My dog's paw pad is red and swollen. This has happened once before and the vet prescribed steroids.

I no longer want steroids for my dog because of another experience where she almost died.

Is there anything I can do to help this heal?

What can I put on it? (Neosporin?, wash it?)

It has been very snowy and icy here and I think that irritated the paw pad or that she got into salt perhaps on the driveways in the neighorborhood.
