What is a common sign of dental disease in pets?

Foul breath, or halitosis, is a common sign of dental disease in pets. This occurs due to the buildup of plaque and tartar on the teeth, which can lead to gingivitis, periodontal disease, and other oral health issues. As the bacteria in the mouth proliferate, they produce sulfur compounds that contribute to bad breath. This symptom can often be one of the earliest indicators that a pet may be experiencing dental problems, prompting owners to seek veterinary care for proper evaluation and treatment.

In contrast, while increased appetite, excessive sleeping, and frequent barking can indicate other health issues or behavioral concerns, they are not specifically linked to dental disease. Increased appetite might suggest a different underlying condition such as hyperthyroidism or diabetes, excessive sleeping could indicate a range of illnesses including pain or lethargy, and frequent barking may relate more to anxiety, boredom, or other behavioral issues rather than dental health. Therefore, foul breath stands out as a clear and direct sign of potential dental problems in pets.
