogs, while aggression is the most readily recognized behavior. Children's lower ability to interpret dog behavior seems to be due to the features they focus on. Younger children appear to focus on the dogs' most salient features and not the features that would allow them to correctly interpret the dogs' behavior. For example, 4- and 6-year-olds tended to report attending to the fearful dog's face rather than its tail and general posture. The results suggest it would be beneficial to include information about how to interpret dog behavior in dog-bite prevention programs.     

Behavioral Responses of Nursing Home Residents to Visits From a Person with a Dog,a Robot Seal or aToy Cat

Previous studies suggest that contact with dogs can positively affect the wellbeing of elderly people in nursing homes, but there is a lack of research investigating the causal pathways of these effects. One such path- way may relate to the behavioral responses of the elderly when interacting with a dog. The present study compared the immediate behavioral responses of nursing home residents to bi-weekly visits from a person accompanied by either a dog, a robot seal (PARO®), or a soft toy cat, using a randomized controlled design. A total of 100 nursing home residents com- pleted the study. Each participant received a total of 12 visits, during which their behaviors, including interactions between the visitor and the accom- panying animal (real or artificial), were recorded. Also, data on cognitive im- pairment, presence of depressive symptoms, age, time lived in the nursing home, dementia diagnoses, and gender were collected. We found that the immediate responses to, and interaction with, the visiting animal depended on the type of animal that was brought along. The dog and the interactive robot seal triggered the most interaction, in the form of physical contact (F(2,103) = 7.50, p < 0.001), eye contact (F(4,151) = 6.26, p < 0.001), and verbal communication (F(4,195) = 2.87, p < 0.05). As well, the cognitive impairment level of the residents affected with whom they interacted. The higher the cognitive impairment level, the more interaction was directed toward the animal and less toward humans, regardless of visit type (F(2,101) = 4.10, p < 0.05). The dogs and the robot seal stimulated the residents to more in- teraction, compared with the toy cat, but the robot seal failed to maintain the attention at the same level over time. The cognitive functioning of the residents correlated with the level of interaction, and this needs to be studied further.     

Judging a Dog by Its Cover: Morphology but Not Training Influences Visitor Behavior toward Kenneled Dogs at Animal Shelters

Currently, visitor behavior in companion animal shelters is not adequately explored. A sequence of experiments investigated how visitors interacted with kenneled dogs at an animal shelter and whether training dogs to not engage in undesirable behavior in their kennels would evoke more interest from shelter visitors. In a set of two experiments, two sides of an animal shelter were differentially entered into training phases in a multiple baseline design. During the training phase, dogs were trained to not engage in undesirable in-kennel behavior (i.e., to not be in the back of the kennel, to not face backwards, to not lean on kennel walls, and to not bark) through pairing of the visual presentation of the experimenters (experiment 1) and shelter visitors (experiment 2) with treats. Across both experiments, visitors attended to approximately 35% of kenneled dogs and only spent an average of 15 s looking at individual dogs. We found that whereas training was effective in decreasing undesirable behavior in dogs (experiment 1: U = 4.83, p < 0.0001; experiment 2: U = 4.01, p = 0.0001), only morphology influenced visitor behavior. In experiment 1, morphologically preferred dogs (i.e., puppies, long-coated dogs, small dogs, and certain breeds) had a 1.3 times higher frequency of visits to their kennel (F_{(1, 248)} = 5.93, p < 0.05), and in experiment 2, these dogs had a 9 times higher frequency of being taken out of their kennel for further inspection (F_{(1, 69)} = 4.66, p < 0.05), compared to other dogs. One reason for a lack of effect of training may be the relatively small number of visitors observed (n = 115 across both experiments). An alternative reason may be that shelter visitors pay more attention to the morphology rather than the lack of undesirable behavior of kenneled dogs.     

