ABSTRACT The experience of grief and loss is a process that can be extremely distressing to anyone, regardless of age. This may be especially true for youth. This study was designed and conducted to determine the effects of a therapy dog as a therapeutic adjunct in Child Life interventions with adolescents experiencing grief and loss. Subjects were randomly assigned to one of two groups. The intervention consisted of 3 sessions with a Certified Child Life Specialist (CCLS) to address grief. Group 1 (N=14) was the control group, meeting only with the CCLS. Group 2 (N=13) was the experimental group and met with the CCLS with a therapy dog present during the sessions. Participants completed a pre-test and post-test of the Children's Mood Questionnaire. At the end of each session, subjects completed a Therapeutic Engagement Questionnaire. The pet therapy group experienced a significant improvement in mood scores on the Children's Mood Questionnaire following the intervention. However, there were no significant differences between groups on the Therapeutic Engagement Questionnaire during any of the 3 sessions. The data collected from this study indicate that the addition of a therapy dog in grief interventions with adolescents may improve mood outcomes.

Description
Due to artificial selection, dogs have high levels of phenotypic diversity, yet, there appears to be low genetic diversity within individual breeds. Through their domestication from wolves, dogs have gone through a series of population bottlenecks, which has resulted in a reduction in genetic diversity, with a large amount of linkage disequilibrium and the persistence of deleterious mutations. This has led to an increased susceptibility to a multitude of diseases, including cancer. To study the effects of artificial selection and life history characteristics on the risk of cancer mortality, we collected cancer mortality data from four studies as well as the percent of heterozygosity, body size, lifespan and breed group for 201 dog breeds. We also collected specific types of cancer breeds were susceptible to and compared the dog cancer mortality patterns to the patterns observed in other mammals. We found a relationship between cancer mortality rate and heterozygosity, body size, lifespan as well as breed group. Higher levels of heterozygosity were also associated with longer lifespan. These results indicate larger breeds, such as Irish Water Spaniels, Flat-coated Retrievers and Bernese Mountain Dogs, are more susceptible to cancer, with lower heterozygosity and lifespan. These breeds are also more susceptible to sarcomas, as opposed to carcinomas in smaller breeds, such as Miniature Pinschers, Chihuahuas, and Pekingese. Other mammals show that larger and long-lived animals have decreased cancer mortality, however, within dog breeds, the opposite relationship is observed. These relationships could be due to the trade-off between cellular maintenance and growing fast and large, with higher expression of growth factors, such as IGF-1. This study further demonstrates the relationships between cancer mortality, heterozygosity, and life history traits and exhibits dogs as an important model organism for understanding the relationship between genetics and health.

Description
Dogs' health and wellbeing is of great importance to their owners. The most common nutritional problem for pet dogs is obesity, with 22-40% of pet dogs being classified as overweight or obese. With many adverse health effects associated with obesity, this is a major concern for owners and veterinarians. The degree to which dogs enjoy consuming certain foods can have substantial implications for their body weight, so it is important to understand which aspects of foods make them appealing to dogs. This study aimed to determine whether nutritional aspects of commercial dog foods predict dogs' preferences for those foods. It was found that consumption preference is positively correlated with protein content (p < .001), therefore implying that the protein content of commercial dry dog foods may predict dogs' consumption preferences. Consumption preferences were not predicted by other available measures of food content or caloric value. Dogs' preference for foods high in protein content may be due to the satiating effect of protein. Since foods high in protein both reduce the amount of energy consumed and are found to be palatable to dogs, high-protein dog foods may offer a way for dog food manufacturers, veterinarians, and pet owners to combat obesity in pet dogs.

Description
My thesis is an experiment in the power of social media and networking. The compelling question is: How can we as journalists motivate people to connect with Facebook/blog postings enough to share them with their own networks? This is a huge issue with journalism because it is a challenge to move people and to get them to share information.
My thesis project took the form of a networking blog for adoptable animals at the local pound. I created unique photos of the dogs and wrote up bios for them so that they became more accessible to people who could not physically visit the shelter very often. I brought the dogs to life by sharing a part of their story and encouraging people to care about what happened to them. This issue is especially close to my heart because I have loved animals all my life and started fostering dogs a few years ago.
The project was a huge success. I profiled 37 dogs and they amassed hundreds of thousands of views both on my Wordpress site and on the project Facebook page. Five of my dogs were euthanized, about a 13% euthanasia rate. Compared to the owner surrender euthanasia rate of previous years, this rate is remarkably low. In 2012, about 43.86% of owner surrenders were euthanized. In 2013, about 39.19% of owner surrenders were euthanized. In 2014, about 33.27% of owner surrenders were euthanized. My euthanasia rate was essentially less than half of the last year’s owner surrender euthanasia rate.
I think I absolutely proved my point. The power of networking in unique ways and leveraging the influence of social media cannot be underestimated. Less dogs were killed because of my project. If that’s not success, then I don’t know what is.

