I notice that my 6 month old puppy scratches a bit, and also rolls around on the carpet/grass, possibly getting itch relief.I don't think she has fleas, so I've been wondering if it's a bit of a skin issue. She's 3/4 poodle. Has anyone got any advice for this? I'm raw feeding her, I was wondering if adding oil to her food could help, also if there is a shampoo that could help? I don't bath her often.
