Abstract:
... Studies regarding the neoplastic infiltration of the skin overlying canine subcutaneous soft tissue sarcoma (sSTS) are lacking. In case of the absence of tumor infiltration, there would be the possibility of leaving this unaffected skin in place, thus simplifying surgery. The aim of the study was to investigate whether the skin overlying sSTSs is infiltrated by neoplastic cells. Dogs with sSTSs tr ...

Abstract:
... Two explosive detection dogs were deployed to search a suspicious bag, and failed to detect 13 kg of explosive within. The aim of this research was to further evaluate this incident. First, dog teams (N = 7) searched four bags in a similar scenario. One bag contained the same 13 kg of explosive, two bags were blanks, and the other contained the training sample that the agency routinely used for tr ...

Abstract:
... Assessments for behavioral inhibition in pet dogs that can rapidly detect age-related cognitive deficits (ARCD) using inexpensive and accessible materials may aid in diagnosing canine dementia and may facilitate translational research on Alzheimer’s disease in humans. In this study, we designed and deployed a spatial serial reversal learning test in which 80 pet dogs were required to learn which o ...

Abstract:
... Pacemakers use heart rate histograms (% beats) and sensor indicated rate histograms (% time) to illustrate rate distributions. When programmed to the rate adaptive modes, these data are used to determine the appropriateness of rate response to activity. These histograms are generated from instantaneous heart rate calculations. In humans, such data are compared to known histographic rate profiles. ...

Abstract:
... Anxiety tends to aggregate in families, and families increasingly include companion animals, such as dogs. Based on previous research pointing to a ‘personality fit’ between humans and their companion dogs, this study explored the potential association between owners’ trait anxiety and dogs’ fear and anxiety-related behavior problems, while also testing for mediating and moderating factors. Two hy ...

Abstract:
... Significant numbers of dogs are relinquished to shelters each year, impacting dogs, owners, and communities. Attitudes surrounding relinquishment may guide how a dog owner responds to situations such as behavioral problems or financial difficulties and may also influence what owners disclose to shelters at the time of surrender. However, no previous studies have examined attitudes toward relinquis ...

Abstract:
... Primordial germ cells (PGCs) have been described as precursors of gametes and provide a connection within generations, passing on the genome to the next generation. Failures in the formation of gametes/germ cells can compromise the maintenance and conservation of species. Most of the studies with PGCs have been carried out in mice, but this species is not always the best study model when transposi ...

Abstract:
... Due to the lack of unequivocal scientific evidence, gonadectomy’s effects on dogs’ behavior are still debated. Since veterinarians differ in their opinion, there may be considerable diversity in the advice received by owners. This study aimed to evaluate the effects of gonadectomy on dog behavior across time. Ninety-six dog owners (48 control dogs and 48 experimental dogs) were interviewed twice ( ...

Abstract:
... There is a consensus that humans, rodents, and primates process odor mixtures configurally: that is, the mixture is perceived as a unique whole and not as a collection of its different components. However, it is commonly believed by dog trainers that dogs can analyze mixtures and break them down into their individual components: that is, that they process odor mixtures analytically. There is, howe ...

Abstract:
... Animal shelters and rescues are typically judged on their live release rates. The number of companion animals adopted and then returned to the shelter is not as frequently considered. Matching programs are implemented to reduce the chances that a companion animal will be returned after adoption by assuring the best possible “match” between adopter needs, wants, and lifestyles, and the behaviors an ...
