The Use of Positive Reinforcement in Training Zebra Sharks (Stegostoma fasciatum)

Few studies have examined how personality traits may be related to the amounts and types of attachments humans have toward companion animals (pets). In this study, 1,098 companion animal guardians (owners) completed a survey that included the Big Five Inventory, the Lexington Attachment to Pets Scale, and the Pet Attachment Questionnaire. Each participant chose whether he or she identified as a Cat Person, Dog Person, Both, or Neither. Results indicated that neuroticism, conscientiousness, choosing a dog as a favorite pet, and identifying as a Cat Person, Dog Person, or Both predicted affection for a pet. Conscientiousness, extraversion, and openness decreased avoidant attachment to pets, and neuroticism increased anxious attachment to pets. Both dogs and cats could benefit from pet owners who are conscientious, and there may be some benefits of neuroticism in pet owners. The findings of this study will advance understanding of the human–animal bond. As this understanding increases, measurements of human attachment and personality may be useful for the development of tools that could assist shelter employees and veterinarians in counseling people about pet ownership.     

Tackling aquatic invasions: risks and opportunities for the aquarium fish industry

The aquarium trade is an important and rapidly growing vector for introduced species in the United States. We examined this vector by surveying pet stores in the San Francisco Bay–Delta region to compile a list of aquarium fish species commonly stocked. We identified which of these species might be able to survive in the Bay–Delta, and investigated store representatives’ knowledge and attitudes about biological invasions. A restrictive analysis using conservative estimates of fish temperature tolerances and environmental conditions found that the local aquarium trade includes 5 fish species that can survive in a temperate system such as the Bay–Delta. Under more inclusive parameters, up to 27 fish species met the criteria for survival in the Bay–Delta. We further explored these results by comparing potential invader incidence between different types of stores. In the more restrictive analysis, three national retail chains stocked significantly more potentially invasive species than independent aquarium stores, but there was no difference in the more inclusive analysis. A significantly higher percentage of fish taxa were easily identifiable and well-labeled in chain stores than in independent stores. Most aquarium store representatives indicated willingness to take action to reduce the threat of trade-related introductions, although chain store employees were more willing to assign responsibility for reducing this threat to the aquarium industry than were independent store employees. Management efforts for this vector should focus on (a) improving labeling and identification of fish species in stores, (b) expanding the often spotty data on fish physiological tolerances, especially for saltwater species, (c) educating customers and store employees about the risks posed by pet release, and (d) providing better options for responsible disposal of unwanted fish.

A Survey of Companion-Animal Owners Affected by the East Japan Great Earthquake in Iwate and Fukushima Prefectures,Japan

ABSTRACT

The unprecedented East Japan Great Earthquake in March 2011 impacted many humans as well as animals. To date, only national surveys that do not necessarily focus on the heavily impacted areas have been administered, and there is a lack of data on the situation for companion animals and their owners in these areas. This survey was administered between June and November 2012 to pet owners in Iwate (n = 140) and Fukushima (n = 149) Prefectures in north-eastern Japan, areas heavily affected by the disaster. It explored the types of disaster preparations for pets engaged in by owners; the situation on evacuation with pets; the use of, and need for, pet-related support after the disaster; and the associations between pet attachment and disaster-related behaviors of pet owners. In total, 41.2% (n = 119) of all respondents were able to evacuate with their pets, and evacuation rates were especially low in Fukushima. With the exception of preparation of pet food and other supplies, less than 50% of respondents engaged in different types of pet-related disaster preparations. Especially in Fukushima, those who evacuated with their pets were better prepared compared with those who could not. The rate of utilization of support was also low, with less than 50% of respondents utilizing each type of support, regardless of pet-evacuation status and area. The need for support was generally higher during the initial phase (immediately after the disaster; 30–40%) compared with the current phase (20–30%). However, in Fukushima the difference between the initial and current phases was not significant for both those who evacuated with their pets and those who could not. Bivariate analyses indicated mixed results for the association between disaster-related behaviors and pet attachment. Implications for future disaster-prevention measures are discussed.     

