Food Allergies??        I have an 8 year old yorkie that licks his paws constantly.  He also has really pink skin, and has some thinning hair.  The vet thinks it could be a food allergy.  I currently feed him purina EN, which is a prescrption food for dogs with stomach problems.  I think he needs to be switched to a low allergy can food.  Can someone reccomend one I could buy.     |
