Pet's info: Dog | German Shepherd | Female | unspayed | 10 months and 4 days old | 45 lbs

What is this lump on my dogs ear. At first I thought it was a scab but after returning from vacation it is now grown to a point where I’m worried. It also no longer looks like a scab at all. What could this be and how do I treat it?

I suspect this is a histiocytoma, in which case, it should resolve on it's own within a few months. Don't put anything on it, just leave it alone. If it does not go away in a couple months then have your vet check it. ( https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952066 )

    Histiocytomas often resolve on their own but it can take a few months and they can be irritating, so if the dog is truly bothered by it then we will sometimes go ahead and surgically remove them. You may consider an e-collar to keep your dog from scratching/bumping it in the hopes that it bleeds less. Topical DMSO which is a liquid is sometimes used to decrease irritation. More information can be found at http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1676, but if it is really bothering your dog, removal may be the easiest solution!

Our dog Sadie has a growth or something on her ear it started about 1 month ago and it keeps getting bigger and bigger it's in her right tip part of her eat it's black in color she acts fine eating and drinking like normal but our other 2 dogs try a
That could be a histiocytoma which is a benign tumor that often will regress on it's own but it is difficult to be sure just by looking at some photos. Some other possibilities: an injury, an infection, a cyst, an autoimmune disorder. It is good you are taking her to the vet for an exam. They can tell you more after looking her over.

My dog has this warty looking thing on the edge of her ear. Is there anything I can do to treat this at home?
This appears from the photo to be a skin growth called a sebaceous adenoma and is likely benign. It is always best to have your vet examine your dog to make sure that this is confirmed. There is no way to make this go away without surgical removal by your veterinarian. These little masses can sometimes be a nuisance as they can bleed and become infected but otherwise are not typically harmful.

A lump has appeared in my 18month Rottweilers ear, she’s currently having ear drops twice a day(recommended from our vet to treat the lump), but it doesn’t seem to be helping at all? Two photos for comparison of ears, the yellow in the one with the l
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.

My puppy has had this on his ear for a few weeks now I clean with peroxide and put antibiotic ointment on but he keeps scratching and It won't heal does it need to be drained
Thanks for using Boop by Petco! It looks like a benign growth called a histiocytoma. These usually go away on their own after 3-4 months. I would recommend having a vet look at it and confirm. If it is, leave the swelling alone. It doesn’t need to be cleaned or have medication applied to heal it. Good luck and kisses to Boy Boy!

My dog has a lump on its ear I don’t know what it is
If you just noticed this, then it could be a bug bite. THere is a center scab there to suggest so. However, if it does not resolve on its own within 1-2 weeks, then it is considered to be a mass and should be tested by your vet or surgically removed and sent off for analysis to determine what kind of mass this is. I hope that this is nothing to worry about and resolves on its own. Best wishes and take care!

Should i be worried about the growth on my dogs ear photo attached?
I would definitely get it check and see about removal to be safe. There is a good change it is a histiocytoma which are not cancerous and sometimes can go away by themselves. however mast cell tumors can be aggressive and have the same appearance. you vet can take an aspirate to see if surgery is needed or if you can wait it out to see if it goes away on its own.

What is on my dogs ear? He had a lump like this a week ago and it went away in 24 hours and a new one just appeared.
It looks like it could be a tick but I really cannot tell with 100% certainty just by looking at the photo. I suggest you take him to your vet for them to check. If it's not a tick then they can tell you what it is - could be a tumor or a cyst as well.

My dog has a bump on his ear and I need help determining if it’s something that will go away or needs an attention of our vet.
That does look to be a mass. A mass is a collection of cells and can be benign (inflammation, cyst, some tumors) or a malignant tumor. Given the age of your dog this may be a histiocytoma, but as many skin tumors can look alike the best plan to confirm this is for your vet to perform a needle aspirate for cytology. That way you will know for sure if this can be monitored or if it needs any therapy. I hope this helps and thank you for using Boop by Petco!

What is this lump on ng dogs ear, just appeared, didn't have it 3 weeks ago
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.

Fatty lump appeared about two weeks ago. She doesn't yelp or act like she's in pain when we touch it or near it. It's located on her ear.
It does not appear to be a fatty tumor as they are typically under the skin. It is s growth though and unlikely to go away without surgery. It may be an adenoma or histiocytoma as these are common skin growths that are not cancerous and generally do not get much larger then what you have now a mast cell tumor is cancer and does have a similar appearance. I would have your vet check the cells to see what it is and see if surgery is needed for the best possible outcome