Examining Differences between Homebound Older Adult Pet Owners and Non-pet Owners in Depression,Systemic Inflammation,and Executive Function

Homebound older adults are prone to depression, which is linked to systemic inflammation that promotes executive function decline. A companion animal may reduce the negative biobehavioral processes asso- ciated with depression, inflammation, and reduced executive function in homebound older adults. The primary aim of this study was to examine dif- ferences between homebound older adult pet owners and non-pet owners in depression, salivary C-reactive protein (CRP), and executive function. The secondary aim was to determine if the level of attachment to pets was as- sociated with depression, salivary CRP, and executive function. The study was cross-sectional and investigated homebound older adult pet owners and non-pet owners (n = 88) using psychometrically reliable and valid instru- ments (Geriatric Depression Scale Short Form and CLOX 1). Salivary CRP was assessed with immunoassay. Level of attachment to pets was measured using a Likert scale (0–10). Mean age for the total sample was 75 years (SD = 9). Forty-eight (55%) participants owned pets (56% dogs, 25% cats, 4% other pets, 15% both cats and dogs). Pet owners reported a high level of attachment to pets (Median = 10). Pet owners had significantly higher ex- ecutive function than non-pet owners (t = –2.07; p = 0.04) but there were no significant differences in executive function between cat owners and dog owners (t = 1.53; p = 0.14). Pet owners and non-pet owners were similar in depression (t = –1.80, p = 0.08) and salivary CRP levels (t = 0.27, p = 0.79). Level of attachment to pets was significantly and positively correlated with executive function (r = 0.30; p = 0.04) but was not significantly correlated with depression (r = 0.04, p = 0.77) or salivary CRP (r = –0.04, p = 0.80). Compared with non-pet owners, pet owners had better executive function but similar depression and salivary CRP levels. Reasons for these findings are unclear. Significant positive correlation be- tween pet attachment and executive function suggests further investigation in this area. Future studies with larger samples and a longitudinal design are needed to investigate the biobehavioral changes over time in relation to pet ownership, level of attachment to pets, and executive func- tion in homebound older adults.     

Homelessness and dog ownership: an investigation into animal empathy,attachment, crime,drug use,health and public opinion

Abstract

A sample of 51 homeless people in Cambridge, UK completed a questionnaire featuring adapted Animal Empathy and Companion Animal Bonding Scales. Concepts of crime, drug use, and health matters amongst the homeless, both dog owning and non-dog owning, were investigated, as well. Ninety members of the general public completed a similar questionnaire which sought their opinions on homeless people who own dogs. There was a highly significant difference (p < 0.01) between the homeless and the securely housed on their animal empathy and attachment scores, with the homeless sample displaying higher values. Gender and dog ownership status had no effect on these scores. A near significant result (U = 2, n₁ = 13, n₂ = 58, p = 0.06) was revealed for animal empathy scores of those who gave money to dog-owning homeless people and those who gave to non-dog owning homeless people. Of the public respondents, women were significantly more likely to show concern for a homeless person's dog's welfare than men (X²₍₁₎ = 8.5, p < 0.01), and of the homeless respondents, non-dog owners were significantly more likely than dog owners to believe that having a dog helped initiate conversations with the public (X²₍₁₎ = 4.0, p < 0.05). Highly significant differences (U = 10, n₁ = 31, n₂ = 20, p < 0.01) were found for medical care use between the dog-owning and non-dog owning homeless, and health scores showed a reversed trend compared to that expected for the general population, with dog owners scoring lower than non-dog owners.     

