one more thing

Question
I also have him on z/d hills science food which is an allergy food.. . . no help. $31/8 lbs. . and doesn't help.

Answer
Hello again Wendy,
I know exactly how you feel.  I have a dog that has been battling ear infections for about a year and a half now and have tried about everything.  I have changed his food, used about every cleaning product they make, and have tried more medications than I can remember and am still treating him.  He is now on Predisone and its finally starting to work.  

Rather than the food you are using, you might just switch to a Lamb and Rice formula because dogs can easily become allergic to products with Chicken and Corn.  

Again, I hope this helps you.  Please feel free to contact me if you have other questions or concerns,
Kim
