I have just come back from my vet because although he has A LOT, two on the head of my Basset have started growing and I thought it was high time to get this sorted out, hopefully once and for all. I've had the occasional hound with these, for no apparent reason - even siblings where one was covered with them (fast as we'd get some removed, others would appear until in the end, we only had them taken off if they grow too big, and in a difficult place), and her brother never had one.
My vet did a fine needle aspirate collection on three and thankfully they were 'just cysts' - he checked under microscopic exam. He is on a short course of antibiotics, but I'd love to know if anybody knows WHY these happen with some dogs, and not with others. My vet said, as I know, Bassets are prone to these but again, why?