Nonverbal Communication and Human–Dog Interaction

Human–dog interaction relies to a large extent on nonverbal communication, and it is therefore plausible that human sensitivity to nonverbal signals affects interactions between human and dog. Experience with dogs is also likely to influence human–dog interactions, and it has been suggested that it influences human social skills. The present study investigated possible links between human nonverbal sensitivity, experience with dogs, and the quality of human–dog interactions. Two studies are reported. In study 1, 97 veterinary students took a psychometric test assessing human nonverbal sensitivity and answered a questionnaire on their experience with dogs. The data obtained were then used to investigate the relationship between experience with dogs and sensitivity to human nonverbal communication. The results did not indicate that experience with dogs improves human nonverbal sensitivity. In study 2, 16 students with high, and 15 students with low, levels of human nonverbal sensitivity were selected. Each of the 31 students interacted once with an unknown dog in a greeting situation, and these human–dog interactions were videoed. We found that a combined score of dog behaviors relating to insecurity was associated with the students' level of nonverbal sensitivity and experience with dogs: the dog showed more of the insecure behavior when interacting with students with a low level of nonverbal sensitivity and no experience with dogs than it did when interacting with students with a high level of nonverbal sensitivity (irrespective of experience with dogs).     

The Relationship between Empathy,Perception of Pain and Attitudes toward Pets among Norwegian Dog Owners

ABSTRACT

Anthropomorphism, attachment level, and belief in animal mind, as well as owners' level of empathy and attitudes toward their pets, are some of the factors that affect human–animal interactions. Owners' ability to identify painful conditions in their pets may have important consequences for the welfare of these animals. In addition to characterizing the typical Norwegian dog owner, the aim of this work was to study the relationship between empathy, attitudes, and perceived animal pain. A sample of 3,413 dog owners in Norway received an internet-based questionnaire (QuestBack?), to which1896 responded. The questionnaire included four parts: demographics, the Pet Attitude Scale (PAS), the Animal Empathy Scale (AES), and the Pain Assessment Instrument (PAI). For the PAI, participants were presented with 17 photos, showing dogs experiencing painful situations of varying degrees, and were asked to rate the level of pain they believed each animal was enduring, using a Visual Analogue Scale (VAS). Results showed that Norwegian dog owners had very high levels of animal-directed empathy and equally high levels of positive attitudes toward pets. There were differences based on gender, childhood pet keeping, income and education. Differences were also found rooted in owners' use of their dog, whether kept for companionship or hunting, as well as household size, an indication of human social relations. A strong, positive correlation (r = 0.58) was found between animal-directed empathy and positive attitudes toward pets. Empathy was found to be the best predictor of how people rated pain in dogs. The correlations were, however, moderate, indicating that other processes are also involved when observing animals in pain.     

Role of 4-H Dog Programs in Life Skills Development

Stress management, resilience, learning-to-learn, self-esteem, and empathy are life skills that play a pivotal role in the psychosocial development of youth who are prepared to manage everyday challenges, and are caring toward people and animals. We hypothesized that 4-H dog club membership is associated with improved life skills of youth participating in these activities compared with youth who do not. We surveyed Washington and Idaho youth (n = 150, 6–17 years old, M = 11.5) in three conditions: 4-H clubs conducting dog-focused activities (4-H dog clubs), 4-H clubs conducting activities not involving dogs (4-H non-dog clubs), and school youth not involved in 4-H (school group). Life skills, and attitude toward and attachment to pets, were assessed using the Emotional Quotient Inventory: Youth Version (Short), Self-Perception Profile for Children, Social Skills Improvement System Rating Scales, Pet Attitude Scale, and Lexington Attachment to Pets Scale. Analysis of covariance was used to evaluate main effects of condition and covariates (age, sex, number of siblings, and dog(s) at home), and two-way interaction effects on questionnaire scores. Condition affected scores: youth in 4-H dog clubs had higher stress management scores (p < 0.01) compared with those in 4-H non-dog clubs and school group conditions, and higher scholastic competence (p < 0.05) and global self-worth (p < 0.01) scores compared with those in the school group. Much of the variation in scores remains unexplained by the predictors investigated. Thus, the extent to which the results represent an interest in 4-H dog activities due to pre-existing characteristics as opposed to changes resulting from the 4-H experience is unclear. Nevertheless, 83% of study participants had at least one dog, and condition effects were detected after accounting for dogs at home, suggesting that 4-H activities involving dogs had beneficial effects over and above any benefits resulting from dog contact per se.     

