Which of the following is often a sign of stress in pets?

Excessive grooming is often recognized as a significant sign of stress in pets. When animals are stressed or anxious, they may engage in grooming behaviors as a coping mechanism. This can manifest as licking or chewing on their fur, which, in some cases, can lead to hair loss or skin irritation. The behavior may serve to soothe their nerves or as an outlet for pent-up energy or frustration.

In contrast, increased appetite, calm demeanor, and playfulness typically do not indicate stress and may instead suggest a relaxed state or contentment in pets. Understanding these indicators of stress is crucial for pet owners and veterinary professionals to provide necessary support and interventions for animal well-being. Recognizing excessive grooming is vital for addressing and alleviating the underlying causes of stress in pets.
