Welcome to Pet Talk!

I'm sorry that you and Melinda are going through this. Constant ear infections are no fun. Thank you for working so hard to try and mend things for her.

My cat Bobby had the allergy test and I gave him the shots here at home for a year. After that he seemed fine. It's now bee 6 years with no recurrence. But he was scratching all over his body, till he bled, not ear infections.

Is there some way to do prevention? I had a dog who constantly developed ear infections. I used OtiClens three times a week for the 6 years she lived with me (Lacey was a rescue) and that solved the problem. We never did sort out what exactly was the underlying cause. Might this sort of thing be of help for Melinda? The fact that the convenia brings relief suggests she gets a bacterial infection (not a yeast infection) so this may guide you / your vet as to which sort of ear cleaner to use.
