Dog obesity is the most common preventable welfare problem in companion animals, causing chronic pain, reduced lifespan, and significantly lower quality of life.
Dog obesity causes significant, ongoing welfare harm that is often invisible to owners normalised to heavier dogs. Obese dogs carry excess weight on joints not designed for it, causing arthritis pain with every movement. Respiratory compromise limits exercise, causing heat intolerance and breathlessness. Reduced mobility prevents dogs from performing the exercise and play behaviours fundamental to positive welfare. Insulin resistance and diabetes cause polydipsia, polyuria, and metabolic distress. The emotional component — owners using food as an expression of love — creates a difficult welfare paradox where loving behaviour causes harm. Veterinary body condition scoring education and non-food bonding activities are the most effective interventions.
