Special Issue Information

Dear Colleagues,

In modern society, animals that are raised for food production or that live in contact with humans, are kept as pets, or are used in sporting events or other types of entertainment, or are dependent in some other way on human management may experience multiple acute or chronic stressors. Resilience, the capacity to overcome stress and adversity while maintaining normal physiological and psychological functioning, might buffer against individual psychophysiological stress responses and could be an important contributor to enhanced wellbeing. Animals’ physiological and behavioral responses to daily life stressors are mediated by endocrine responses that might have negative or positive effects on their welfare.

In order to enhance the quality of life of individual animals, regardless of their role in human society, welfare scientists have emphasized the need to track non-invasive biomarkers of their physiological, behavioral, and emotional health.

This Special Issue will focus on research or reviews investigating innovative and traditional approaches to assess hormonal activity related to stress response and resilience in the animal welfare field, with the aim to create a snapshot of the current state of the art.

The adverse health effects of both active and passive tobacco smoke have been well-known in humans for a long time. It is presumable that even pets, which intimately share the owner’s lifestyle, may be exposed to the same risks. This study aimed to detect and quantify cotinine (a metabolite of nicotine) in the serum and hair of dogs using a specific commercial ELISA immunoassay kit. A total of 32 dogs, 16 exposed and 16 unexposed to the owner’s smoke, were enrolled. The cotinine concentration was higher in the exposed than the unexposed group in both matrices (p < 0.001), with greater values in serum than in hair (p < 0.001). Exposed bitches had higher hair cotinine than male dogs (p < 0.001). Conversely, serum and fur cotinine concentrations were lower in female than male dogs of the unexposed group (p < 0.01). The exposure intensity, age, and weight of the dogs did not affect cotinine concentrations. A cut-off value of 2.78 ng/mL and 1.13 ng/mL cotinine concentration in serum and fur, respectively, was estimated to distinguish between the exposed and unexposed dogs. Cotinine was confirmed as a valuable marker of passive smoking also in dogs. Although owners do not perceive secondhand smoke as a risk for their dogs, greater awareness should be advisable, especially in pregnant animals. Full article
