Would anyone be able to let me know how much James Wellbeloved kibble a 6 month lab pup should be getting, have asked the vet multiple times and she says to go from the back of the packet but that suggests 390g a day which seems like a tiny amount for a growing puppy to me. Am I being silly or should she be fed more? We also add either some chicken or other meat and sometimes some vegetables to her kibble if that needs to be taken into account
