Hello I was wondering if the red spot of my dog's ear is caused by something bad. It had happen yesterday in the afternoon but I thought it was something that had bit him or something else that may be causing him to have a little liquid bump on his ear. He shakes his ears not often like maybe 2 times a day. Your answers will help a lot thank you!

Charlie likely has an aural hematoma. This is where essentially blood fills a pocket under the skin. This is likely to grow in size and could become infected and causing pain. Sometimes we have to do surgery to drain this other times we can treat it with an injection. This can cause scarring of his ear. I recommend Charlie get examined by his veterinarian today to prevent complications. He may also have an your infection that needs to be treated to prevent him from continuing to shake his head.
