I agree with Missi, I would go by the way the dog looks. That is why I was so concerned about Rex. He shows way too much ribs, actually every one of them and deeply too. He just weighed in at 56.60 lbs, but I think for his build he needs about another 5 or more lbs. He is over 2 years old already and would think he would start filling out more now.
I am also wondering if Rex could also have an extremely large rib frame. It really hangs low, LOL.... I don't know what to think of this dog anymore, LOL. He is driving me crazy
Rex always is ravenous too. I give him 1 1/2 pounds of meat a day plus rice plus The Honest Kitchen. I just also started giving him snacks of cottage cheese, not to mention all the bananas pieces he gets when he comes inside from potty, LOL.
