Canine obesity affects an estimated 40-60% of companion dogs and causes chronic pain, reduced lifespan, and diminished quality of life. Evidence-based weight management dramatically improves welfare outcomes.
Canine obesity represents one of the most common and preventable sources of chronic suffering in companion dogs. Excess weight causes mechanical stress on joints, worsens arthritis pain, reduces respiratory capacity, and increases risk of multiple serious diseases. Despite this, most owners of overweight dogs either do not recognize the problem or underestimate its severity. Veterinary reluctance to discuss obesity — fearing client offense — contributes to systematic underdiagnosis. Effective weight loss requires caloric restriction combined with exercise appropriate for the dog's current fitness level. Prescription weight-loss diets providing adequate nutrition at reduced calories outperform simply reducing portions of maintenance food. Regular weigh-ins at 2-4 week intervals maintain accountability. Some dogs — particularly Labrador Retrievers with the POMC gene variant — have physiological drivers of chronic hunger requiring careful management.
