The “Black Dog” syndrome is a phenomenon in which black dogs and cats are seen as less desirable, less adoptable, and more likely to be euthanized.  This has been seen anecdotally by animal shelter workers for years but given the limited detailed records that many shelters keep, there is little empirical evidence of this.  This study examines how our opinions towards pets may be influenced by their color.

Sixty-five participants (24 males, 42 females, M=21.09, SD=7.20) completed the study.  Participants were shown pictures of both cats and dogs of varying colors and breeds and answered questions relating to perceived attributes about the animal including whether the animal was friendly, aggressive, and adoptable.

There was a main effect for friendliness.  Further analysis revealed that the white cat was considered the friendliest followed by the orange cat, while the black cat was the least friendly.  Similarly, the yellow dog was considered the friendliest while the brown dog was second, and the black dog was last.  This trend also held true for the perceived adoptability such that the lighter colored pets were considered more adoptable than the darker colored ones.  Lastly, there was a main affect for aggression.  The black dog was considered the most aggressive followed by the brown dog, and the yellow dog.

The results of this study do indeed indicate a bias in opinions of different colored dogs and cats.  By researching this problem, we may be one step closer to answering the question of why some dogs and cats are seen as less adoptable than others which could lead to adoption programs dedicated to addressing and resolving this issue through education and outreach.

Over the last decade, there has been renewed interest in understanding the mechanisms that control contagious yawning.  Contagious yawning has been linked to empathy in humans and other primate species.  However, cross-species studies of contagious yawning between dogs and humans have reported less consistent findings.  It has been suggested that contagious yawning in dogs may be the results of stress rather than low-level empathy, since dogs produce “tension yawns” in uncertain situations.

We investigated the role of arousal in what has been interpreted as yawn contagion in dogs in order to better understand the physiological processes that underlie yawning in a stressful context.  Sixty shelter dogs were exposed to yawning and non-yawning control stimuli demonstrated by an unfamiliar human.  We took salivary cortisol samples before and after testing to determine the role of arousal in yawn contagion.  The cortisol levels of dogs that yawned only in response to human yawning remained elevated following testing, whereas other dogs had reduced cortisol levels relative to their baseline levels.

These findings are in contrast to current ideas in the dog training community that dogs perceive human yawning as a calming signal that reduces stress.  We suggest that arousal states may have a substantial influence on how human yawns are perceived by dogs.  Specifically, when a human yawn is presented in situations of uncertainty when arousal is high, as in shelter dogs, it may be perceived as a signal for stress.  Some dogs then yawn as a means of displacing internal anxiety.  Therefore, yawning between humans and dogs may involve some communicative function that is modulated by context and arousal.

The loss of a companion animal is well accepted to result in a significant experience of grief for the owners although, at present, little is known about how other animals in the household are affected by such a loss.  This paper discusses how companion animals’ respond to the loss of a conspecific through owner reported behavioural changes.

A questionnaire was distributed via informative publications produced by the Royal Society for the Prevention of Cruelty to Animals (RSPCA) across Australia and New Zealand and through a selection of veterinary clinics with New Zeland.  The questionnaire covered owner demographics, demographics of up to four deceased animals and up to four animals remaining in the household after an animal companion passed away, behaviour that was exhibited or that changed in remaining animals after a companion passed away and the duration of these behaviours.

From a total of 306 returned questionnaires, 414 companion dogs and cats had experienced the loss of an animal companion.  Seventy five percent of these animals were reported to display a behavioural change by their owner.  Dogs were reported to display a reduction in food consumption, an increase in sleeping, a decrease in vocalisations and were described as appearing withdrawn.  These behavioural changes were more often described if the deceased conspecific was also a dog.  Cats, on the other hand, were reported to display an increase in vocalisations, an increase in aggression towards other animals in the household and were described as appearing depressed.  The behavioural changes described in cats were also more often reported if the deceased conspecific was a cat.

These findings demonstrate that owners describe common behavioural changes in their companion animals, subsequent to the loss of a conspecific.

The “Bali Street Dogs” of Indonesia are largely owned, but few receive adequate guardianship.  Veterinary and zoonotic health concerns, animal abuse, and social conflicts over dog issues have escalated particularly since the introduction of rabies to Bali in 2008.

In order to understand the relationship of Balinese with their dogs and to advance the welfare of animals and communities in this context, we initiated a participatory community dog welfare project in Gianyar Regency in January 2012.  Participatory methods were developed in the international humanitarian aid sector, and have been adapted to the care of equine and bovine working animals.  The Bali dog project seeks to adapt these methods to the care of animals whose value in communities is not primarily economic.

The first year of the project engaged 13 communities (banjars) through sequential facilitated community meetings, individual discussions and limited veterinary services.  Communities warmed quickly go topics of dog guardianship which they had hitherto not considered in the context of community, or solvable, concerns.  The many questions and discussions on animal care, human-dog conflicts and rabies reflected an inherent compassion for dogs that is compromised by a lack of understanding in how to care for them properly and powerlessness against social and political pressures.

At the end of the first project year, attitudes toward dogs had improved markedly, primarily due to the empowerment derived from understanding issues and recognizing possibilities for addressing them.  This perception and the underlying feeling of “ownership” provides momentum, for the long-term engagement of communities in the project.

The necessary balance of anthropological and scientific skills is important and productive for furthering the participatory approach, but stretches staff resources and challenges collection of scientific data.  A priority for Year 2 is the integration of a feasible monitoring system to assess improvements in animal welfare.
