Key Facts

Welfare Considerations

Companion animal obesity represents a significant and largely preventable welfare crisis. Overweight and obese pets experience chronic joint pain, reduced exercise tolerance, heat stress, and increased risk of metabolic disease. Their lifespans are significantly shortened. The root cause is almost always excessive caloric intake relative to output — often driven by owners who express affection through food, misread hunger signals, or are not shown how to assess their pet body condition. Evidence-based weight management requires accurate portion control using a measured diet, regular body condition assessment, adequate exercise, and engagement with a veterinary nutrition professional for obese individuals.
