Elderly people are at high risk for conditions associated with inactivity, and lack of motivation is an important factor contributing to this inactivity. It is believed that a dog can provide the necessary motivation to get a senior citizen up and moving because it needs attention as well as someone to feed it and take it for walks. The objective of this five-week prospective cohort study was to determine if registered therapy dogs made available for informal visits to a cohort of retirement community elderly would motivate the subjects to increase their activity levels by comparing the number of steps taken in the presence of the exposure (opportunity to visit with dog) versus steps taken when unexposed (no opportunity to visit with dog). A secondary objective was to measure possible improvements in mental and physical health scores over the course of the study. The steps were measured each week with a pedometer and the happiness and depression scores were obtained through a questionnaire given at the beginning and at the end of the study. Twenty subjects agreed to participate, and there was an increasing trend in the number of steps over calendar weeks, but not an increase with exposure level (number of dog-visits). Happiness (p = .53) and depression (p = .083) scores did not significantly change during the study. Increased step counts each week may have been associated with other motivating factors such as competition among residents and individual desire to achieve higher counts each week.

Doctor of Philosophy / Special Education, Counseling and Student Affairs / Fred O. Bradley / The broaden-and-build theory posits that frequently experiencing positive emotions leads to broadened awareness and functioning, and over time, built resources. These resources function as reserves during difficult times. Considering recommendations for increasing positive emotions and findings regarding human-animal interactions, it is reasonable to expect that companion animals might function in a manner to increase positive emotions. Many people have companion animals, and they are a preventative, natural intervention without associated stigmas. Therefore, knowing more about how companion animals impact their humans has practical implications for mental health professionals. The current study investigated various aspects of human-animal interactions that are conceivably related to positive emotions (human-animal bond and amount of time spent with animal) in different configurations (people with and without companion animals; people with dogs, cats, and horses), while considering potential confounds (time spent with humans in connected interactions and time spent outside). Time spent in connected interactions with other humans is the only variable that predicted positivity, and this was only in people without companion animals. This is consistent with previous findings that interacting with other people is related to positive emotions.

<p>Humans and domesticated animals have lived alongside one another for thousands of years, yet scholars have only recently begun to examine how companion animals, or pets, influence human lives (Knight, 2005). Today, 67 percent of United States households contain companion animals (APPA, 2019-2020) and many people consider their pets as family (Irvine & Cilia, 2017; McConnell et al., 2019). Given this, the death and dying period for pets can bring about distinctive concerns and difficulties within the family system, yet little is known about how individuals navigate the pet end-of-life period within the family, and how family communication manifests in this context. This study aimed to understand the interactional challenges for families communicating about the end-of-life period for their pets. Guided by family systems theory (FST) as an analytic framework, the goal was to better understand these dynamics using qualitative methods to address two main research questions. First, what are the challenges families face during the companion animal death and dying period? And second, how do families respond communicatively to these challenges? This qualitative study used a grounded theory approach to analyze 27 in-depth interviews with individuals who had experienced a death of their pet in the prior year and centered on how families described the place of their pets within the system. Of those participants, 14 individuals consisted of family dyads (51%) in various subgroups of partners, parent-child and siblings. Analysis affirmed some of what is known from the literature (such as feelings of guilt and financial worries associated with pet end-of-life) but also extended what is known by documenting family decision-making dilemmas, such as the dialectic tension between holding on and letting go, as well as noting the reverberations through the family of avoiding talk about death and disruptions to family communication after death. This manifested in primarily a decrease in talk about the pet or talk with family members (both in-person and mediated channels) or an increase in talk following the death. These findings suggest that pet death has the potential to disrupt a family's regular communication patterns.</p> <p>These findings affirmed that supportive communication after a death loss is important to individuals and particularly helpful from others with prior pet loss experience. Along with social support, participants indicated that the artifacts left behind after the death of their pet provided comfort and were also elements of tension and cohesion within the system. As scholars suggest, companion animals are liminal creatures, existing as kin and "other" within the family (Irvine & Cilia, 2017; Sayers et al. 2022). Indeed, participants described their pets as existing in a space at the edge of true family member whose fate was exclusively in the hands of the family, particularly in the context of euthanasia, which contributed to some of the communicative challenges identified. </p> <p>Given limitations of a mostly regional and homogenous sample and the conceptual limitation of extrapolating from two individuals in a family to the whole system, this study was still able to take the next step needed for understanding the communicative challenges faced by families in confronting pet death. Findings extend the concept of pet-as-family, in that pets were found to be an element of the "family tapestry" serving the role of both emotional support and kin for some family members. In that manner, they were also discovered as integral to the family timeline, a catalyst for connection between family members, and thus worthy of further study from a communication and family system perspective.</p>