Stored-product insects associated with a retail pet store chain in Kansas

The types and numbers of insect species associated with eight Kansas retail stores belonging to a pet store chain were surveyed during February to August 2001. Insects were monitored at 1-3-wk intervals using food- and pheromone-baited pitfall traps for beetles and pheromone-baited sticky traps for moths. Thirty traps of each type were placed within a store. Thirty insect species belonging to 20 families in four orders were recorded from the eight stores. The weevils, Sitophilus spp.; Indianmeal moth, Plodia interpunctella (Hübner); and merchant grain beetle, Oryzaephilus mercator (Fauvel), were the most common and abundant species in all stores, whereas the red-legged ham beetle, Necrobia rufipes (Degeer), and red flour beetle, Tribolium castaneum (Herbst), were abundant only in one store. The numbers of each insect species captured varied from store to store. In each of the stores, a total of 12-19 stored-product species were captured in traps, and seven of the eight stores had relatively high species diversity. With the exception of one store, the different types of insect species found among the remaining seven stores were essentially similar. The mean density of insects in infested bulk-stored and bagged pet food products removed from a store ranged from 65 to 656 adults/kg. The types and numbers of insect species captured in traps indicated that infestations were well established in the surveyed stores. Early detection and management of these infestations is critical for maintaining quality and integrity of food products sold in the pet stores.     

Laughing Rats Are Optimistic

Emotions can bias human decisions- for example depressed or anxious people tend to make pessimistic judgements while those in positive affective states are often more optimistic. Several studies have reported that affect contingent judgement biases can also be produced in animals. The animals, however, cannot self-report; therefore, the valence of their emotions, to date, could only be assumed. Here we present the results of an experiment where the affect-contingent judgement bias has been produced by objectively measured positive emotions. We trained rats in operant Skinner boxes to press one lever in response to one tone to receive a food reward and to press another lever in response to a different tone to avoid punishment by electric foot shock. After attaining a stable level of discrimination performance, the animals were subjected to either handling or playful, experimenter-administered manual stimulation – tickling. This procedure has been confirmed to induce a positive affective state in rats, and the 50-kHz ultrasonic vocalisations (rat laughter) emitted by animals in response to tickling have been postulated to index positive emotions akin to human joy. During the tickling and handling sessions, the numbers of emitted high-frequency 50-kHz calls were scored. Immediately after tickling or handling, the animals were tested for their responses to a tone of intermediate frequency, and the pattern of their responses to this ambiguous cue was taken as an indicator of the animals'' optimism. Our findings indicate that tickling induced positive emotions which are directly indexed in rats by laughter, can make animals more optimistic. We demonstrate for the first time a link between the directly measured positive affective state and decision making under uncertainty in an animal model. We also introduce innovative tandem-approach for studying emotional-cognitive interplay in animals, which may be of great value for understanding the emotional-cognitive changes associated with mood disorders.     

The Association of Pet Ownership and Attachment with Perceived Stress among Chinese Adults

Pet ownership is associated with both positive and negative emotions. Given that not everyone responds to pet care in a stressful way, perceptions of companion animals may play a role in how owners respond to them. In this study, we explored the relationship between pet ownership and perceived stress among Chinese pet owners. We also examined the effect of care practices and perceptions of pets on perceived stress. A total of 288 Hong Kong Chinese, adult pet owners, aged 18 to 70 years, were recruited. Participants were surveyed using a self-administered questionnaire covering demographics, pet ownership background, pet attachment, and perceived stress. Regression analyses were performed to examine pet attachment in different demographic groups and its relationship with perceived stress. Moderation and mediation analyses were performed to elucidate their underlying mechanisms. After adjusting for demographics and pet ownership background, greater attachment to a pet was associated with lower stress in owners. The perception of pets as family members minimized the stressful burden of pet care. More time spent caring for a pet increased attachment to that animal which in turn reduced stress in owners. The findings suggest attachment to companion animals and the perception of them as family members can help manage and reduce stress in owners.     

