My dog has a bleeding ear bump that's growing. What could it be?

That does look to be a mass. A mass is a collection of cells and can be benign (inflammation, cyst, some tumors) or a malignant tumor. Given the age of your dog this may be a histiocytoma, but as many skin tumors can look alike the best plan to confirm this is for your vet to perform a needle aspirate for cytology. That way you will know for sure if this can be monitored or if it needs any therapy. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Ryder. This lump could be a cyst or a benign growth. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make him an appointment. I hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I do not think the mass has anything to do with being bitten in the area. It looks like a sebaceous adenoma form your picture (benign). It is very small and I recommend, if Lilly is a calm dog, removing it locally with lidoacine and a punch biopsy. It looks smaller than 8mm which makes it easy to take off with out anesthesia. If you decide not to take it off, I think that is fine. Dogs that form sebaceous adenomas tend to form more throughout their lives. Sometimes the dogs will lick or irritate them prompting owners to want to remove them. I hope this helps and I wish you and Lilly the best!

Thanks for using Petco Pet Education Center, formerly Petcoach! I’m sorry to hear Bella has a bump on her ear. I do recommend all new growths new evaluated by your regular veterinarian to determine if they are malignant (cancer) or not. I would keep your appointment, but if you are very concerned you could call and see if they have any earlier availabilities. Good luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! I think you should have this checked. The fact that it was previously known to be benign, does not mean that now it cannot be malignant. If it has gotten bigger, it would be great to sample it again. I recommend you have Lily evaluated by your veterinarian for a test called fine needle aspirate which is an easy, quick and pain-free procedure which in the majority of cases will help reach a diagnosis to identify what the best course of action is based on the findings. In some cases, a biopsy is needed for a diagnosis. If it truly is benign then removal is not necessarily recommended. However, if it is malignant and it has not spread to other locations, then surgical removal is recommended. Good luck! Keeping my fingers crossed that it is something benign.

This looks like a mass, which is a collection of cells. A mass can be benign (inflammation, cyst, etc) or malignant (skin tumor). The only way to know what this mass is would be by having your vet sample it. Typically we start with a needle aspiration for cytology. If concerning cells are noted removal with biopsy may be recommended. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

Hello. Because of this lesions' change in size & color, I would recommend just having it removed. It looks like a melanoma, but would need histopathology to definitively diagnose it. It is small so removal should be pretty easy. This would be a good time to have your veterinarian take a good look deep into Moka's ears. You may not see any infection, but there could be inflammation or even a foreign body like a grass awn down near the ear drum. Thanks for using Petco Pet Education Center, formerly Petcoach.
