My dog has a bloody black lump in her ear. Is it an emergency?
The most common reason that we see black crusting like that is when there is a small wound or mass that is bleeding a little and the blood is black when it dries. If it is a mass and was very small before and larger now, then it may need to be surgically removed. Since it has been there for a while, it would not be considered an emergency and the emergency clinic would likely recommend you have your regular vet evaluate it. However, if it is actively bleeding and you can't get it to stop, then it is certainly worth a trip to the emergency clinic. So, unless it is actively bleeding or bothering Zoey, I would contact your vet next week to have them examine it and decide on a treatment plan. We see a number of benign masses in young dogs and some require surgery to remove while some will resolve on their own. Here is a link with more information on one of the benign masses that we can see in young dogs.