Psychological Mechanisms Predicting Wellbeing in Pet Owners: Rogers’ Core Conditions versus Bowlby’s Attachment

While pet ownership may confer physical and psychological health benefits, existing research presents inconsistent findings, and the psychological mechanisms through which health benefits might be conferred are unknown. Exploring human–pet relationships from the perspectives of Bowlby’s attachment theory, namely “attachment-related anxiety” and “attachment-related avoidance,” and Rogers’ core conditions including “unconditional positive regard” and “empathy” may highlight the psychological mechanisms involved. This study compared quality of life (QOL) and psychopathology in pet owners with those without pets. In the pet owners, we additionally assessed pet attachment, and perceived empathy, unconditionality, and congruence in the human–pet relationships. We then compared the relative value of Bowlby’s attachment versus Rogers’ core conditions in human– pet relationships as predictors of wellbeing in pet owners. Overall, pet owners and non-pet owners did not significantly differ in terms of QOL or psychopathology. However, in pet owners, secure pet attachments were associated with lower psychological distress and psychopathology, and those perceiving higher levels of Rogers’ core conditions from their pets had higher QOL. Bowlby’s pet attachment insecurity predicted psychological distress and psychopathology, while Rogers’ total core conditions in pets were significantly predictive of QOL of owners. Differences in wellbeing may not be reliably discernable between pet owners and non-pet owners, as wellbeing is related not to pet ownership alone but to qualities of individual human–pet relationships. The results provide new information about psychological mechanisms through which human–pet interactions are conferred, and support for the applicability of both Bowlby’s and Rogers’ concepts.     

Using Attachment Theory and Social Support Theory to Examine and Measure Pets as Sources of Social Support and Attachment Figures

Companion animals are increasingly being recognized by society as beneficial to our health and considered by many owners as authentic and affectional family members. Human relationship theories help us to understand the emotional and supportive aspect of the human– companion animal bond. This study uses attachment theory, social support theory, and the concept of the hierarchical nature of attachment relationships to further understand and measure human–animal attachment. In study 1,161 university-student pet owners completed a modified multidimensional scale of perceived social support (MSPSS) that included pets as a source of support, and we pre-tested a 60-item pet attachment measure. Results showed that students perceived their pets as distinctive sources of social support, at similar levels to their significant others, family, and friends. Principal components analysis of the 60-item measure reduced it to 31 items, and revealed four pet attachment components: (a) Proximity maintenance and interaction, (b) Emotional attachment behaviors, (c) Emotional support given and received, and (d) Emotional and monetary value. The scale was named the Emotional and Supportive Attachment to Companion Animals Scale (ESACA) (Cronbach’s α = 0.96). In study 2, 83 university students completed an attachment hierarchy scale and the ESACA. Companion animals were included in pet owners’ attachment hierarchies and ranked higher than siblings but lower than romantic partners, parents, and close friends. Those who indicated higher attachment to their companion animals ranked them higher in their attachment hierarchy than those less attached. This study supports and extends previous research that has used aspects of attachment theory and social support theory when exploring the human–animal bond. Many companion animal owners perceive their pets as additional sources of emotional support, fulfilling the four features of an attachment relationship and including them in their hierarchy of important attachment relationships.     

Attitudes and Motivations of Owners Who Enroll Pets in Pet Life-Care Centers

The purpose of this study was to examine the characteristics, motivations, and expectations of humans who enroll their dogs, cats, and other pets into pet life-care centers. Pet life-care centers are groups or institutions that provide a permanent home for pets in the event of the owner’s illness, inability to care for their pet, or death. The long-term pet care industry has grown in the quality and type of care available to pet owners and is a classic example of the human–animal bond in action. This bond is well-documented in the literature, with most research focusing on physical, emotional, and mental health benefits to the pet owner. Few studies have examined how the human–animal bond affects the animal, and little is known about the motives and expectations of owners who enroll their pet in a life-care center. We conducted a study using a mail questionnaire sent to 163 current clients of a pet life-care center in Texas, USA. Of 101 respondents, whose ages ranged from 30 to over 70, most were female, married, and college-educated. Respondents strongly endorsed a variety of reasons for enrolling their pet in the center, with quality of veterinary care and satisfaction of their pet’s basic needs being the most highly rated. Coding of open-ended responses was consistent with these ratings and identified having no other options as another frequently endorsed reason. The open-ended responses also indicated that respondents expected that their pet would enjoy extensive social interaction, receive high-quality medical attention, and be treated like they were at home. Respondents who had previously visited the center were more willing to adopt a pet in the future than those who had not visited the center. With the dramatic growth of pet life-care centers in the United States and lack of existing literature, further studies in this area are advised.     

