Modification of instinctive herding dog behavior using reinforcement and punishment

Abstract

“Instinctive” behavior may be modified using operant techniques. We report here on a field study of training herding dogs in which reinforcers and punishers were used by owners, who were themselves being trained to control their dogs. Access to sheep was assumed to be a primary reinforcer for herding dogs. While blocking their access was aversive to them. Over several months, the number of blocking and access actions by the human were scored during the training of seven naïve herding dogs. We found that rates of punishment by blocking the dog's access to sheep or by stopping the dog occurred at higher levels than positive reinforcement from access or verbal praise. While positive reinforcement can be used exclusively for the training of certain behaviors, it is suggested that in the context of instinctive motor patterns, negative reinforcement and punishment may be desirable and necessary additions to positive reinforcement techniques.     

What’s in a Name? Effect of Breed Perceptions & Labeling on Attractiveness,Adoptions & Length of Stay for Pit-Bull-Type Dogs

Previous research has indicated that certain breeds of dogs stay longer in shelters than others. However, exactly how breed perception and identification influences potential adopters'' decisions remains unclear. Current dog breed identification practices in animal shelters are often based upon information supplied by the relinquishing owner, or staff determination based on the dog''s phenotype. However, discrepancies have been found between breed identification as typically assessed by welfare agencies and the outcome of DNA analysis. In Study 1, the perceived behavioral and adoptability characteristics of a pit-bull-type dog were compared with those of a Labrador Retriever and Border Collie. How the addition of a human handler influenced those perceptions was also assessed. In Study 2, lengths of stay and perceived attractiveness of dogs that were labeled as pit bull breeds were compared to dogs that were phenotypically similar but were labeled as another breed at an animal shelter. The latter dogs were called "lookalikes." In Study 3, we compared perceived attractiveness in video recordings of pit-bull-type dogs and lookalikes with and without breed labels. Lastly, data from an animal shelter that ceased applying breed labeling on kennels were analyzed, and lengths of stay and outcomes for all dog breeds, including pit bulls, before and after the change in labeling practice were compared. In total, these findings suggest that breed labeling influences potential adopters'' perceptions and decision-making. Given the inherent complexity of breed assignment based on morphology coupled with negative breed perceptions, removing breed labels is a relatively low-cost strategy that will likely improve outcomes for dogs in animal shelters.     

Behavioral and Self-report Measures Influencing Children's Reported Attachment to Their Dog

Despite the prevalence of dogs as family pets and increased scientific interest in canine behavior, few studies have investigated charac- teristics of the child or dog that influence the child–dog relationship. In the present study, we explored how behavioral and some self-report measures influence a child's reported attachment to their dog, as assessed by the Lexington Attachment to Pets Scale (LAPS). We tested specifically whether children (n = 99; mean age = 10.25 years, SD = 1.31) reported stronger attachment to dogs that were perceived as being more supportive (mea- sured by a modified version of the Network of Relationships Inventory), that were more successful in following the child's pointing gesture in a standard two-object choice test, or that solicited more petting in a sociability assess- ment. In addition, we assessed whether children's attachment security to their parent and being responsible for the care of their dog influenced re- ported attachment to the dog. Overall, perceived support provided by the dog was highly predictive of all subscales of the LAPS. The dog's success in following the child's pointing gestures and lower rates of petting during the sociability assessment were associated with higher ratings on the General Attachment subscale of the LAPS, but not on the other subscales. Caring for the dog did not predict the child's reported attachment to the dog, but did predict the dog's behavior on the point-following task and petting during the sociability task. If the child cared for the dog, the dog was more likely to be successful on the pointing task and more likely to be petted. These results indicate a dyadic relationship in which the child's care for the dog is associ- ated with the dog's behavior on the behavioral tasks, which in turn is related to the child's reported attachment to their dog. The direction of influence and nature of this dyad will be a fruitful area for future research.     

