My dog has a lump inside her ear flap I can only feel. What is it?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Bertie. Lumps generally fall into a few broad categories including growths/tumors which can be benign (not cancer) or malignant (cancer), granulomas which are a collection of inflammatory cells, abscess/infection, among others. In young dogs, a common benign tumor called a histiocytoma can develop. These are raised growths, often pink and somewhat flat like a button. These growths oftentimes resolve on their own without treatment. I would advise that your veterinarian take a look at Bertie. They can get a detailed history and do a complete physical exam focusing on the area of the growth, They may advise diagnostics such as a fine needle aspirate or a biopsy of the growth to determine what it is. If they suspect a histiocytoma they may just advise monitoring the area but to also be on the lookout for any scratching of the ear/growth. Once a diagnosis is obtained or suspected, a sound treatment plan can be discussed. The ear is a tricky area for growths and their removal because of the lack of skin to close over the incision if they are removed. Thus, a growth in this area warrants a quick analysis by your vet. Good luck with Bertie.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Bear. This bump could be a benign or malignant 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!

If this just showed up, I would recommend having a veterinarian take a look at this. It may be a type of tumor that needs to be removed called a mast cell tumor. I would err on the side of caution and have the veterinarian look at this and perform some additional testing on it. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

This could just be a benign growth but without seeing Mac in person, I can't say for certain. Any suspicious lumps should be examined by the vet.

This is likely just a cyst or possibly a localized infection. Since it isn't changing and your dog doesn't seem to be too worried about it, I wouldn't be too concerned. I would just wait for your vet to call you. If you haven't heard from them in a few days, I would call them to double check on the results. I hope this helps!

This lump could represent a cyst like structure or a neoplasia (tumor) or a spot of infection. It is essential to have it checked by your local veterinarian as this could be sampled to determine its underlying nature. Your vet may want to perform an FNA (fine needle aspiration) or a biopsy to sample the bump. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!

Hello, that lump appears very similar to a histiocytoma. These tumors occur in young dogs primarily, are benign, and resolve on their own within several weeks. This should be confirmed by obtaining a sample from this tumor with a needle or by obtaining a biopsy. Have your veterinarian re-check Lola, especially if her lump is not resolving with medications and talk about sampling the lump. Hope this helps and best of luck.
