What is a sign of pain in animals that owners should be aware of?

Withdrawal and decreased activity in animals are widely recognized signs that indicate they may be experiencing pain. When an animal is in discomfort, it often seeks to minimize its movement and interaction with its environment. This behavior can manifest as reduced playfulness, reluctance to engage with family members or other pets, and an overall lack of interest in normal activities.

In contrast, the other options suggest behaviors typically associated with comfort or normalcy. Increased social interaction could indicate that a pet is feeling well and has no pain. An increased appetite may imply that the animal does not have any distress that would typically suppress eating, while enhancements in grooming behavior often suggest a sense of well-being and normal health. Therefore, recognizing withdrawal and decreased activity as signs of pain is crucial for pet owners, allowing them to seek appropriate veterinary care when their animal may be in distress.