DO BLACK-TAILED PRAIRIE DOGS MINIMIZE INBREEDING?

Considerable controversy surrounds the importance of inbreeding in natural populations. The rate of natural inbreeding and the influences of behavioral mechanisms that serve to promote or minimize inbreeding (e.g., philopatry vs. dispersal) are poorly understood. We studied inbreeding and social structuring of a population of black-tailed prairie dogs (Cynomys ludovicianus) to assess the influence of dispersal and mating behavior on patterns of genetic variation. We examined 15 years of data on prairie dogs, including survival and reproduction, social behavior, pedigrees, and allozyme alleles. Pedigrees revealed mean inbreeding coefficients (F) of 1–2%. A breeding-group model that incorporated details of prairie dog behavior and demography was used to estimate values of fixation indices (F-statistics). Model predictions were consistent with the minimization of inbreeding within breeding groups (“coteries,” asymptotic F_IL = –0.18) and random mating within the subpopulation (“colony,” asymptotic F_IS = 0.00). Estimates from pedigrees (mean F_IL = –0.23, mean F_IS = 0.00) and allozyme data (mean F_IL = –0.21, mean F_IS = –0.01) were consistent with predictions of the model. The breeding-group model, pedigrees, and allozyme data showed remarkably congruent results, and indicated strong genetic structuring within the colony (F_LS = 0.16, 0.19, and 0.17, respectively). We concluded that although inbreeding occurred in the colony, the rate of inbreeding was strongly minimized at the level of breeding groups, but not at the subpopulation level. The behavioral mechanisms most important to the minimization of inbreeding appeared to be patterns of male-biased dispersal of both subadults and adults, associated with strong philopatry of females. Incest avoidance also occurred, associated with recognition of close kin via direct social learning within the breeding groups.     

Does Physical Contact with a Dog or Person Affect Performance of a Working Memory Task?

ABSTRACT

Working memory (WM) plays a critical role in the execution of a wide variety of cognitive tasks and predicts academic success. This study was designed to compare the impact of the presence of a dog or a person, and physical contact with them, on the performance of a WM task. It also exam- ined whether the impact differed for two dogs, and whether these factors im- pacted arousal during the WM task. College students (n=31, aged 18–23 years) performed a WM task in five counterbalanced conditions; dog-touch, dog-no-touch, person-touch, person-no-touch, and alone. Participants were randomly assigned to one of two dogs; Miniature Poodle (n=16) or Border Collie (n=15). The WM task involved replicating increasingly complicated se- quences of colored lights by touching them on an iPad^®. Linear mixed model analyses revealed there was a significant interaction between collaborator and touch (p=0.05); best WM scores occurred without touch with either the per- son or the dog present, and worst WM scores occurred when the participant was touching a dog. Analyzing WM test during the dog conditions, touch (p=0.027) and dog breed (p=0.042) contributed independently to it; task completion was worse when the poodle was present and better without touch. Physiological measures [heart rate (HR) and heart rate variability] during the ex- periment indicated that the WM task was physiologically arousing (p<0.001) compared with listening, and HR was higher when touching a person than a dog during the task (p<0.046). These results are consistent with facilitation of performance by the presence of an observer. If there is a beneficial effect on cognition from a dog, physical contact with the dog might not be a necessary component. Aspects of the dog (e.g., breed) are also likely factors in WM task performance. This study highlights the importance of situational characteristics in studies evaluating the impact of companion animals.     