Master of Science / Food Science / Edgar Chambers IV / Palatability of pet foods is judged by the use of animals in colonies. Pet food manufacturers would like to understand how palatable a food is compared to another food. This generally is accomplished by a two pan test where a pet has the opportunity to freely choose between two foods. Preference is evaluated through the use of an intake ratio, the ratio of the amount of test food consumed divided by the total amount of the foods consumed. Although this is easy to do in laboratories, another option would be to do such studies with animals in more ‘real-life’ home environments. The purpose of this study was to develop, and test a method to capture feeding information from a study of canines in the home environment and analyze the results of the palatability tests. Individual dog owners were screened for information on the household and pets. Twenty-five dogs of different ages, breeds and sizes were selected to participate on the in-home panel. Seven different palatability tests were performed using the in-home panel with four of those tests being replicated; a total of 11 comparative tests. These dogs were tested using a proprietary computer-based technology that collected information about intake of each food for each individual dog for a duration of seven days for each of the 11 comparative studies. Data was analyzed and resulted in showing that differences between foods can be found. Statistical analyses compared initial day one data to subsequent day data collected during each study to determine whether a full seven day test was needed. In addition, comparisons were made to compare the impact of prior foods eaten to subsequent preferences of the dogs. Results of the in-home panel were the same on day one as for all seven days of testing. Also, previous exposure to a food did not alter subsequent preference for that food. Such data has implications for pet food manufacturers related to timing and cost of testing.

This thesis expands on the model presented in Sue Donaldson and Will Kymlicka’s Zoopolis for how companion animals might be treated as co-citizens in a post-Animal Rights world. I will attempt to clarify the distinct political obligations owed to companion animals throughout their lifetimes by individual caregivers and by the state. In particular, I argue that there is nothing in the genetic make-up of most companion animals that precludes them from being “autonomous agents” in adulthood, meaning that if allowed to develop their agency, most animals would be able to lead flourishing lives independent of human companions. I suggest that, for young companion animals, guardians have political obligations to develop the autonomous agency of their dependents, with help from the state. That said, for adult animals which develop autonomous agency, I argue that both a human caregiver and the animal have a right to sever their relationship with each other, just as we give adult children the right to leave their parents’ care and also give parents the “right to kick out” adult children who are capable of supporting themselves. However, while advocating for human caregivers’ rights to sever relationships with autonomous pets, I nonetheless maintain that the state will always retain obligations to its citizens to provide them with a basic level of welfare, and these obligations extend to companion animals as well. Thus, the thesis will consider ways that companion animals can flourish without human companionship. Questions I am concerned with are: Can companion animals lead worthwhile lives without human caregivers? What obligations do caregivers and states have to raise animal young? When and how can these obligations be terminated? And lastly, how might we restructure our public and political institutions to accommodate animals who voluntarily or involuntarily leave relationships with caregivers? / Thesis (Master, Philosophy) -- Queen's University, 2013-11-15 09:18:40.613

