The only thing I could think of would be shampoo. Because when she was on royal canin for her food, she itched like that, and I switched to Innova and it immediately stopped. Now she's at it again, so I doubt it's her food. I don't give her treats that she hasn't been given before, mostly fruits and greenies.Vet said that ticks are in highly wooded areas like camping sites, not grass or gardens or anything. I checked for fleas, nothing...ARGHHHH
