My dog has a growing lump on his ear. What could it be and what to do?

This may be an abscess, a cyst or a tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.

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!

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.

Please know that without seeing Snoopy in person, there is no way for me to say for certain what is causing his lump. It could be a cyst, an abscess, a benign tumor, or a malignant tumor. 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 it's 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 with you. I would take him into the vet on Monday to have this lump examined and diagnosed so it can be treated as needed. Good luck, I hope this helps!

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.

Poor guy. This lump appears to be a huge mass and possible polyp. You will need to get this tested by your vet and seriously consider surgical removal of the mass. If left there this mass has a good chance of causing chronic ear infection, pain, and also can continue to grow. It is best to get this removed, so please consult with your veterinarian to devise a good plan for Little Bit in the near future. I hope that LIttle bit's ear mass gets resolved soon. Best of luck and take care.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. 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 day!
