Is there anything you can put on an open sore on your dog to help it heal & stop itching?

I am fed up with the Vet.

My dog has skin allergies. I bathe her with special oatmeal soap. It helps a little.

Yet my poor baby keeps getting areas on her body that drive her crazy and she won't stop biting that area.

I take her to the vet. It's always the same thing. Give her benadryl, here's some antibiotics, - that will be $75... it's a never ending circus, I'm back again within a month.
She just finished a round of antibiotics, and obviously they didn't help. I can't say if the Benadryl helps because she is still biting at the area.

There has to be some kind of lotion or something to put on it. Just like we use neosporin - except for dogs.

It breaks my heart, and I feel so bad because it makes ME crazy watching her that I snapped at her earlier to stop. :(

Hoping that someone knows of something that will soothe her skin & make her stop tearing herself to pieces.