The Coldest Dog and Pony Show on Earth: Animal Welfare on the First Expeditions to Reach the South Pole

ABSTRACT

The expeditions to reach the South Pole mounted by Scott, Amundsen, and others between 1901 and 1912 have attracted considerable scholarly effort. These expeditions all took draught animals, which were key to the success or failure of the missions. Much of the literature in this field is highly partisan, focusing on the relative merits of Scott and Amundsen: the fates of their animals have received little attention except as ammunition for one side or another of this very polarized discourse. This paper describes the treatment of the dogs and ponies taken as draught animals on the expeditions led by Scott and Amundsen. These expeditions were planned such that animals would be used to pull sledges and slaughtered when required for food, or when the food for the animals ran out. Each of these expeditions is shown to have engaged in cruel practices and to have caused some animals extreme suffering. Scott's and Amundsen's management of their animals are compared. Amundsen kept close oversight of the care of the animals whereas Scott tended to delegate, with the results that on occasions Scott's animals did not receive timely attention and suffered as a result. Scott had reservations about using dogs because he viewed them mainly as intelligent companion animals. He had difficulties viewing dogs as working animals that might suffer, or as potential food, but no apparent reservations about using ponies in such ways. Amundsen's attitudes towards the dogs on his expedition and the animals' welfare outcomes are closely examined in this paper in the light of previous contentions that Amundsen was a serial animal abuser. While Amundsen also saw dogs as companions, he viewed them as draught animals and/or food sources as he felt his circumstances warranted. It is shown that outrage at the fates of Amundsen's dogs rests within past hagiographic endeavors in addition to modern western beliefs that dogs are pets, not draught animals; and from Western attitudes towards the consumption of dog flesh.     

Adopting shelter dogs: Owner experiences of the first month post-adoption

Abstract

A number of studies have examined factors associated with the relinquishment of pet dogs to animal welfare shelters. In Australia, however, there has been little investigation of new owners' experiences when they subsequently adopt one of these dogs. To address this, telephone interviews were conducted with 62 persons who had recently adopted a shelter dog in Melbourne, Australia. Data relating to adopter demographics, factors influencing the selection of a dog and problems experienced post-adoption were collected. Shelter dogs were primarily acquired to replace a deceased pet or as companions to humans or other dogs. Selection was influenced by the dog's size, general appearance and behavior, with adopters preferring dogs who behaved in a calm and friendly manner. Common problems reported during the initial post-adoptive period were hyperactivity/boisterousness, compatibility issues with an existing pet and pulling on the lead. Escaping was strongly associated with separation-related problems. Three-quarters of the sample walked their dogs daily for 30 minutes or more, with larger dogs exercised for longer. Most dogs were exercised off-lead for some period, particularly larger dogs. This study indicates that improving assessment and matching procedures, and providing in-house and post-adoptive training could increase rehoming success rates.     

The Relationship between Personality Match and Pet Satisfaction among Dog Owners

ABSTRACT

We investigated the extent to which personality match between dog and owner is related to pet satisfaction. Prior research shows that owners relinquish dogs at a high rate, not only in the United States, but also in other countries. New procedures to match owners to future pets could reduce the problem of homeless pets. These were developed after examining the literature to determine all possible traits in dogs and conducting structured interviews to check for further traits. After doing this, 45 traits were determined, and two surveys were created. One survey assessed the personality traits of the dog, and the other assessed the owner's personality traits. In our study, 88 dog owners were asked to report their satisfaction with their self-selected dog and to describe their dog's personality characteristics, based on eight dimensions. Correlations between dog satisfaction scores and dog–owner personality match revealed four characteristics that were significantly associated with satisfaction: tendency to share possessions, love of running outside, likeliness of being destructive, and ability to get along with others. These results suggest that prospective dog owners may want to consider adopting dogs who match their personality on these characteristics. Matching the personality of dogs and their owners on a few characteristics may predict owner satisfaction. This is important as it may reduce the number of dogs that are relinquished by owners as well as the number of dogs left homeless each year.     

Dogs that bite.

