A common sign of rabies in animals is changes in behavior. This can manifest in various ways, such as increased aggression, fearfulness, or unusual interactions with humans or other animals. For instance, an animal that is typically shy may become overly friendly, or a normally calm pet might display unexplained aggression. As rabies progresses, neurological symptoms may develop, leading to confusion, disorientation, and an overall change in demeanor. These behavioral changes occur due to the virus affecting the animal's central nervous system, causing alterations in its normal behavior patterns.

Other choices do not accurately reflect common signs of rabies. For example, weight gain and increased appetite are typically associated with health behaviors unrelated to rabies. Excessive barking may indicate a variety of conditions or behavioral issues but is not specific to rabies. Thus, changes in behavior stand out as the most significant and telling sign of rabies in animals.
