My healthy dog is underweight. What are the best weight gain foods?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 3 years and 3 months old | 70 lbs

Bruno has severely lost weight in the past couple months to the point his bones are easily felt. Vet gave him a clean bill of health. He eats twice a day 2 cups each time. And he just turned 3. Vet told me to look into a weight gainer product. What are your recommendations?

Thank you for submitting your question regarding Bruno. If you veterinarian has found him to be healthy, then I recommend feeding a high energy food. Purina ProPlan Performance diet is formulated for athletic dogs. This or something similar should help him gain and maintain weight. I hope this information helps!
