Rickie has 2 black small mole-like bumps - 1/4 inch or less in diameter, one on his bum, one on his chest, other side. It was needle-biopsied a couple of weeks ago and the cells came back "consistent with a cyst" but I don't like the look of it or the fact that he has two, so they are going to come off.
It's too soon to say about recurring infections, but to date he doesn't have any sort of pattern / ongoing problem that way.
Rickie was on Antirobe for 18 days and also on Baytril for the first 4 of those days (emergency clinic put him on both for his foot, my regular clinic discontinued the Baytril). He finished the Antirobe on Thursday. The hair loss developed while Rickie was still on antibiotics.
I was away for 5 days and noticed the hair loss when I returned on Monday evening - the area has doubled or more in size since then. I thought at first it was licking but surprisingly (to me) it doesn't seem to bother him. My husband worked from home while I was away and I have been absent before without issue, so I don't think it's stress-related.
The foot infection was very bad (it went from no outward sign in the AM to swelling heading up the leg and toes leaking blood within 15h) and the toe where it seems to have started eventually lost skin on each side and the black pad tissue on the bottom. That is still healing though it looks much better.
It is the aggressiveness of that infection that makes me wonder if this is somehow related. It will be very interesting to see what the tests on Monday show. (The foot infection wasn't cultured - the foot was so swollen and sore the vet didn't want to stick a needle into it.)
It will be very interesting to see what the tests show on Monday (or later if they end up having to send a sample out).
