I don't know about other raw fed dogs, but mine definately are. Cowboy has become very lean and Blondie hasn't ever had an ounce of fat on her (she actually looks ripped through her fur). At first I was worried about the fact that Cowboy lost his "old age" fat pads right above his hips, but now I've come to the conclusion that he can do without that fat as long as he isn't starved (yeah right, like that will ever happen around here

). I realize that many dogs in the US are overweight in varying degrees, and I guess Cowboy was one of them.
I can't believe that it only took a week to notice the change on Lily, wow.
I had to look, but I found a picture that shows her musculature.

She is very hard to the touch all over.
