Hi, my 9 year old cocker spaniel has had ear infections almost constantly in the 4 years I've had him. For the majority of this time I fed him natural balance LID bison or merrick grain free buffalo. After another round of infections, the vet suggested switching him to Hills Z/D. He has been on this for 3.5-4 months now and has eaten nothing but this food. He still has had multiple infections during this time and was treated for all of them. The old food should be out of his system now so with the current infection, can I assume he does not have a food allergy? Or should I still try and switch him to a rare protein i.e.: duck or kangaroo? Also wondering what sort of environmental allergies are common with cocker spaniel and if that should be my next step to combat this. Thanks for any and all advice!