A Longitudinal Study of Decision Making in the Process of Acquiring a Dog

To prevent potential problems in the relationship between people and their dogs, it is important to engage in a thoughtful decision-making process with regard to acquiring a dog. To map the most important elements in the decision-making process, a social cognitive model was applied using seven psychological constructs: perceived advantages of having a dog; perceived disadvantages; the social norm; self-efficacy; optimism; expected commitment; and the intention to acquire a dog. People who were planning to acquire a dog within one year were asked to fill in an online questionnaire and another one 14 months later. The social cognitive constructs were operationalized in the baseline questionnaire, and in the follow-up participants were asked to report whether they had actually acquired a dog during the 14-month interval. The sample (n?=?588) largely consisted of females (88%) and those who had a high level of education (64%). The mean age of the participants was 40.9 years. The data showed significant relations among the decision-making variables, and significant differences between demographic variables related to these. In univariate longitudinal analyses, several social cognitive variables significantly predicted acquiring a dog in the 14-month period. When intention to acquire a dog was entered into the multivariate model, it remained the only predictor (OR = 2.16, p?<?0.001); the model explained 33% of the variance in acquiring a dog. It was possible to assess the main constructs that play a role in decision making regarding acquiring a dog: Most baseline measures were related to actual later behavior, also when taking into account all changes in other internal and external factors that may have taken place. Insight into the decision-making process makes it possible to intervene in it for the good of people, dogs, and their relationships.     

Exploration of Perceptions of Dog Bites among YouTube™ Viewers and Attributions of Blame

Dog bites are a human public health and dog welfare problem. This qualitative study is the first to use YouTube^? to examine how viewers perceive risk of, and attribute blame for, dog bites. Comments underneath 10 videos, chosen to represent a diversity of dog-bite scenarios, were analyzed inductively using thematic analysis. Six themes emerged: 1) Commentators thought that dogs are inherently good-natured but wild animals and emphasized how dogs try to avoid biting people; 2) all recognized breeds of dogs were stereotyped and breed stereotypes were used to shift the blame away from the dog and onto a bite victim, unless the dog identified in a video was a pit bull type. The dog was often blamed in such case; 3) It was argued that a breed limits the extent to which a dog can be trained and controlled; 4) Owners/handlers were often blamed for bites due to their inability to control the dog, and commentators identified the need for appropriate training and socialization in order to control dogs and reduce bite risk; 5) Bite victims were also blamed for the bites when their behavior was perceived as provoking a dog. Although children's behavior was identified as causing a risk, parents of children bitten in the videos were blamed for bites instead due to their approach to child supervision; 6) Bites in a range of contexts, such as play or when viewers thought that the victim's behavior provoked a dog, were seen as well-de-served and normal. It was concluded that although comments on publicly available videos need to be interpreted with caution due to a self-selection bias, their analysis can help to identify attitudes and perceptions towards risk around dogs that could aid bite prevention interventions and policies.     

Acoustic Signals of a Dog and Cat Induce Hemodynamic Responses within the Human Brain

The objective of this study was to evaluate the response of the human frontal cortex when listening to cat meows and dog barks, accompanied with a non-verbal pictorial using an affective rating system that assesses the dimensions of valence and arousal. Each participant (24 students; 12 females and 12 males) sat individually in the middle of a room and listened to the sounds (cat meows, dog barks, and the sound of a train) through ceiling-mounted speakers with a near infrared spectroscopic (NIRS) device. Participants had significantly higher oxygenated hemoglobin (oxy-Hb) levels during the exposure to meows (p < 0.05) and barks (p < 0.01) compared with the train sound. A significant correlation was observed between the dimensions of valence and oxy-Hb activation when the participants listened to cat meows (r = 0.53, p < 0.017; Bonferroni correction). In conclusion, we found that the acoustic signals of companion animals lead to frontal cortex responses in humans, suggesting that their signals have an important function related to their long coexistence with people.     

