Why is my active puppy so thin and not gaining weight?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | 4 months and 11 days old | 10 lbs

My pet is hyperactive but he is very thin. His diet is more than sufficient, but still, he is very thin. We usually play with him through games like that of fetch and running. We have trained him to sit, shake hand and to stay. If this is an issue, kindly suggest me a way to have him in becoming fatty. Thank You.

Feed more food! Make sure Simba gets a good quality, commercially prepared puppy food (not food for active adults). Start by feeding the recommendation labeled on the bag, but if he wants more he can have more. Also, make sure that Simba doesn't have diarrhea and that he has been appropriately dewormed.
