my girl is so different.. I have to work to keep weight on her.. She is eating about a 3/4 of a natural canned food plus a bit of dry a day. ppl still tell me she is skinny, so then I let them hold her leash for about a min before their jaws drop at her strength… must be all the mountain climbing.. cause she pulls like an Ox.
My girl Rio is like this. She is all muscle, high metabolism. We call her "super model thin". She eats plenty. She gets 1/2-3/4 of a can of wet food plus 1/2 a cup of dry. In the spring when she is racing, she eats a full can plus dry. This is why she loves her coats, she has no extra padding to keep her warm.
