My dog has a growth on his ear. Is it a wart? How to identify?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. Based on its appearance, this is most likely a benign sebaceous adenoma. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good one!

This looks like a wart or benign mass from the photo. Usually malignant tumors grow more quickly, and are not as well defined as this. The only way to know for sure though is a biopsy. If he continues to irritate the growth then certainly I would have it removed and biopsied. If you wish to monitor it I recommend taking a photo and measuring it at least monthly so you’ll know it it starts to grow or become more inflamed.

In the picture, it looks like a mass to me, so I would recommend going to Rey's vet to have it sampled (quick, easy, no sedation required) and the cells looked at under a microscope to see if it's something concerning. Young dogs can get a benign mass called a histiocytoma that goes away on it's own eventually, which would be my first guess. Your vet might say it's a wart when they see it in person, in which case no sampling is needed, but keeping Rey away from other dogs until it's been gone for 2 weeks is a good idea because the virus that causing warts is very contagious. So, you don't need to be highly concerned, but should have it looked at.

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!

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!
