If you have ever noticed a lump behind dogs ear, you might have wondered what it is and whether you should be worried.
Lumps behind dogs’ ears can have various causes, ranging from harmless to serious.
In this blog post, I will explain the most common types of lumps behind dogs’ ears, how to identify them, and what to do if you find one.
What Is A Lump Behind Dogs Ear?

Your dog may have a tumor in its ear and not show any signs until it grows too big or you see it.
Most ear tumors are harmless, and some don’t need treatment unless they bother or hurt your dog.
But many vets recommend removing ear tumors, no matter where they are or what they look like, to prevent infection, pain, and more growth.
Ear tumors come in different shapes, sizes, and colors. They can look like small bumps on stalks (polyps), big masses in the ear, or flat patches that stand out from the skin.
You can see that some dogs are more prone to ear tumors than others, especially those with long floppy ears like Beagles, Cocker Spaniels, and Golden Retrievers.
If your dog sometimes has frequent ear infections, the risk of ear tumors, especially cancerous tumors, can be higher.
Which Common Kinds Of Bump Behind Dogs Ear?
It would be best to consider different kinds of bumps on dogs to have the right treatment of choice when your dog is stuck in these health problems.
Two types of lumps can be commonly found on your dogs, including non-cancerous and scariest lumps. In particular:
Benign Lumps (Non-cancerous Lumps)
You love your dog and want to keep it healthy and happy. But what if you notice a small bump on dog ear? Should you panic? Not necessarily.
Many lumps on dogs are benign, meaning they are not cancerous and do not spread to other body parts.
Various factors, such as infections, injuries, cysts, warts, or fatty deposits, may cause them. Some of them may disappear on their own, while others may need complete vet removal.
You must check your dog regularly for any lumps and bumps and consult your vet if you find one.
Remember that early detection and treatment can greatly affect your dog’s well-being.
Malignant Tumors (Scariest Lumps)
Malignant tumors are the worst tumors you can find on your dog. They are cancerous and can spread to other parts of the body, causing serious damage and even death.
Malignant tumors can affect any organ or tissue in your dog, such as the skin, bones, lungs, liver, spleen, or lymph nodes.
They can cause symptoms such as weight loss, loss of appetite, lethargy, difficulty breathing, swelling, pain, or bleeding.
It would be best to notify your vet immediately of the abnormal growth from malignant tumors in your dogs. Your dog’s life may depend on it!

Dogs With Large, Floppy Ears (Cocker Spaniels, Golden Retrievers, Beagles,)
Some dog breeds, such as Cocker Spaniels, Beagles, and Golden Retrievers, are known for having large and floppy ears.
However, these ears can cause lumps on dogs for various reasons.
One is that they trap moisture and dirt inside the ear canal, which can lead to ear infections and ear tumors.
Another is that they are easily injured by biting, scratching, or shaking, which can cause ear hematomas and abscesses.
Therefore, you need veterinary attention to take care of them regularly.
History Of Multiple Ear Infections (Otitis Interna, Otitis Externa, Otitis Media)
Multiple ear infections can easily lead to lumps on your dogs’ ears because they can cause damage to the ear tissues or glands.
Infection can also cause your dog to suffer from inflammation, irritation, discharge, odor, or pain.
Don’t let your dog’s ears become a breeding ground for bacteria, yeast, parasites, or foreign objects.
Check your dog’s ears with common tests regularly and take them to the vet if you notice any signs of infection or lumps.
Long-Term Inflammation Of The Ear Canal
Long-term inflammation can also cause further swelling, discharge, and pain in the ear.
If you leave your dogs with these clinical signs for a long time, they can grow into malignant or benign lumps.
It means that you must have a veterinary exam immediately to restrict the impact of inflammation.
Repeated Infestations Of Ear Mites
If your dog is scratching and shaking their ears excessively, it may be due to ear mites. These tiny parasites live on the skin’s surface and feed on ear wax and debris.
However, their presence can damage the ear tissues and glands, potentially resulting in lumps or tumors.
You should take a physical exam to detect how many ear mites are in your ears and whether you should take all of them out of their ears’ dog.
Thickening Of The Ear Wax For Any Reason (Usually Unknown)
Your dog’s ear wax is a natural defense against dirt and infection. But too much of it can be a problem. It can harden and clog the ear canal, trapping moisture and germs.
This can lead to lumps or tumors in the ear that can damage hearing and balance. Don’t let your dog suffer from ear wax overload. Keep its ears clean and healthy.