The study of cat personality and behaviour can help minimize potential problems in the relationship between cats and their tutors and decrease relinquishment or maltreatment. Personality in animals is a promising area dedicated to studying characteristics of individuals that describe and account for temporally stable patterns of affection, cognition and behaviour traits. In general, people adopt cats according to their appearance, age or sex. Personality assessments can promote successful adoptions by identifying ideal animals for potential tutors. The American Society for the Prevention of Cruelty to Animals (ASPCA) has implemented a program called Meet Your Match® (MYM) which assesses the personality of shelter cats and the life style of adopters. With a better match between cat and tutor, the rate of animals being returned to shelters tend to decrease and cats welfare and adaptation in new homes tend to improve. To evaluate physiological stress and personality dimension, faecal cortisol metabolites (FCM) levels were measured and a modified MYM protocol was applied in two localities: a shelter and the tutors home. Our main goals were: 1) verifying the validity of personality dimensions used in a modified MYM assessment in a Brazilian cat shelter sample through an exploratory study of the psychometric properties of the protocol, as well as an exploratory factor and a cluster analysis; 2) verifying the correlation between personality and faecal cortisol levels; 3) checking if MYM assessment is consistent through change of localities; and 4) finding out how moving from the shelter to the tutors home affects faecal cortisol metabolites levels. We found evidence of validity of the modified MYM assessment based on internal structure to personality dimensions in this sample, although it presented a factorial structure that differs from the original assessment. No correlation was found between personality dimensions and FCM levels, corroborating the literature. There was a slight decrease of FCM levels in homes, but most subjects maintained their FCM levels, showing that cats can cope with stress in both environments the shelters and the tutors home. MYM personality assessment was consistent throughout the change of localities, which indicates that it is a good instrument to assess cat personality / O estudo sobre comportamento e personalidade dos gatos pode ajudar a minimizar possíveis problemas na relação entre gatos e seus tutores e diminuir o abandono e os maus tratos.

Para avaliar o estresse fisiológico e as dimensões da personalidade, metabólitos fecais de cortisol (MFC) foram medidos e a avaliação MYM foi aplicada em duas localidades: um abrigo e a residência do tutor. Nossos principais objetivos foram: 1) verificar a validade das dimensões de personalidade utilizadas na avaliação do MYM em uma amostra de abrigo brasileiro, por meio de um estudo exploratório das propriedades psicométricas do protocolo, uma análise de fator exploratório e uma análise de cluster; 2) verificar a correlação entre os tipos de personalidade e o cortisol fecal; 3) verificar se a avaliação do MYM foi consistente após mudança de localidades (abrigo e casa); e 4) verificar como a mudança do abrigo para a casa do tutor afeta os níveis de cortisol fecal. Encontramos evidências de validade da avaliação MYM modificada, baseadas na estrutura interna das dimensões da personalidade nesta amostra, embora a estrutura fatorial tenha sido diferente da avaliação original. Não foi encontrada correlação entre as dimensões de personalidade e os níveis de MFC, corroborando a literatura. Houve uma discreta diminuição dos níveis de MFC nas casas, mas a maioria dos indivíduos manteve seus níveis de MFC, mostrando que os gatos lidam bem com o estresse nos dois ambientes o abrigo e a casa do tutor. A avaliação de personalidade do MYM foi consistente na mudança de localidades, o que indica que ela é um bom instrumento para avaliar a personalidade de gatos

Breast cancer is the most common cancer in women and unspayed female dogs. The Epithelial to Mesenchymal Transition (EMT) is a process involved in embryogenesis, carcinogenesis, and metastasis. The Transforming Growth Factor- Beta (TGF-β) pathway and its associated transcription factors are crucial for EMT induction, during which epithelial cells lose their defining characteristics and acquire mesenchymal properties. EMT has been implicated as a driver of metastasis as it allows cells to migrate and invade different organs. Recent evidence indicates that cancer stem cells are required to establish metastatic tumours at distant sites, and that EMT may promote development of cancer cells with stem-cell characteristics, thus, the EMT pathway may be an important molecular determinant of tumour metastasis. The main objective of this project was to characterise TGF-β-induced EMT in breast cancer models. EMT was induced by TGF-β in human, canine and feline breast cancer cell lines, and confirmed by morphological changes and molecular changes at the protein level by Western blot analysis. Changes at the mRNA level were confirmed in human and canine mammary carcinoma cell lines by qRT-PCR; migratory properties were assessed by invasion assays in vitro in feline and canine mammary carcinoma cells. Importantly, we observed that feline and canine mammary carcinoma cells stimulated by TGF-β acquired stem cell characteristics including sphere-forming ability, self-renewal, and resistance to apoptosis, and also enhanced migration potential. Canine cells showed resistance to chemotherapeutic drugs after TGF-β stimulation. These data suggests a link between EMT and cancer stem-cells. Moreover, global changes in microRNA expression were mapped during TGF-β-induced EMT of canine mammary carcinoma cells. This gave significant insight into the regulation of EMT in canine cancer cells and identified several potential targets, which require further investigation. During EMT cells acquire migratory properties and cancer stem-cell characteristics, suggesting that EMT and the stem-cell phenotype are closely related during cell migration and metastasis, therefore making the TGF-β pathway a potential target for the development of novel therapies against cancer and its progression.