Living with Wild Dogs: Personality Dimensions in Captive Dingoes (Canis dingo) and Implications for Ownership

Despite the commonly held belief that wild canines do not make “good” household companions, many people choose to live with them. The aim of the present study was to investigate owner-rated personality in a population of dingoes living as companion animals. Owners recruited from a registered dingo organization assessed the personality of 40 dingoes using the Monash Canine Personality Questionnaire- Revised (MCPQ-R). The dingoes (22 female; 18 male) ranged in age from 6 months to 11 years (M = 3.6 years, SD = 2.4); weighed an average of 19.07 kg (SD = 3.41); were mostly entire (i.e., not de-sexed or spayed or neutered; 62.5%) and lived in multiple dingo households (72.5%). Results show that dingoes were rated significantly higher than domestic dogs (n = 455; various breeds from a previous Australian study) for the dimension Motivation/Self-Assuredness (p < 0.001), and significantly lower than dogs for Training Focus (p < 0.001). Many of the personality traits of dingoes reside outside what is considered “ideal” characteristics important for a successful and rewarding dog–owner relationship. It is possible that dingo personality rests within the realms of what is “acceptable” pet canine behavior, at least for some owners, and that they may have adjusted their perception and attitudes to meet their expectations of the species. Motivations for dingo ownership and the applicability of using a domestic dog personality questionnaire on wild canids are discussed.     

Use of Accelerometers to Measure Stress Levels in Shelter Dogs

Stress can compromise welfare in any confined group of nonhuman animals, including those in shelters. However, an objective and practical method for assessing the stress levels of individual dogs housed in a shelter does not exist. Such a method would be useful for monitoring animal welfare and would allow shelters to measure the effectiveness of specific interventions for stress reduction. In this pilot study, activity levels were studied in 13 dogs using accelerometers attached to their collars. Behavioral stress scores as well as urinary and salivary cortisol levels were measured to determine if the dogs' activity levels while confined in the kennel correlated with behavioral and physiological indicators of stress in this population. The results indicated that the accelerometer could be a useful tool to study stress-related activity levels in dogs. Specific findings included a correlation between the salivary cortisol and maximum activity level (r = .62, p = .025) and a correlation between the urine cortisol-to-creatinine ratio and average activity level (r = .61, p = .028) among the study dogs. Further research is needed to better understand the complex relationship between stress and activity level among dogs in a kennel environment.     

What Do Current and Potential Australian Dog Owners Believe about Shelter Practices and Shelter Dogs?

ABSTRACT

Many displaced dogs are unable to find new homes in developed countries, including Australia, each year, even though demand for dogs in general remains high. Understanding community attitudes towards shelter dogs and beliefs about common shelter practices, particularly behavioral assessments conducted by shelters, may help shed light on this issue. To investigate what current and potential dog owners think about shelter dogs, we used an internet-based survey to probe the beliefs and attitudes of 1647 self-selected adult participants, using the online Public Attitudes towards Animal Welfare Shelter-Dogs (PAAWS-D) Survey. Over 80% of the sample indicated they would be likely or very likely to obtain a future pet dog from an animal shelter or rescue organization. Nonetheless, one-third of the participants believed that adult shelter dogs often have behavioral problems. Most participants were aware of routine shelter procedures, such as health and behavioral checks, and the consequences of a dog failing these. Moreover, most participants considered the assessment of shelter dog behavior, using scientific methods, for adoption suitability important. These findings may be used to inform strategies to increase the number of shelter dogs adopted, by clarifying the content of tests used to assess adoption suitability. This could be complemented by daily training and rehabilitation programs to improve shelter dog behavior, increase adoptability, and enhance public perceptions of shelter dogs.     

Interaction with Shelter Dogs Reduces Negative Affect of Adolescents in Substance Use Disorder Treatment

