Ubicomp for animal welfare: envisioning smart environments for kenneled dogs

Whilst the ubicomp community has successfully embraced a number of societal challenges for human benefit, including healthcare and sustainability, the well-being of other animals is hitherto underrepresented. We argue that ubicomp technologies, including sensing and monitoring devices as well as tangible and embodied interfaces, could make a valuable contribution to animal welfare. This paper particularly focuses on dogs in kenneled accommodation, as we investigate the opportunities and challenges for a smart kennel aiming to foster canine welfare. We conducted an in-depth ethnographic study of a dog rehoming center over four months; based on our findings, we propose a welfare centered framework for designing smart environments, integrating monitoring and interaction with information management. We discuss the methodological issues we encountered during the research and propose a smart ethnographic approach for similar projects

Identifying environmental and management factors that may be associated with the quality of life of kennelled dogs (Canis familiaris)

Abstract This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were allocated to one of four treatment groups, all of which had a positive (0.0 - 1.0) average quality of life score: long stay dogs with an enriched routine had a mean score of 0.477; long stay dogs with a standard routine had a mean score of 0.453; newly admitted dogs with an enriched routine had a mean score of 0.399; and newly admitted dogs with a standard routine had a mean score of 0.362. Only 2 of the dogs had a negative score (-1.0 - 0.0). Thirteen rehoming centre managers completed a questionnaire relating to the kennel environment and management practices of their rehoming centres. The environmental and management factorsâ�� associations with quality of life scores, collected from 202 dogs from the 13 rehoming centres using this scoring system, were analysed as fixed factors in a linear mixed-effect model, with rehoming centre fitted as a random factor, and a multiple linear regression model. There was a statistically significant association between quality of life scores and rehoming centre (H(12) = 54.153, p <0.001), however, the fitted linear mixed-effect model did not improve upon the null model and therefore cannot be used to explain the 29 variance in quality of life scores attributed to rehoming centre. The multiple linear regression model explained 42 of the variation in quality of life scores (F(10,131) = 9.318, p < 0.001): the provision of bunk beds increased quality of life scores by 0.3 (t = 3.476, p < 0.001); provision of 30 minutes or more of staff or volunteer interaction increased scores by 0.26 (t = -2.551, p = 0.012); grooming dogs decreased scores by 0.404 (t = 3.326, p = 0.001); exercising dogs more than once a day decreased scores by 0.173 (t = -3.644, p = <0.001), whereas exercising dogs for 30 minutes or more increased quality of life scores by 0.213 (t = -2.374, p = 0.019) and the provision of less common types of exercise increased scores by 0.504 (t = 5.120, p < 0.001); training dogs for 30 minutes or more every day increased scores by 0.688 (t = 3.040, p = 0.003) and training dogs less than daily decreased scores by 0.393 (t = -4.245, p < 0.001); feeding a diet of dry and wet food compared to dry food alone decreased scores by 0.08 (t = -2.331, p = 0.021); and a quiet environment increased scores by 0.275 (t = -3.459, p < 0.001). These results suggest that environmental design and kennel management have an impact on the quality of life of kennelled dogs and should be considered carefully in decision-making processes. However, further study may be required as grooming and exercising dogs more than once per day decreased quality of life scores, which are not obviously intuitive results

Parent perceptions of the quality of life of pet dogs living with neuro-typically developing and neuro-atypically developing children: an exploratory study

