Dental disease affects the vast majority of companion dogs and causes chronic pain that significantly impairs quality of life. Prevention and early treatment are the most impactful interventions for dog dental welfare.
Dental disease represents one of the most widespread and underrecognized welfare problems in companion dogs. The combination of high prevalence, pain that dogs rarely vocalize, and owner unawareness creates a situation where millions of dogs live with chronic oral pain that significantly reduces their quality of life. A dog with severe periodontal disease may eat normally out of strong food motivation despite significant pain — owners interpret continued eating as evidence that the dog is well. Signs of dental pain include head-shy behavior, dropping food, preference for soft food, and reduced interest in chewing. The most effective prevention is daily toothbrushing, which most dogs will accept if introduced with positive reinforcement from puppyhood. Annual veterinary dental examinations allow early detection and intervention before disease becomes severe. The cost and anesthetic risk of professional cleaning, while real, are far outweighed by the welfare benefit of eliminating chronic pain.
