Spanky is still having major trouble with is ears. The vet convinced me that at 8 years old, it is best not to mess around trying different foods without some basis. She gave him an allergy blood test (just testing for foods) that she is mailing away. We will have results in about 10 days. In the meantime, he is eating the dry version of Z/D Prescription Diet. She is also continuing the Simplicef antibiotic. This was an expensive day and we are hoping for the best for Spanky!
