What behavior might indicate a pet is in pain?

Increased vocalization is a strong indicator that a pet may be experiencing pain. Pets often communicate their discomfort through sounds such as whining, yelping, or excessive meowing or barking. These vocalizations can indicate distress and are a way for animals to express that they are not feeling well.

Other behaviors, such as grooming more frequently, might suggest anxiety or stress rather than pain, as pets sometimes groom themselves more when they are nervous. Faster eating can also be associated with other factors, such as excitement or competition for food, rather than indicating pain. Increased playfulness typically suggests that a pet is feeling well and comfortable, which is contrary to the signs of pain. Thus, changes in vocalization are the most direct way pets express that something is wrong, making it a key behavior for identifying pain.
