Abstract

Behavior and plasma cortisol levels were examined in puppies and juvenile/adult dogs admitted to a public animal shelter. A behavioral test was developed to assess the responses of the dogs to novel or threatening conditions. Factor analysis of the behavioral responses of 166 dogs on day 3 in the shelter yielded six factors (locomotor activity, flight, sociability, timidity, solicitation, and wariness) that accounted for 68% of the total variance. Among those dogs remaining in the shelter for 9 days, plasma cortisol levels declined from day 2 to 9. Cortisol levels were weakly related to factor scores. In order to explore the relation of measures in the shelter to later behavior, questionnaires assessing problem behaviors were mailed to new owners of dogs 2 weeks and 6 months following adoption. Among puppies, wariness scores were negatively correlated with behavior problems at 2 weeks and cortisol levels were negatively correlated with behavior problems at 6 months. These results suggest how measures of behavior and endocrine activity obtained in shelters might prove useful for screening dogs for adoption or targeting dogs for behavioral intervention.

Abstract

Environmental enrichment may improve the quality of life of captive animals by altering the environment of animals so that they are able to perform more of the behavior that is within the range of the animal's species-specific repertoire. When enrichment is introduced into an animal's environment, it is important to evaluate the effect of the enrichment program and to assess whether the animal continues to use the enrichment in the long-term. Groups of mice were housed under either standard or enriched conditions for several weeks. Nesting material which was highly preferred in previous studies was used as enrichment. During the period of differential housing several behavioral parameters (behavioral tests and handling) and physiological parameters (urine and plasma corticosterone, food and water intake, body and adrenal weight) were monitored to determine the impact of environmental enrichment. Observations were made to determine whether or not the mice continued to use the enrichment. The results indicated that throughout the study all mice used the nesting material to build nests and that mice from enriched conditions weighed more than mice housed under standard conditions, although the latter consumed more food. No major differences for behavioral and physiological parameters were found between the groups of mice housed under different conditions. Therefore it is not likely that supply of nesting material will jeopardize the outcome of experiments.

Abstract

Because of the pathogenic effects of chronic stress exposure, it is important to identify factors, such as effective coping strategies, that mitigate stress-induced pathology. Of interest in the present study was the consistency of behavioral responses across a diverse array of stressors. Sixteen male and 16 female Long-Evans rats were assigned to either a stress or control group. The stressed animals were subsequently exposed to a battery of ecologically relevant stressors (e.g., predator odor, novel stimuli, and immunological challenge) to determine trends in coping strategies. Blood was collected for corticosterone (CORT) assay and brains were harvested for assessment of fos immunoreactivity in the paraventricular hypothalamus (PVH) and central amygdala (CEA) following exposure to the final stressor of fox urine. A correlational analysis indicated that certain response strategies (e.g., latency to respond in different stress tests such as the open-field and novel item tests) persist across several behavioral tests, especially those tests involving exploratory components. A subsequent principal component factor analysis revealed the following four components: initiative to explore, low reactivity, variable reactivity, and high reactivity. Females exhibited higher recovery CORT levels than males; however, sex only affected one behavioral response measure (i.e., females demonstrated more attempts to climb the wall in the forced-swim test than their male counterparts). In conclusion, these results support the importance and prevalence of initiative to explore as a common factor in many stress tests; additionally, the principal component analysis indicated that physiological correlates of stress are more closely associated with more challenging environments and stimuli such as forced swimming, immunological challenges, and exposure to predator odors.

Abstract

The relationship between domestic dogs and humans represents a unique example of an interspecific relationship. For this and other reasons, there has been a substantial increase in research on dogs. This Special Issue entitled “Dog Behaviour, Physiology and Welfare” collects important information ranging from basic to applied ethology, dealing with canine endocrinology (prolactin, vasopressin, thyroid hormones), physiology (visual perception), welfare (in shelters and zoos), as well as the context of working dogs (service dogs, co-therapist dogs, herding dogs) and the dog–wolf comparison. All the papers are open access and can be read at https://www.mdpi.com/journal/animals/special_issues/Dog_Behavior
