So this past Saturday I had been playing indoors with a laser pointer light (Kiki was chasing it like mad around the house). Shortly after that, we noticed this lump on her shoulder. I took her to the vet Monday morning. The vet said it was a blood blister due to some sort of trauma - so the only thing I can think of is she ran into a piece of furniture. I'm with her all the time since I work from home and so I keep a close eye on her. Really not sure how this happened. Anyway, she drained a syringe full of blood out (which made no difference in the size of it) and said it should go away on it's own in about a week. Well it's been four days since we noticed it and no difference in size. Needless to say, I'm kind of skeptical of it going away anytime soon on it's own. Has anyone ever seen this or experienced it with your own dog?
