Obesity affects over 50% of pet dogs in many Western countries. Excess weight causes chronic pain, reduces quality of life, and shortens lifespan. Prevention and management are fundamental welfare responsibilities.
Dog obesity is a welfare crisis that is largely invisible to owners because excess weight accumulates gradually and dogs continue behaving relatively normally until the condition is advanced. Obese dogs experience chronic pain from joint loading, exercise intolerance, respiratory difficulties, and reduced ability to perform normal dog behaviors including running, playing, and exploring. The emotional and psychological welfare of dogs is affected by their reduced capacity for joyful physical activity. Veterinarians play a critical role in delivering honest body condition assessment and weight management guidance, but owner receptiveness is often limited by the normalization of overweight dogs and the powerful emotional bond between food provision and affection. Public health messaging that reframes food restriction as an act of love rather than deprivation is an important welfare communication priority.
