Help! I have a 1.5 year old shih-poo. She is a terrible scratcher. Year long. Trying the restricted diet but it is too early to tell. She scratchs her face to the point of hair loss & sores. Her ears smell a little funky. The hair on her lips and nose is almost gone and her lips are swollen and puffy. Vet thinks because it seems so localized, that it may be food allergies. What do you think?
