Chihuahuas

hi my dog rocky has like dry ear on the tip they are almost cracked i've went to vet buttheir meds don't seem to work and rocky is always scratching at them i Thoughts of mites but no not fleas i'm clueless does anytone think sunburned?

Is he broken out anywhere else? Could be a food allergy or even a thyroid problem (cause skin conditions). I would let the vet know that their meds aren't working. You could also try putting a little neosporin on them just to keep them moist.

Most likely not ear mites they are inside of the ear and the dog will scratch and shake his head.

Keep us in the loop.

Good luck.
