My dog is extremely itchy. He rubs his face and body constantly all over the carpet, side of sofa and anywhere he can really. We have seen the vet a few times who has put him on medication. This helps a little bit but seems to make him sleepy. Is there any natural way to help with this? Does anyone know of any particular food that could help? I looked in the pet shop but there are tons of hypoallergenic foods so if anyone has any experience of one that works I would be very grateful!
