What is a key sign that a dog may need physical rehabilitation?

A key sign that a dog may need physical rehabilitation is a decrease in activity. This reduction can signal underlying pain, injury, or mobility issues affecting the dog's willingness to engage in normal behaviors. When dogs are not as active as they once were, it may be related to musculoskeletal problems, joint pain, or recovery from surgery, all of which can benefit from physical rehabilitation to restore mobility, strengthen muscles, and alleviate discomfort.

While continuous barking, excessive scratching, and overeating might indicate other health or behavioral issues, they do not directly relate to the physical capabilities or the need for rehabilitation of a dog's body. Decreased activity is specifically associated with the need to assess physical function and address any potential injuries or conditions that impair movement.
