What is pacing a sign of in older dogs?

Pacing is a sign of anxiety, liver abnormalities, Cushing's disease, cognitive dysfunction or brain tumors in older dogs, states The Nest. All these conditions require a professional, veterinary diagnosis. However, many of them only need simple treatments, such as a change in diet or exercise.

An older dog pacing can be a sign of a serious illness or condition, and seeking immediate veterinary care is the best course of action to avoid deadly complications, according to The Nest.

Keep records and take videos of an older dog's pacing, says The Nest. These recordings prove invaluable in the diagnostic and treatment process for the dog's condition.
