The royal canin bag says to feed 5 1/2 cups of food a day, that is alot!!
is this recommended?
I feed my 5 month old pup 4.5 cups of food. She is plump, yet still lean, if that makes any sense :P
This was her at about 4.5 months old and you can see she is not fat, but she is healthy.
And the food I am feeding states 3-3.5 cups for a pup her age. So you also have to take in consideration each dog will be different, type of dog, energy level, etc.
