How obesity affects dog welfare and evidence-based approaches to prevention and treatment.
Dog obesity is a welfare crisis driven primarily by food reward culture and underestimation of caloric needs. Dogs who are fed too much for their activity level and metabolic rate gain weight gradually in ways that owners normalize because the change is slow. The welfare consequences are serious and compounding: excess weight accelerates joint damage, impairs breathing, strains the cardiovascular system, and reduces a dog's capacity to participate in the activities that provide quality of life. Weight loss in dogs requires consistency over months, which challenges many owners. The most effective approach combines measured feeding, reduced treat calories, and increased activity — all achievable with veterinary guidance and owner commitment.
