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.

Hi and thank you for visiting Petco Pet Education Center, formerly Petcoach!
This large black lesion appears to be a skin mass. Skin masses that look like this can be either cancerous or benign (non-cancerous). The best way to go about finding out which it is, is to get the mass tested through your vet with a procedure called a fine needle aspirate. This is where the vet will take a small needle and draw off cells that are inside the mass and then put these cells on a slide to be read by a histopathologist who specialized in identifying cells.
I do hope that this is a non-cancerous mass after it has been tested. If it is then surgical removal will be the likely recommended course of treatment. Best of luck to you and Merlin moving forward on this. Take care.

Hi, and thanks for your question.
This lump/bump/growth should be ideally examined by your local vet to have a diagnosis established.
Your vet may want to perform an FNA (fine needle aspiration) or a biopsy to sample the bump and determine its underlying nature.
Differentials would include skin cysts, benign or more malignant type of tumors.

It is hard to say for sure without looking at it or getting samples from this lump. However, in an older dog I would suspect this may be a mass. In order to identify any mass on a pet, it is often required to get samples taken from it and having them sent off to the lab for analysis. This will tell us if this is a mass to be concerned about (cancerous) or not (benign). Therefore, I would recommend scheduling an appt with your pets veterinarian to have this mass examined, especially if it has been there for more than a few weeks, and/or is getting bigger. I hope everything turns out well for your pet BoJo. Best wishes.

My dog has a new lump on her ear. When should I see a vet?

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.

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

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. 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!

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

I would recommend having Lily evaluated by the vet if this mass is getting bigger. any abnormal growth that is changing in size and shape should be assessed to make sure that it is not malignant. A needle aspirate may give your vet enough clues to determine what this is, or they may recommend surgical biopsy or removal. Thank you for using Petco Pet Education Center, formerly Petcoach.

My dog has a lump on his ear flap. What could it be and is it serious?

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.

What to do if my dog has an ear lump and I can't afford a vet?

Any growth needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take her to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis. If money is an issue please contact a dog charity in your area of living, they can help with costs of treatment in many cases. Many vets also have payment plans, and there is also a credit company that will land you money toward vet bills ( https://www.carecredit.com/vetmed/) .

My dog has a growing red bump in her ear and shakes her head often.

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.
