Well, I was on my way to puppy kindy and Azlan was being the lovely little genlteman that he is, lieing quietly on the front seat, so I put my hand on his shoulder blades in a friendly gesture, whereupon I found a LARGE lump! I was shocked to say the least, I certainly had never noticed it before. It's on his left shoulder, and a little smaller than a golfball, only flatter as well. I was thinking this could be a reaction to his last vaccination, which he got on friday. If anyone has any ideas I would most appreciate it.
