I'm struggling with how much to feed my 9 month puppy. He's a Rottweiler, Shepherd, Pitt mix. At our vet's suggestion we switched him over to the adult version of our dog food (Taste of the Wild). The issue there is that it obviously doesn't tell us how much food he needs (plus those are just guidelines). He's currently eating about 5 cups a day but some days in the evening it seems like he's starving. He rarely demand barks but when he's hungry he'll go stick his nose in his bowl and bark at us. He typically plays with his doggy friends for 1-1.5 hours a day so he's pretty active. I know that Rotts can be kind of prone to being tubby and I want to be as easy on his joints as I can be. Anyone have any recommendations for adjusting food quantities up/down for a growing puppy? He's 72lbs right now. If you want to see what he looks like I posted an introductory thread over on the intro forum.
