Hi, why is my lab not growing in size !? His parents are tall and have strong builds, max is smallest amongst the litter even tho the breeder said he's the pick of the litter. He's literally the same size when we brought him in 3 months ago. His weight is 15kg. You can compare the builds(pic below) of his father and him. I feed him exactly like the vet suggested. He has no sign or worms as well. When will he grow big and strong like I know he's still a pup but i literally observe no difference!?

Like people, dogs can grow at different rates and experience growth spurts. I would expect Max to be of a similar size and build as his father.
To help ensure he has adequate nutrition to grow double check the feeding guidelines in his dog food. I would also consider adding extra protein to his regular puppy food diet.
Boneless boiled chicken breast and extra lean beef can both be good additions and used as treats.