OBJECTIVE--To study the circumstances of dog bites and identify risk factors. DESIGN--Postal questionnaire survey and case note review of victims of dog bites referred between 1982 and 1989. SETTING--One referral based regional plastic surgery unit. PATIENTS--146 consecutive patients referred for primary treatment of dog bites, for whom current addresses were available for 133, 107 (81%) of whom returned the questionnaire. RESULTS--The male to female ratio was 74:72; 79 (54%) patients were aged below 15 years. The commonest dogs producing bites were Staffordshire bull terriers (15 cases), Jack Russell terriers (13), medium sized mongrels (10), and Alsatians (nine). 82 of 96 (85%) dogs were male. 29 of 47 (62%) adults were bitten at home and 45 of 60 (75%) children at a friend''s, neighbour''s, or relative''s house. 91 of 107 (85%) bites occurred in the dog''s home. Bites occurred during playing with 13 (12%), petting 14 (13%), or waking 16 (15%) dogs. 45 (42%) bites were judged as unprovoked. 32 bites were identified as severe and 11 attacks as sustained. CONCLUSIONS--Most victims are bitten by male dogs which they either own or have had frequent contact with, and the bite occurs in the dog''s home.     

Attendance and non-attendance for breast screening at the south east London breast screening service.

OBJECTIVES--To ascertain the reasons for a low rate of response for breast screening. DESIGN--All relevant aspects of the organisational process examined, including general practitioners'' notes. Non-responders visited and interviewed. SETTING--An inner city breast screening service working on the model advocated by the Forrest report. SUBJECTS--288 Women aged 50-64 registered with several general practices and invited for screening by post. MAIN OUTCOME--Determination of factors important for success of breast screening programmes. RESULTS--After five women were excluded by their general practitioners the response rate was 129 out of 283 (46%), but 99 (35%) of the women did not receive their invitations because of inaccuracies in the family practitioner committee''s database and general practitioners failing to check women''s addresses completely. CONCLUSIONS--Increased rates of response will depend on enabling general practitioners to check addresses and on an increased awareness of the importance of information.     

Two Sides of the City: Dog-keeping Practices in Russian Urban Areas

This article examines dog–owner relations and dog ownership in Omsk, Russia. We describe typical dog-keeping practices and reveal how diverse urban environments can influence these practices. A two-stage survey was conducted in 2014 to determine the numbers and management of dogs owned. In total, some 1,583 households at the first stage of the research and 323 households at the second stage were interviewed face-to-face. About 23% of all households in Omsk owned dogs, but this proportion varied markedly for different parts of the city. In the city's single-story area, 71.5% of households had dogs, while in the multi-story area this was only 10.8%. Dog-keeping practices were different in these areas. Significant differences in these practices were shown for almost all aspects: the selection criteria, dog feeding, veterinary treatment, dog walking, the roles of dogs, and owners’ attitudes toward them. Owners living in the single-story area demonstrated a utilitarian or functional approach to their dogs—influencing the sex, size, and the breed of the animal. Dogs often lived outside the house; they were vaccinated and taken to the veterinarian less often than dogs from the multi-story area. The owners in the multi-story area described more affectionate feelings toward their dogs. This is reflected in both the choice and treatment of the animals. We observed a larger proportion of pedigree dogs, a larger proportion of female animals, more vaccinations, and the owners making a variety of purchases for their dogs.     

When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs (Canis lupus familiaris) compared with wolves (Canis lupus)

Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist on such tasks. While dogs'' ‘looking back’ behaviour has been used as an example of socio-cognitive advancement, an alternative explanation is that pet dogs show less persistence on independent tasks more generally. In this study, pet dogs, shelter dogs and wolves were given up to three opportunities to open a solvable puzzle box: when subjects were with a neutral human caretaker, alone and when encouraged by the human. Wolves were more persistent and more successful on this task than dogs, with 80% average success rate for wolves versus a 5% average success rate for dogs in both the human-in and alone conditions. Dogs showed increased contact with the puzzle box during the encouragement condition, but only a moderate increase in problem-solving success. Social sensitivity appears to play an important role in pet and shelter dogs'' willingness to engage in problem-solving behaviour, which could suggest generalized dependence on, or deference to, human action.     

