Name one common sign of dental disease in pets.

Bad breath, also known as halitosis, is a common sign of dental disease in pets. This unpleasant odor often results from the accumulation of plaque and tartar on the teeth, which can lead to gum disease and infections in the mouth. When bacteria break down food particles and create a breeding ground for plaque, it can emit foul-smelling gases that contribute to bad breath. In pets with dental disease, the halitosis may become noticeably worse due to inflammation, infection, or the presence of decaying teeth or gum tissue.

While excessive barking, weight loss, and frequent urination can indicate a variety of health issues, they are not specific indicators of dental disease, making bad breath a more relevant sign in the context of diagnosing dental problems in animals. Therefore, recognizing bad breath in pets can prompt pet owners to seek veterinary attention for potential dental evaluation and treatment.