There is growing scientific and societal recognition of the role that pet dogs can play in healthy development of children; both those who are neuro-typically developing and those who live with a neuro-developmental disorder, such as autism or attention deficit hyperactivity disorder. However, little attention has been paid to how living with children positively and negatively affects quality of life of a pet dog. In this exploratory study we conducted semi-structured interviews with parents of neuro-typically developing children (n = 18) and those with a neuro-developmental disorder (n = 18) who owned a pet dog, until no new factors were identified. Living with children brought potentially positive benefits to the dog’s life including: imposition of a routine, participation in recreational activities and the development of a strong bond between the child and the dog. The importance of maintaining a routine was particularly prevalent in families with children with neuro-developmental disorders. Potential negative factors included having to cope with child meltdowns and tantrums, over stimulation from child visitors, harsh contact and rough and tumble play with the child. The regularity and intensity of meltdowns and tantrums was particularly evident in responses from parents with children with a neuro-developmental disorder. However, child visitors and rough play and contact were mentioned similarly across the groups. Protective factors included having a safe haven for the dog to escape to, parent’s awareness of stress signs and child education in dog-interaction. Parents were also asked to complete a stress response scale to provide an initial quantitative comparison of stress responses between dogs living with the two family-types. Parents with neuro-typically developing children more frequently observed their dog rapidly running away from a situation and less frequently observed their dog widening their eyes, than parents with children with a neuro-developmental disorder. We propose the development of a stress audit based on the findings reported here, to prevent potential dangerous situations, which may lead to dog bites and dog relinquishment and allow owners to maximise the benefits of dog ownership

Quick, accurate, smart: 3D computer vision technology helps assessing confined animals' behaviour

Mankind directly controls the environment and lifestyles of several domestic species for purposes ranging from production and research to conservation and companionship. These environments and lifestyles may not offer these animals the best quality of life. Behaviour is a direct reflection of how the animal is coping with its environment. Behavioural indicators are thus among the preferred parameters to assess welfare. However, behavioural recording (usually from video) can be very time consuming and the accuracy and reliability of the output rely on the experience and background of the observers. The outburst of new video technology and computer image processing gives the basis for promising solutions. In this pilot study, we present a new prototype software able to automatically infer the behaviour of dogs housed in kennels from 3D visual data and through structured machine learning frameworks. Depth information acquired through 3D features, body part detection and training are the key elements that allow the machine to recognise postures, trajectories inside the kennel and patterns of movement that can be later labelled at convenience. The main innovation of the software is its ability to automatically cluster frequently observed temporal patterns of movement without any pre-set ethogram. Conversely, when common patterns are defined through training, a deviation from normal behaviour in time or between individuals could be assessed. The software accuracy in correctly detecting the dogs' behaviour was checked through a validation process. An automatic behaviour recognition system, independent from human subjectivity, could add scientific knowledge on animals' quality of life in confinement as well as saving time and resources. This 3D framework was designed to be invariant to the dog's shape and size and could be extended to farm, laboratory and zoo quadrupeds in artificial housing. The computer vision technique applied to this software is innovative in non-human animal behaviour science. Further improvements and validation are needed, and future applications and limitations are discussed.</p

A comparative perspective on the evolution of tamarin and marmoset social systems

Tamarins and marmosets (callitrichids) present an unusual opportunity for study of the determinants of primate social systems, because both the mating and infant care patterns of callitrichids are variable, even within individual populations. In this paper, I briefly describe three characteristics of callitrichid social systems that distinguish them from most other primates: extensive male parental care, helping by nonreproductive individuals, and variable mating patterns. I then discuss the evolution of these characteristics and of the frequent twinning exhibited by callitrichids. I suggest that an ancestor of modern callitrichids gave birth to a single offspring at a time, mated monogamously, and had significant paternal care. The idea that males of this ancestral form must have provided paternal care, even though only single infants were born, derives from a comparison of litter/mother weight ratios in modern primate species. Twinning perhaps then evolved because of a combination of dwarfing in the callitrichid lineage, leading to higher litter/mother weight ratios, and a high infant mortality rate, and because the extensive paternal care already present facilitated the raising of twins. I propose that the helping behavior of older offspring may have coevolved with twinning, because helpers would have increased the chances of survival of twins, and the presence of twins would have increased the benefits of helping. Finally, the high costs of raising twins and the variability of group compositions, especially the fact that some groups would not have had older offspring to serve as helpers, may have selected for facultative polyandry in saddle-back tamarins ( Saguinus fuscicollis ) and perhaps in other callitrichid species. Both helping and cooperative polyandry have been extensively studied in bird species, and I apply some of the conclusions of these studies to the discussion of the evolution of callitrichid social systems.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44556/1/10764_2005_Article_BF02193696.pd
