Pet obesity is an epidemic affecting over half of dogs and cats in many countries, causing chronic pain, reduced mobility, and shortened lifespan.
Pet obesity reduces welfare through multiple pathways: joint pain from excess weight bearing, reduced mobility, difficulty breathing, heat intolerance, and metabolic disease. Many obese pets show behavioral changes — decreased play, reluctance to exercise, irritability — that indicate chronic discomfort. The welfare impact is significant and largely preventable. However, owners often view feeding as an expression of love, and recognizing obesity in a beloved pet can feel like an accusation. Veterinary practices that normalize weight discussions and offer structured management programs show the best welfare outcomes.
