I'm thinking of adopting a 5 yr old Australian Shephard....great dog....only he's got some sort of allergy that he takes constant antibitotics for....his nose is all read & raw looking. His current owner had all his vet records, and biopsies, etc show no cancer or anything, just some allergy. Is this normal? Will it get worse? Wondering what I should expect. Is this a serious issue?
Thanks in advance for any info you can provide.
