I have a one year old mutt (rat terrier, min-pin, bischon). She has what I think is an abscess on her chin that popped and drained. I am irrigating it with a saline solution the best I can and putting a little neosporin on it. I am trying to avoid a trip to the vet as I do not have the cash to pay for a trip there. Is there anything else I can do to help her?
