Stanley is just over 4 months old now and we are feeding him the Wellness Just for Puppy dry dog food. However, the package suggests we feed him 2 1/2 cups a day. That seems a bit high to me. He's already almost 15 lbs. The vet said he is fine and I can still feel his ribs, etc. But how much do you think is good to feed a 17 week old puppy? I'm especially curious for those of you who fed your puppies the Wellness kibble. TIA!!
