Sasha has been itching since the day after we brought her home. The vet says she has no parasites. She gets bathed with water only now. Her puppy pen, the bathroom, gets has had all bedding removed and we rinse the floor after washing it. Her skin was dry and a bit irritated but she is silky smooth and her coat is gleaming now... but she still itches. She's on a limited ingredient homemade diet of just wild deer meat (what her "breeder" weaned her onto). I've been practically slamming my head against a brick wall trying to figure out what she's reacting to. From the day I got her I have used peanut butter treats to train her. Have you ever heard of a dog allergic to peanut butter? I'm going to remove it from her diet and see how it goes.
