Why is my Yorkie Poo growling when I touch the pink lump on her back?

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. 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!

Any growth needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Matilda 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.

Hi Dhyanna! At such a young age, it's not likely Muffin has a malignant tumor; even if it was one, you would have seen symptoms of malignancy by now. It could be a benign tumor that is slowly growing. The only way to know for sure is to have Muffin seen by a vet for this. The vet can diagnose what is causing this lump and how best to treat it. I would take her into the vet in the next couple of days.

Poor guy. This looks like a mass unfortunately. I would recommend having your vet test this mass to see if it is something to be concerned about or not. We need to get cells from this area and then send them to the lab to know for sure. But it is highly recommended to test due to the bright red color of this mass. I hope that this is just a benign histiocytoma which usually resolves on its own within a few months and nothing to be concerned about. Best of luck moving forward with your pet Charlie. Take care.

At Gracie's age, there is always a chance any lump could be cancerous. I'd take her back into the vet for it. 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.

Thank you for your question, and including a picture-this is very helpful. This little lump is likely something benign like a skin tag or similar, but I always recommend that if an owner notices changes in color, size or shape of a lump, especially if it is growing quickly, that it be evaluated by your veterinarian. If you are very concerned it would not be wrong to request that the lump be removed, then it can be submitted for review by a pathologist to let you know exactly what it is. You could always arrange to have Mieya's teeth cleaned at the same time, small breed dogs are prone to dental disease and this is a good age to start preventative dental care!

Unfortunately any skin mass can be cancerous but the good news is that most are benign. The only way to know for sure is the have a small sample of the mass collected and examined under the microscope. I recommend for Pepper to see his veterinarian. Sometimes the doctor can tell by palpation but other times they need to see the cells. Anytime you have a dark colored mass, melanoma is on the concern list. I hope this is helpful and please feel free to post any additional questions.
