Obesity in dogs and cats is a welfare crisis affecting an estimated 50-60% of companion animals in developed countries, with evidence-based dietary and exercise interventions able to dramatically improve health and welfare outcomes.
Companion animal obesity causes chronic welfare harm through reduced mobility, chronic pain from musculoskeletal stress, metabolic disease, and reduced quality and length of life. Despite being the most common health problem in companion animals, it is also one of the most normalized - owners often do not recognize overweight animals as overweight. Veterinarians face communication challenges in discussing weight with owners who may interpret obesity observations as criticism. Effective intervention requires honest weight assessment, calorically controlled feeding, regular weigh-ins, and sustained owner commitment over months. The welfare benefit of achieving and maintaining lean body condition is substantial and measurable in improved mobility, reduced pain, and extended healthy lifespan.