Why Do People Laugh during Dog–Human Play Interactions?

Given that human laughter has been posited to signal playfulness to dogs, nonserious social incongruity, and positive affect, laughter should occur during incongruous contexts in an affectively positive, nonserious social activity such as dog–human play. A total of 116 laughs in relation to dogs were discerned on videotapes of 46 dog–human play interactions in the US, 23 with familiar and 23 with unfamiliar pairs. Laughter occurred during 61% of interactions, and always expressed positive affect. Contexts in which laughter occurred (in decreasing frequency) were failure of the dog during play, or to play at all or as the person wanted; exaggerated or unexpected engagement by the dog; excretion; unexpected success by the dog in obtaining an object; and, once, threat from the dog. Laughter never induced play, and usually occurred when a dog was not playing. Women laughed more than men, especially for a male audience when playing with their own dog. In all contexts, participants experienced incongruous events; contexts were nonserious, except for the dog's threat, where laughter signaled friendliness. These data are largely consistent with laughter signaling positive affect and awareness of (usually nonserious) social incongruity, and inconsistent with laughter signaling playfulness to dogs.     

Genetic and environmental factors affecting the suitability of dogs as Guide Dogs for the Blind

Summary Many dogs are found to be unsuitable for training as guide dogs for the blind. Consequently the Royal Guide Dogs for the Blind Association of Australia has embarked on a breeding program to produce a strain of labrador dogs which is suitable for guide dog training.The most common reasons for rejecting dogs are fearfulness, dog distraction, excitability, health and physical reasons and hip dysplasia. The selection program seems to have been successful in improving the success rate mainly by lowering fearfulness, but there has not been a continuing improvement. This is probably due to continual introduction of dogs from other populations into the breeding program.Males suffer from a higher rejection rate due to dog distraction and a lower rejection rate due to fearfulness and excitability than females, so that there is little sex difference in overall success rate.The heritability of success (0.44) is high enough to predict further progress from selection, again mainly against fearfulness.Variation in environment prior to 6 weeks of age, in age when dogs were placed into a private home and in age when males were castrated, had little effect on the success rate.     

Community-Based Control of the Brown Dog Tick in a Region with High Rates of Rocky Mountain Spotted Fever, 2012–2013

Rocky Mountain spotted fever (RMSF) transmitted by the brown dog tick (Rhipicephalus sanguineus sensu lato) has emerged as a significant public health risk on American Indian reservations in eastern Arizona. During 2003–2012, more than 250 RMSF cases and 19 deaths were documented among Arizona''s American Indian population. The high case fatality rate makes community-level interventions aimed at rapid and sustained reduction of ticks urgent. Beginning in 2012, a two year pilot integrated tick prevention campaign called the RMSF Rodeo was launched in a ∼600-home tribal community with high rates of RMSF. During year one, long-acting tick collars were placed on all dogs in the community, environmental acaricides were applied to yards monthly, and animal care practices such as spay and neuter and proper tethering procedures were encouraged. Tick levels, indicated by visible inspection of dogs, tick traps and homeowner reports were used to monitor tick presence and evaluate the efficacy of interventions throughout the project. By the end of year one, <1% of dogs in the RMSF Rodeo community had visible tick infestations five months after the project was started, compared to 64% of dogs in Non-Rodeo communities, and environmental tick levels were reduced below detectable levels. The second year of the project focused on use of the long-acting collar alone and achieved sustained tick control with fewer than 3% of dogs in the RMSF Rodeo community with visible tick infestations by the end of the second year. Homeowner reports of tick activity in the domestic and peridomestic setting showed similar decreases in tick activity compared to the non-project communities. Expansion of this successful project to other areas with Rhipicephalus-transmitted RMSF has the potential to reduce brown dog tick infestations and save human lives.     

