Small nodule on dog's armpit, what is this? General Dog Discussions
I have a 6 year old Black Staffordshire Bull Terrier. He recently had a small pimple under his armpit. A somewhat greenish colour but still mostly fleshy and shaped like a tomato pip moving directly up and out. It stood up quite tall for just a normal spot. Underneath is a bit of red swelling. The pip shaped pimple came off and the swelling is going down a bit but it looks quite sore. There doesn't appear to be any puss yet but I'm just wondering what it is. I've looked all over the internet and I just can't find a match.
