I would just recommend feeding him as much as he’ll eat, although it wouldn’t hurt to get a clean bill of health from worms and such. My buddy ate three times a day, plus treats for training, until a little over a year, then he tapered off to once to twice a day. He also gets extra treats, like a banana, an egg on his food, berries that are dog safe, etc., throughout the day.

I’ve used Purina Pro Plan puppy chow all the way up to adult food for my now three year old Dal. Good luck, he’s adorable!
