Just saw the vet for the first time today, she says my puppy was of normal weight. that's a relief. but i'm still concerned about "development" issues since i guess she was (if ever) malnutrition for 2 months??/ :( Vet told me just follow the instructions on the packaging (on this pet food my pup's in now = Vitality) .. i don't remember anymore the first pet food i used (1st two months with her) and i certainly didnt read the label on that one, i just went w/ a suggestion from the pet shop's staff (2tbsp x 2/day)
