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!

My puppy has a little bump on his ear. I notice it doesn't hurt him. He has had it for a couple of weeks now and it got a little bigger. Its has a very dry/hard skin on top.
Thanks for using Boop by Petco! This could be a benign or malignant growth. This could even be an infection though it is hard to know without an exam. 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!

I’ve suddenly noticed a lump on my dogs ear. There isn’t any anywhere else and I have no idea what it is. Any advice would be appreciated! Thanks

I just found a lump on the ear on the pinnacle flap of my Basset Hound called Bertie. He is 3yrs 10 months old. He's in good health otherwise. Has been a bit off form this week.
Hi and thanks for using Boop by Petco! 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.

Hey I was out playing with smokey and I noticed a pink/ red bump on his ear. At first I thought he had a tick but when I got closer it’s not and it’s soft and like peeling skin. It’s at the tip of his ear, what could this be?

My dog has this bump on his ear that has progressively gotten worse and we're wondering what it could be and how urgent we need to be with it. It started as a small pink bump then turned to an irritated red and now its 'shed' a crusty brown skin and

My dog has a growth on the flap of his ear and it looks like an ingrown hair I am concern and would like to know if I should take him to the vet. I know that you are at Petco today
Thanks for using Boop by Petco! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Reggie evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!
