My husky had this blister like thing above his green line tattoo, and it popped. It started gushing blood. And it doesn’t really look like it in the pictures but it’s a pretty deep hole. I can’t see the end of it. I held a cloth over it until it stopped but I have no idea what it could be. It was clearly hurting him, he was whining when I touched around it. It’s also the size of quarter. (Not the hole, but the diameter of the entire thing including the swelling.)
What could this be and what should I do?