We investigated the effectiveness of a human–animal interaction program, involving dogs from an animal shelter, in improving affect of adolescent males in inpatient treatment for substance use disorder (SUD). We hypothesized that adolescents would experience improvements in affect and attitudes toward activities when participating in human–dog interaction activities (dog-interaction condition) compared with “treatment-as-is” recreational activities (control condition). Participants were assigned to weekly 1-h-long condition activities for 8 weeks (4 weeks per condition). Due to attrition, only the participants’ first and second exposures to each condition were evaluated. Using a withinand between-subjects, repeated measures crossover design, we assessed effects of the two conditions on affective states as indexed by Positive and Negative Affect Scale-Expanded Form (PANAS-X) subscales (mixed linear model, n = 12). Attitudes toward doginteraction and control activities were assessed using a researcher-generated survey (ordered logistic regression, n = 14, mean age = 16.2 years). Condition impacted Hostility (F_(1,31) = 6.55, p < 0.05) and Sadness (F_(1,41) = 4.62, p < 0.05) subscale scores; scores were higher following the control condition and lower following the dog-interaction condition. There was a carryover effect of condition in the previous activity session on Sadness scores during the current activity session (F_(1,41) = 4.32, p < 0.05), suggesting that the prior session experience affected current expectations. In the attitudes survey, the dog-interaction condition elicited more positive responses than the control condition (X² ≥ 4.10, df = 1, p < 0.05). From this exploratory study, we conclude that the dog-interaction activities induced an improvement in affect, specifically within dimensions of negative affect, and participants had a more favorable attitude toward the dog activities than the treatment-as-is activities. Offering activities involving interaction with shelter dogs thus shows promise as a useful method for restoring responsiveness to naturally reinforcing (non-substance-related) affective stimuli in adolescents with SUD.     

Behavior of Walk-Hunters and Pointing Dogs During Northern Bobwhite Hunts

Abstract: Data on the behavior of walk-hunters and pointing dogs aids in understanding and managing quail harvest. We collected Global Positioning System track logs and recorded behaviors of hunters and dogs on northern bobwhite (Colinus virginianus) hunts in Oklahoma (n = 43), Texas (n = 43), and Missouri (n = 7), USA, during the 2005–2006 and 2006–2007 hunting seasons. Hunter velocity averaged 0.8 ± 0.03 (SE) m/second both seasons (n = 85) and pooled (95% CL overlap) velocity of bird dogs was 2.5 ± 0.07 (SE) m/second (n = 154). Hunters spent 60.5 ± 2.4% (SE) of their time walking in 2005–2006 (n = 45) versus 75.2 ± 3.5% (SE) in 2006–2007 (n = 48); respective figures for ranging by dogs were 50.2 ± 2.2% (n = 57) versus 82.0 ± 1.3% (SE; n = 97). Mean duration of a hunt declined from 82.3 ± 8.16 (SE) minutes (n = 45) to 50.2 ± 5.1 (SE) minutes (n = 48) between seasons. Variation in bobwhite abundance was the primary cause of seasonal variation in hunter and dog behaviors because covey-associated activities declined as quail abundance declined. With our results and those of previous workers, managers have first-generation estimates of all variables in hunter-covey interface models for managing bobwhite harvest on discrete areas.     

A Companion Dog Increases Prosocial Behavior in Work Groups

Although organizations use a variety of interventions to improve group functioning, getting people to work effectively with each other remains challenging. Because the presence of a dog has been shown to have positive effects on mood and dyadic interaction, we expected that the presence of a companion dog would also have positive effects on people in work groups. One reason for this is that a companion dog is likely to elevate positive emotions, which often promote prosocial behavior. In study 1 (n = 120) and study 2 (n = 120), participants were randomly assigned to either a dogpresent or dog-absent four-person group. Three friendly companion dogs were randomly assigned to the dog-present groups; only one dog at a time was used during any given experimental session. In study 1, groups worked on an interactive problem-solving task; participants in the dog-present group displayed more verbal cohesion, physical intimacy, and cooperation. Study 2 was identical except that participants worked on a decision-making task requiring less interaction; participants in the dog-present condition displayed more verbal cohesion and physical intimacy and gave higher ratings of trustworthiness to fellow group members. In study 3, we examined behavioral indicators of positive emotions in dog-present and dog-absent groups. Naïve observers (n = 160) rated silent, 40-second video clips of interaction in groups where either a dog was (1) present but not visible or (2) not present. Behavior in dog-present groups was rated as more cooperative, comfortable, friendly, active, enthusiastic, and attentive. We discuss areas for future research and implications of our findings for work and educational settings.
