I was glad to see that other people are sharing the same concerns that I have. My little 1yr old Zoe seems to be chewing on her feet alot with scratching behind her head as well. I briefly discussed it with my vet and he said that I would have to take her off all treats and other food stuffs and give her only her dog food to see if it was allergy or not. I've tried her on other foods but that was mainly because I didn't think she was eating enough of her dry Royal Canin. I do notice though that bathing in between groomings and not putting her sweaters on all the time helps to some extent with the itching. I'm really at a loss though and my vet wasn't much help.
