Shelter dogs face the challenge of adapting to a kennel environment, making it crucial to monitor their welfare through behavioral and physiological parameters. In this study, we examined the use of a 3-axial accelerometer (Actigraph®) to assess nocturnal activity as a potential indicator of adaptability in shelter dogs during the first two weeks of their stay. We also collected urinary cortisol/creatinine ratio (UCCR), body weight, and behavior data to evaluate stress responses. A control group of pet dogs in homes, matched to the shelter dog group, was also monitored for comparison.

Findings:

Shelter dogs exhibited higher nocturnal activity and UCCRs compared to pet dogs, particularly during the initial shelter days.

Nocturnal activity and UCCRs decreased over time during the shelter stay.

Smaller dogs displayed higher nocturnal activity and UCCRs, with less autogrooming during the first nights.

Dogs without previous kennel experience had higher nocturnal activity and UCCRs, along with less body shaking.

Shelter dogs showed less body shaking during the first night, and the number of dogs displaying paw lifting decreased over time.

Age and sex had minimal effects on activity behaviors.

Shelter dogs experienced a significant loss of body weight after 12 days in the shelter.

Learning

Shelter dogs exhibited disrupted nocturnal resting patterns and stress responses compared to pet dogs. However, they seemed to partially adapt to the shelter environment after two weeks. The sensor-supported identification of nocturnal activity can serve as a valuable tool for welfare assessments in animal shelters.
