Hi I wondered if anyone could help Georgie my 12 week old puppy has been scratching for weeks and sometimes cries out . I have spoken to the vet and she has treated her with advocate which treats fleas and lots of different mites. The vet can't see anything on her skin. I have also changed her diet to pro plan sensitive salmon and rice. I feel so sorry for her and really want to sort this problem out. Any advice would be great. Thanks .