Pet Loss and Representations of Death,Attachment, Depression,and Euthanasia

Studies that have examined pet loss hypothesize that attachment, representations of death, and the belief in an afterlife for animals may influence owners’ bereavement and depressive outcomes. The following instruments were administered to 159 Italian participants recruited through snowball sampling: the Lexington Attachment to Pets Scale (LAPS), the Pet Bereavement Questionnaire (PBQ), the Testoni Death Representation Scale (TDRS), and Beck’s Depression Inventory II (BDI-II). Questions concerning pet euthanasia-related issues and the relationship between owners and veterinarians were also submitted to the participants. A path model was conducted, showing that the representation of death and the attachment to a pet had a direct effect on pet grief, which in turn had a direct effect on depression. The results show a positive correlation between the LAPS and PBQ factors, particularly with the PBQ factor Grief. The LAPS factors positively correlated with the TDRS representation of Death as a Passage and negatively correlated with the TDRS representation of Death as Annihilation. The LAPS People Substituting factor positively correlated with the total score and the Cognitive-Affective factor of the BDI-II. The PBQ factors positively correlated with the BDI-II, whereas only the TDRS Death as Annihilation factor positively correlated with the BDI-II. Belief in a transcendent dimension was associated with higher scores on the PBQ Guilt factor and the TDRS factors of Death as a Passage and Death as Change, whereas these beliefs were associated with lower scores on the TDRS factor Death as Annihilation.

The results indicated that the sensitivity of the veterinarian and a veterinarian who helps owners make conscious and informed decisions for their pet and choose the right time to perform euthanasia are important variables in the management of pet loss. However, these factors are not sufficient and psychological support should be improved to help owners better cope with grief.     

Influence of pet ownership on opinions towards the use of animals in biomedical research

Abstract

The present study investigated the relationship between pet ownership and opinions on the use of animals in medical research. A questionnaire was answered by 484 schoolteacher students and 156 pre-school teacher students from Uppsala University, Sweden. Animal use was found to be of significant importance for developing treatments for human disease by 59 percent of respondents, but 15 percent did not agree. Forty-four percent thought that it was morally acceptable to use animals in biomedical research, while 25 percent did not. A significantly higher proportion of those who reported experience in the use of animals in research from university teaching morally accepted and understood the importance of using animals in biomedical research, compared with students without this background. Fifty-eight percent of the students were pet owners and the most common species owned were the cat and the dog. A lower proportion of pet owners (39%) found it acceptable to use pet species in biomedical research than did non-pet owners (52%).     

Children with pets do not show higher empathy: A challenge to current views

Abstract

A group of children (n=137) were surveyed with respect to pet ownership and pet preferences to explore the link between the human–animal bond and empathy. The most notable findings—and contrary to our predictions—were: (1) there was no difference in empathy (Bryan Empathy Index) between pet owners and non-owners; (2) there was no correlation between empathy and attachment to pets (Companion Animal Bonding Scale); and (3) higher empathy scores were not related to pet-preference indicators. A more fine-grained examination of the pet-owning group only revealed differences with respect to type of animal owned. Higher empathy was evident with dog ownership as opposed to other pet types. However, this needs to be tempered by the equally interesting observation that lower empathy was related to cat ownership. Regardless of how ownership groups are configured, there is consistent evidence that differentiates cat owners (lower empathy) from dog owners (higher empathy). When pet ownership and pet preference are combined to form new groupings, again, the cat effects and dog effects are evident. Implications extend to the need: (1) for future research on the nature of the human–animal bond; (2) to explore the relationship between personality and animal bonding; and (3) to refine the questions surrounding the animal-based links to empathy, as well as other related constructs such as prosocial behaviour, compassion, self-esteem, self-control, autonomy, affection, stress, responsibility, and perhaps even emotional intelligence, career paths and community service.     

