$700 vet bill, "solved" issue, now it's back - help

...I'm guessing the reaction wouldn't be too far from the injection site?

I would think so, or at the very least, on the same side of the body (assuming it may have migrated some). If this latest peeling wound isn't increasing or spreading, I'd try to stay optimistic, but truly, there's no telling with all that this BP has been thru. Antibiotic injections, while necessary, aren't without risks...I would keep asking & researching...it might not only be Baytril that can cause such side effects...or it may be because it was used in combination? All I know is
that over many years, snakes & drugs don't mix very well; yes, sometimes you have to use them, but always I try to minimize & concentrate on natural ways.
