Dental disease is the most common health problem in dogs yet remains severely undertreated. Understanding its welfare impact motivates the preventive care that can save years of pain for companion dogs.
Canine dental disease welfare parallels feline dental disease in its hidden nature and significant welfare impact. Dogs continue eating with painful, infected teeth because the drive to eat is strong and showing weakness is evolutionarily disadvantageous. The transformation in behavior after successful dental treatment — increased play behavior, improved appetite, greater engagement with family — reveals the pain burden previously carried silently. Dental disease causes bacteria to enter the bloodstream from inflamed gums, contributing to systemic disease including cardiac valvular disease, kidney disease, and other organ damage. The preventive calculus is clear — regular veterinary dental assessment and professional cleaning prevents more suffering than it causes, at lower long-term cost than treating advanced disease.
