First post here.
I feed my 6 months German Shepherd Orijens Puppy Large.
I am very happy with it as the dog is healthy energetic and has a beautiful coat. The problem is the amount. I am already giving him above the recommended amount and he is generally stressed out in hunger. His vet also says he seems a little thin…
Should I feed him more or should I complement with some homemade food, and what would be the best feeding options?

Thanks.
