Pet obesity has become an epidemic affecting over 50% of companion cats and dogs in developed countries, causing chronic pain, reduced lifespan, and diminished quality of life in millions of animals.
Obesity causes measurable suffering through increased arthritis pain, reduced respiratory capacity, exercise intolerance, and heat stress. The welfare impact is often invisible to owners because affected animals adapt their behavior to their limitations rather than expressing obvious distress. A previously active dog that now refuses walks or climbs stairs slowly is experiencing genuine pain and physical limitation, not simply aging. Successful weight loss in overweight pets produces dramatic welfare improvements — increased playfulness, better mobility, and apparent improved mood. The challenge is owner motivation: many owners associate food with love and find weight restriction emotionally difficult. Veterinary coaching framing weight management as welfare improvement rather than deprivation changes this dynamic.