Over 71% of American homeless individuals are adults over 25 years of age, and the numbers are increasing. Approximately 25% of homeless individuals own a companion animal (CA). Because most service providers do not allow CAs within their facilities, the current $60.2 billion dollar national budget for homeless resources may be underutilized or forfeited altogether by homeless adults with a CA. The purpose of this study was to explore community service utilization by homeless adults with a CA through the lens of attachment theory. The research question addressed the lived experiences and perceptions of homeless adults who own CAs regarding community service utilization. This is a qualitative, hermeneutic phenomenological study in which 11 participants were interviewed individually from a semi-structured, researcher created questionnaire. Participants were homeless adults at an emergency shelter in Texas or Oklahoma where their CAs were allowed. Through coding and thematic analysis, 3 themes developed: familial attachment to a CA, a willingness to forego services that do not accommodate their CA, and false belief in their CA as a necessary service provider. The results of this study builds upon the existing body of knowledge regarding homelessness, CAs, and community services as well as informs service provision, education, and policy. Positive social change implications include awareness of the perceptions and beliefs provided by this unique unsheltered sub-population who experienced physical illnesses, trauma, and a close familial bond with their CA. Their lived experiences are key indicators for community service providers and governmental organizations consideration in reference to budgeting allocations and future research.

Researchers have demonstrated clear benefits to humans in their relationships with companion animals; however, little is known about how these animals may benefit from their relationships with humans. The purpose of the current study is to investigate potential benefits to a pet of living in a household, as defined by an array of specific pet owner behaviors. A second purpose is to investigate the relationship between self-reported attachment to a pet and dimensions of potentially beneficial owner behaviors on behalf of that animal. Participants in the current study were pet-owning undergraduate students (N = 501) from a large Midwestern university who were surveyed on an array of behaviors they may perform for or with a companion animal. Self-reported attachment to the animal was measured using the Lexington Attachment to Pets Scale (Johnson, Garrity, & Stallones, 1992). Factor analysis resulted in five dimensions of behavior for dog owners (n = 350), named Indoor/Outdoor, Attention, Inclusion, Well-being, and Safety. Four dimensions were found for cat owners (n = 151) and named Indoor/Outdoor, Indulgence, Possessions, and Independence. The Indoor/Outdoor dimension was similar to factors found in previous research. The rest of the dimensions appear to be uniquely important in terms of either dog or cat ownership. Regression analysis using factor scores to predict attachment revealed that 38.6% of the variance in attachment scores for dog owners and 23.6% for cat owners was explained by the dimensions. The results of the factor analysis provide a picture of what human care giving might mean, in terms of beneficial behavior, to the animal. The results also indicate that the basic needs of companion animals are being met regardless of the degree of attachment: low attachment may not necessarily mean poor care. Attachment does, however, appear to make a difference in the life of a companion animal in terms of enrichment. Dog owners who report higher attachment tend to include the dog in family activities, and provide certain kinds of attentions. Cat owners who report higher attachment are more likely to have a cat that stays close by their side, and are also more likely to provide gifts and treats to the cat. / Thesis (Ph.D.)--Wichita State University, College of Liberal Arts and Sciences, Dept. of Psychology. / "May 2005."