Diurnal Human Activity and Introduced Species Affect Occurrence of Carnivores in a Human-Dominated Landscape

Diurnal human activity and domestic dogs in agro-forestry mosaics should theoretically modify the diurnal habitat use patterns of native carnivores, with these effects being scale-dependent. We combined intensive camera trapping data with Bayesian occurrence probability models to evaluate both diurnal and nocturnal patterns of space use by carnivores in a mosaic of land-use types in southern Chile. A total of eight carnivores species were recorded, including human-introduced dogs. During the day the most frequently detected species were the culpeo fox and the cougar. Conversely, during the night, the kodkod and chilla fox were the most detected species. The best supported models showed that native carnivores responded differently to landscape attributes and dogs depending on both the time of day as well as the spatial scale of landscape attributes. The positive effect of native forest cover at 250m and 500 m radius buffers was stronger during the night for the Darwin''s fox and cougar. Road density at 250m scale negatively affected the diurnal occurrence of Darwin´s fox, whereas at 500m scale roads had a stronger negative effect on the diurnal occurrence of Darwin´s foxes and cougars. A positive effect of road density on dog occurrence was evidenced during both night and day. Patch size had a positive effect on cougar occurrence during night whereas it affected negatively the occurrence of culpeo foxes and skunks during day. Dog occurrence had a negative effect on Darwin''s fox occurrence during day-time and night-time, whereas its negative effect on the occurrence of cougar was evidenced only during day-time. Carnivore occurrences were not influenced by the proximity to a conservation area. Our results provided support for the hypothesis that diurnal changes to carnivore occurrence were associated with human and dog activity. Landscape planning in our study area should be focused in reducing both the levels of diurnal human activity in native forest remnants and the dispersion rates of dogs into these habitats.     

Effects of Sex and Reproductive State on Interactions between Free-Roaming Domestic Dogs

Free-roaming dogs (Canis familiaris) are common worldwide, often maintaining diseases of domestic pets and wildlife. Management of these dogs is difficult and often involves capture, treatment, neutering and release. Information on the effects of sex and reproductive state on intraspecific contacts and disease transmission is currently lacking, but is vital to improving strategic management of their populations. We assessed the effects of sex and reproductive state on short-term activity patterns and contact rates of free-roaming dogs living in an Australian Indigenous community. Population, social group sizes and rates of contact were estimated from structured observations along walked transects. Simultaneously, GPS telemetry collars were used to track dogs'' movements and to quantify the frequency of contacts between individual animals. We estimated that the community''s dog population was 326±52, with only 9.8±2.5% confined to a house yard. Short-term activity ranges of dogs varied from 9.2 to 133.7 ha, with males ranging over significantly larger areas than females. Contacts between two or more dogs occurred frequently, with entire females and neutered males accumulating significantly more contacts than spayed females or entire males. This indicates that sex and reproductive status are potentially important to epidemiology, but the effect of these differential contact rates on disease transmission requires further investigation. The observed combination of unrestrained dogs and high contact rates suggest that contagious disease would likely spread rapidly through the population. Pro-active management of dog populations and targeted education programs could help reduce the risks associated with disease spread.     

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.     

Dog Breed Stereotype and Exposure to Negative Behavior: Effects on Perceptions of Adoptability

The purpose of the study was to determine if brief exposure to a dog behaving badly or in a friendly manner affects subsequent perceptions of the target dog's and other dogs' adoptability. Participants viewed a videotape of an adoptable German shepherd behaving either aggressively or prosocially and were then asked to rate the characteristics and adoptability of the same and different dogs. The results showed that people who saw the aggressive behavioral schema perceived only the target dog and a dog of the same breed to be significantly less adoptable than dogs of other breeds (p < .01). Results of a principal components analysis showed participants perceived the adoptability of dogs to be related to “sociability”: Adoptable dogs were more approachable, friendly, intelligent, and less dangerous and aggressive (p < .01). Brief exposure to a misbehaving dog prior to making a decision to adopt may unfairly penalize other dogs perceived to be similar to the misbehaving dog.     

