My rough collie puppy is too short. How can I help him grow?

Updated on September 23rd, 2025

Pet's info: Dog | Rough Collie | Male | neutered | 8 months and 18 days old | 32.2 lbs

Trusty is a full blooded rough collie, I feed him Purina Pro Plan Focus Puppy lamb and rice, but I'm worried about Trusty's size. I exercise him everyday for at least 20 mins. I feel like he's too short. Is there anything I can do for him to help him grow.

Trusty is a beautiful boy! The best thing you can for Trusty which is feeding a high quality dog food. Trusty does need to eat a large breed puppy formula. Stick with ProPlan or Royal Canin. I'm not sure the diet you are feeding is the correct one. It will say on the bag if it is intended for large breed puppies. He should eat this until he is 12 months old.
Growth is genetic. A dog will not be any bigger than it's genes allow for. Growth in large breed dogs also needs to be slow to help prevent orthopedic conditions like dysplasia. Additionally, he will continue to grow (in height) until he is 12 months old. He will begin to fill out from 12-18 months of age (roughly). I hope this helps and please feel free to post any additional questions.