Description
This thesis explores how we can harness new technology to improve our relationship with companion animals and promote shelter animal welfare. The study looked into using the photo-sharing application Instagram to increase adoption rates at the Arizona Animal Welfare League & SPCA. An Instagram page was created and managed for the shelter, and data was collected regarding the impact the page had on adoption rates. The results were mixed, but overall it was determined that the Instagram page has unique value for the shelter.

Description
Brief memory tasks for use with pet dogs were developed using radial arm maze performance as a standard comparison measurement of memory capacity. Healthy pet dogs were first tested in a radial arm maze, where more errors made in completing the maze indicated poorer memory. These dogs were later tested with five novel memory tests, three of which utilized a treat placed behind a box with an identical distracter nearby. The treat placement was shown to each dog, and a 35 second delay, a 15 second delay with occluder, or a 15 second delay with room exit was observed before the dog could approach and find the treat. It was found that errors on the delayed match to sample (35 second delay) and occluder/object permanence (15 second delay with occluder) tasks were significantly positively correlated with the average number of errors made in the 8th trial of the radial arm maze (r =.58, p<.01** and r =.49, p<.05*, respectively) indicating that these new brief tests can reliably be used to assess memory in pet dogs.

A collection of poems concentrating on 15 small moments, tied together to explore the ardor, tensions, and fragility a relationship. Conceptions of language, teeth, domesticated dogs, and a car accident recur throughout the manuscript as a means of navigating this narrative and of questioning the role of memory in our lives.

Description
There are many anecdotal stories of dogs rescuing their owners from dangerous situations, but this rescue behavior has yet to be shown in an experimental setting. Studies have shown that dogs behave differently towards crying humans, but do not seek help for their owners when they are in distress. This study sought to determine if a dog could recognize when its owner was in distress and would attempt to rescue the owner. The experiment consisted of three conditions: a distress condition to determine how dogs respond to an owner calling for help, a reading condition to control for proximity-seeking and sound, and a food control to use as a basis for motivation and door-opening ability of the dog. Sixty dogs were tested in all three conditions in a pseudo-random order so that an equal number of dogs completed the conditions in each order. 38% of the dogs opened the apparatus for any condition, while 32% opened for the food and distress conditions and 27% opened for the reading condition, which shows that rescue in general is unlikely. There was no significant difference in the proportion of dogs who opened the apparatus for each condition, indicating that dogs are no more likely to rescue their distressed owners than they are to open the apparatus for other conditions and may not be able to sense that the owner is in distress. The similarities in the success rates also show that the owner can be just as motivating for a dog as food. Overall, the low success rates suggest that dogs are not generally likely to rescue a person who is trapped, even when they are calling for help.

Description
Previous research pertaining to dog memory and cognition has been confined mainly to samples of colony dogs and therefore can be hard to generalize to a larger population of pet dogs and varying breeds. The present study focused entirely on pet dogs of many different breeds, rather than colony or laboratory animals for the purposes of accessibility, affordability, and novelty. Methods: We presented the dogs with a memory task in the form of a game in which the dogs chose to search for food at one of two locations at varying delay intervals, with a maximum time limit of one hour per dog. We expected our data to show a significant decrease in memory capacity and an increase in error rates among older dogs as compared to younger dogs; these results would allow us to conclude that it is likely many dogs, much like humans, experience various cognitive deficits as a function of increasing age. Results: Using one-factor ANOVA and linear and curvilinear regression analyses, we examined the relationship between the independent variable, age (individual dog ages as well as three generalized age categories), and three dependent variables. The dependent variables were: (a) percentage of correct choices at a 60 second delay interval, (b) maximum delay interval attempted (MDIA), and (c) the maximum delay interval that was completed above chance level (50%) (MDAC). We found significant results to support our hypotheses that aged dogs show spatial memory and cognitive deficits in comparison with young and middle-aged dogs, and that age can be considered a marginally significant predictor of spatial memory capacity.

Description
We compared sociability towards humans of domesticated and tame members of several Canidae: Belyaev's fox (Vulpes vulpes), red fox (Vulpes vulpes), gray wolf (Canis lupus), dingo (Canis l. dingo), New Guinea singing dog (Canis l. dingo), and dog (Canis l. familiaris). We defined sociability as motivation or willingness to engage with humans. Our operationalized definition of sociability is the latency to approach (LTA) the human experimenter and the amount of time the canid spent within one meter of the human experimenter (PTC). We added an unfamiliar and familiar experimenter condition to deduce whether or not canids discriminated on who they were more social with: an owner or a stranger. To each experimenter condition we added a passive and active phase to discern whether or not canids were more social when called or not. Across all conditions and phases dogs were significantly more social than all other canid types. We concluded genetic differences due to domestication and environmental differences due to socialization accounted for sociability differences seen in dogs compared to the other canid types.
