Hello once again. It seems to be that my puppy is scratching the back of her front legs with her rear legs and she also nibbles on her hind legs. She is developing hairless spots that look like dry skin. Ive talked to multiple people and everyone says its either food alergies or dry skin. Well since we just got her on new food (grain free earthborn holistic) i cannot determine if it is a food allergy or dry skin.... Is there a way to determine what the cause of itching is... We just did the oatmeal shampoo and conditioning and she is still itching like crazy.... I feel terrible at the fact that she is possibly miserable..
