In most cases, the bleeding will stop on its own. However, this doesn’t mean that you should just wait for it to happen. As we’ve mentioned, there could be a more serious underlying condition causing the bleeding. The best thing to do is to take your dog to see a vet so that they can properly diagnose the problem and give your dog the treatment that it needs. One of the biggest risks brought by a bleeding tongue is severe blood loss which, if left untreated, could be fatal for your dog.
