I would guess it's probably detoxing. Delilah was a bit gassy when I first switched her..she's still gassy but not nearly as bad as with kibble, haha.
I never noticed a bad change in the way her fur smelled though. She actually smells better, I think. Most people say that raw makes your dog not smell like a dog, LOL. I think raw has made her coat even shinier and it's so soft. I also bathe her once a week. I'm a dog groomer and I can't stand her looking bad, LOL.
Could very well possibly be from nuvet not wanting her bathed too...I can imagine she could get smelly if she's oily?