The epidemiology of dog bite injuries in Switzerland – characteristics of victims,biting dogs and circumstances

Abstract

Dogs are a potential source of several health hazards for humans. Public attention has recently focussed on dog bites, and different prevention strategies have been suggested. As few data on dog bite epidemiology are available, a prospective study was conducted in family practices (FP) and emergency departments (ED) in Switzerland. The objectives of this study were to estimate the incidence of dog bites receiving medical treatment and to identify possible risk factors. An annual dog bite incidence rate of 180/100 000 population was estimated. The highest incidence rates were found in children, young adults and dog owners. While head and neck injuries were most common (37% of FP and 45% of ED cases) amongst children and these tended to have more severe sequelae, adults' injuries most commonly involved the extremities. Victim–dog interactions prior to the incident often were observed in children, particularly in infants (82% of 0–4-year-old cases) and in family dog bites (88%). Biting dogs were most commonly medium or large in size, male, and aged < 5 years. The three most popular breeds (Shepherd, Retriever Dogs and Swiss Mountain Breeds) also were the three most common biters. However, Shepherd dogs and Rottweilers were more common among biting dogs. No difference in bite risk was found between pure-bred and cross-bred dogs. Results of this study suggest that dog bites are a common event in the community. A multifactorial approach to dog bite prevention is recommended.     

Personality Consistency in Dogs: A Meta-Analysis

Personality, or consistent individual differences in behavior, is well established in studies of dogs. Such consistency implies predictability of behavior, but some recent research suggests that predictability cannot be assumed. In addition, anecdotally, many dog experts believe that ‘puppy tests’ measuring behavior during the first year of a dog''s life are not accurate indicators of subsequent adult behavior. Personality consistency in dogs is an important aspect of human-dog relationships (e.g., when selecting dogs suitable for substance-detection work or placement in a family). Here we perform the first comprehensive meta-analysis of studies reporting estimates of temporal consistency of dog personality. A thorough literature search identified 31 studies suitable for inclusion in our meta-analysis. Overall, we found evidence to suggest substantial consistency (r = 0.43). Furthermore, personality consistency was higher in older dogs, when behavioral assessment intervals were shorter, and when the measurement tool was exactly the same in both assessments. In puppies, aggression and submissiveness were the most consistent dimensions, while responsiveness to training, fearfulness, and sociability were the least consistent dimensions. In adult dogs, there were no dimension-based differences in consistency. There was no difference in personality consistency in dogs tested first as puppies and later as adults (e.g., ‘puppy tests’) versus dogs tested first as puppies and later again as puppies. Finally, there were no differences in consistency between working versus non-working dogs, between behavioral codings versus behavioral ratings, and between aggregate versus single measures. Implications for theory, practice, and future research are discussed.     

Is That Dog a Pit Bull? A Cross-Country Comparison of Perceptions of Shelter Workers Regarding Breed Identification

Bull breeds are commonly kept as companion animals, but the pit bull terrier is restricted by breed-specific legislation (BSL) in parts of the United States and throughout the United Kingdom. Shelter workers must decide which breed(s) a dog is. This decision may influence the dog's fate, particularly in places with BSL. In this study, shelter workers in the United States and United Kingdom were shown pictures of 20 dogs and were asked what breed each dog was, how they determined each dog's breed, whether each dog was a pit bull, and what they expected the fate of each dog to be. There was much variation in responses both between and within the United States and United Kingdom. UK participants frequently labeled dogs commonly considered by U.S. participants to be pit bulls as Staffordshire bull terriers. UK participants were more likely to say their shelters would euthanize dogs deemed to be pit bulls. Most participants noted using dogs' physical features to determine breed, and 41% affected by BSL indicated they would knowingly mislabel a dog of a restricted breed, presumably to increase the dog's adoption chances.