A Survey of Rabbit Handling Methods Within the United Kingdom and the Republic of Ireland

Rabbits are commonly kept in a variety of settings, including homes, laboratories, and veterinary clinics. Despite the popularity of keeping this prey species, little research has investigated current methods of handling. The aim of this study was to examine the experience of caregivers (owners and keepers) in using five handling methods commonly referred to in books written for companion animal (pet) owners and veterinary and/or laboratory personnel. An online survey was completed by 2644 respondents, representing all three of these groups, and breeders. Data were acquired to determine sources that participants used to gain knowledge of different handling methods, the methods they used and for what purposes they used them, and their perceptions of any associated difficulties or welfare concerns. Results indicated that participants most frequently used the method of supporting a rabbit’s body against a person’s chest, which was considered the easiest and most welfare-friendly method of the handling methods explored. “Scruffing with rear support” was the least used method and was considered to be distressing and painful for the rabbit. As rabbits are a terrestrial prey species, being picked up is likely an innately stressful experience. Additional research is encouraged to explore the experience of rabbits during handling to identify methods that can be easily used with the fewest welfare compromises.     

Baseline Knowledge of Potential Pet Toxins among the US General Public

In 2014, the American Society for the Prevention of Cruelty toAnimals Animal Poison Control Center fielded more than 167,000cases of potential nonhuman animal toxicosis. Concomitantly, thereremain limited free and reputable veterinary toxicology resourcesavailable for companion-animal (pet) caregivers (owners) seekingassistance and advice about potentially harmful exposures inanimals. The objective of this study was to assess pet toxicantknowledge among a representative sample of Americans andgauge the need for additional toxicology resources. The studyinvolved a survey designed to capture participants’ ability to identifypotential animal toxicants and what resource they would use ifan accidental toxic ingestion occurred. Participants were ableto correctly identify 52% of potential pet toxins. Women, olderparticipants and participants from the South expressed moreconcern about each potential pet poison. Approximately halfof participants indicated they would consult a veterinarian andwhereas most others indicated they would search the Internet formore information about pet toxicology. The findings suggest moreveterinary poisoning education is needed for pet owners to be ableto accurately distinguish potential pet toxicants from nontoxicants.     

Use of a conditioning technique to reduce stress associated with repeated intra-peritoneal injections in laboratory rats

We hypothesized that using classical conditioning to pair a stressful procedure such as injection with a rewarding experience decreases the stress associated with repeated exposure to this procedure. We investigated the effectiveness of pairing repeated intra-peritoneal injections with a positive stimulus to reduce physiological and behavioural stress responses of laboratory rats by comparing injection with 1 ml/kg of saline followed by one of three different reward types (food treat (F), stroking (S) and tickling (T)), delivered in a treatment box, with two control conditions (handling without injection (CH) and injected (CI)) followed by an equivalent period in the treatment box. Treatments were applied to rats (N = 40; 8 rats/treatment) daily for 10 days. Audible and 50 kHz (laughing) vocalizations were assessed during handling and while in the treatment box. Chromodacryorrhea (an indicator of stress) was assessed daily in the home cage. Body weight, and behaviour in the Human Approach (HA) test, were assessed before (baseline) and after the 10-day treatment period. Behaviour in the Elevated Plus Maze (EPM) test was assessed after the 10-day treatment period. Rats on all treatments produced more chromodacryorrhea during the treatment period compared to baseline, suggesting that all treatments induced stress. Principal component analyses on behaviour in the HA and EPM tests revealed two and three factors that explained 86.8% and 98.7% of total variance, respectively. Multivariate analysis of variance on these factors, along with the other variables, revealed a significant contrast between CH and the other treatments. CH rats performed fewer audible vocalizations when handled compared to rats given injections. We found no clear benefit of providing a food treat, stroking, or tickling to alleviate stress associated with injection under the conditions of this study, possibly due to differences between rats in their perception of the aversiveness of handling restraint and injection, their stress response style (active or passive), and their perception of the pleasantness of the different rewards. Rats on all treatments emitted 50 kHz chirps in the treatment box, suggesting that being placed in the box after handling was rewarding regardless of treatment.     

