Our puppy Jagger is going on 5 months old. About a week ago we changed his diet from 3 bowls a day down to 2. During this time we noticed that he leaves his food sitting and picks at it sparingly. I am just curious if this is due to his teething phase or is he starting to self regulate as I've read elswhere? He does manage to eat it all, it just seems to take him some time.
