If the skin looks healthy then you don't need medicated shampoo. Look at the skin all over the body for dry spots or redness. If the skin looks fine then run a flea comb through just to make sure no fleas have jumped on. A dog with a flea allergy with have itching even with one lonely flea on the body.
Sometimes a food allergy can cause itching. Does your dog just scratch in one particular place? Does he chew also or just scratch? Don't use medicated shampoo unless there is something you can see on the skin. That is just treating the symptoms and not really dealing with the actual cause of the problem. |