The Pet Factor - Companion Animals as a Conduit for Getting to Know People,Friendship Formation and Social Support

Background

While companion animals have been previously identified as a direct source of companionship and support to their owners, their role as a catalyst for friendship formation or social support networks among humans has received little attention. This study investigated the indirect role of pets as facilitators for three dimensions of social relatedness; getting to know people, friendship formation and social support networks.

Methods

A telephone survey of randomly selected residents in four cities, one in Australia (Perth; n = 704) and three in the U.S. (San Diego, n = 690; Portland, n = 634; Nashville, n = 664) was conducted. All participants were asked about getting to know people within their neighborhood. Pet owners were asked additional questions about the type/s of pet/s they owned, whether they had formed friendships as a result of their pet, and if they had received any of four different types of social support from the people they met through their pet.

Results

Pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners (OR 1.61; 95%CI: 1.30, 1.99). When analyzed by site, this relationship was significant for Perth, San Diego and Nashville. Among pet owners, dog owners in the three U.S. cities (but not Perth) were significantly more likely than owners of other types of pets to regard people whom they met through their pet as a friend (OR 2.59; 95%CI: 1.94, 3.46). Around 40% of pet owners reported receiving one or more types of social support (i.e. emotional, informational, appraisal, instrumental) via people they met through their pet.

Conclusion

This research suggests companion animals can be a catalyst for several dimensions of human social relationships in neighborhood settings, ranging from incidental social interaction and getting to know people, through to formation of new friendships. For many pet owners, their pets also facilitated relationships from which they derived tangible forms of social support, both of a practical and emotionally supportive nature. Given growing evidence for social isolation as a risk factor for mental health, and, conversely, friendships and social support as protective factors for individual and community well-being, pets may be an important factor in developing healthy neighborhoods.     

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.     

Exotic Animal Companions and the Personality of Their Owners

ABSTRACT

The present study explored sex-specific differences in the Big Five factors of personality between different pet ownership groups, in order to understand individual differences in the choice of companion animals. A total of 250 pet owners completed a German version of the NEO-Five Factor Inventory (NEO-FFI). For the first analysis, participants were divided into four broad groups: those owning traditional pets (e.g., cats, dogs), those owning cold-blooded exotic pets, those owning warm-blooded exotic pets, and those not owning animals. For the second analysis, participants were subdivided into nine groups, based on species of animal owned: cats, dogs, birds, fish, reptiles, spider/insect, small mammals, owners of many different animals, and non-owners. In both analyses, separate analyses of variance were applied to the scores of the NEO-FFI scales. Interaction effects between sex and several ownership groups on the traits Openness to Experience and Agreeableness were found in both analyses. Female owners of traditional pets scored, for example, significantly lower on openness to experience than female owners of cold-blooded exotic pets as well as male owners of traditional pets. Furthermore, female owners of cold-blooded exotic pets scored significantly higher on openness to experience than their male counterparts. Regarding agreeableness, male owners of cold-blooded exotic pets scored significantly lower than their female counterparts as well as male owners of traditional pets. These and other results indicate that personality may affect choice of pets—but in different directions for the two sexes.     

There for You: Attending Pet Euthanasia and Whether this Relates to Complicated Grief and Post-Traumatic Stress Disorder

ABSTRACT

Recognizing the deep relationship between grief and the loss of a companion animal, veterinarians and mental health practitioners often find themselves consoling pet owners both prior to and in the aftermath of pet euthanasia. Yet how does euthanasia influence this bereavement process? To explore this we examined, using a survey, the correlations between pet euthanasia, Complicated Grief (CG), and Post-Traumatic Stress Disorder (PTSD) amongst a diverse range of pet owners from the state of Hawaii. Participants (n = 236) completed a 37-item questionnaire, the Inventory of Complicated Grief Revised Short Form (ICG-R-SF), and the PTSD Checklist (PCL). Of the participants, 3.4% and 4.7% met the criteria for CG and PTSD, respectively. This paper explores and subdivides respondents into those who attended their companion animal’s euthanasia and those who did not. Our results indicate that physically attending a companion animal’s euthanasia is not correlated with CG or PTSD. As the experience of pet loss itself may be more indicative of psychological distress than whether or not the owner was present at the moment of euthanasia, veterinary staff need not dissuade pet owners from sharing their pet’s final moments.
