Many dogs suffer from dental problems after the age of three — including tartar, periodontal disease, and inflammation of the tissue around the teeth. These issues seriously affect a dog's health and well-being, often causing pain or a refusal to eat. Dental problems can be recognized by foul breath, dark deposits on the teeth, and difficulty chewing. Fortunately, this can be prevented with good dental care. A proactive approach to your dog's oral health helps keep their teeth clean, their breath fresh, and their tail wagging for years to come.
