My senior dog's neck lump is bleeding. Is it dangerous or a lipoma?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Female | spayed | 10 lbs

My dog has what we think is a lipoma on top of her neck. She has had for many years and due to her age, it's too dangerous to remove. Today I came home and it was bleeding pretty bad, it did not burst, looked as if she had a small cut on it. Does this pose a danger and does this look like a lipoma to you or something else? She is 18 years old

Poor Gidget! Without being able to see it in person, it is difficult to say for sure. I would have your vet take a look at it since it is hairless. It is likely just a fatty tumor but I have seen a malignant type of skin tumor called a mast cell tumor look like that. Granted, we do have to keep in mind her age. You may decide just to keep her comfortable and make sure the area doesn't get infected and that isn't a wrong decision either. Your vet will be able to determine whether or not it is malignant and also make sure the part that is bleeding isn't going to get infection. A dog her age would have a hard time getting over an infection if left untreated. I hope this helps!

    Yes, Gidget should go see her veterinarian. I’m concerned that those red lesions are severe vasculitis or areas where the tumor is out growing it’s blood supply. The doctor may try something like steroids and topical care. Infection seems less likely but the doctor will check for that as well. Best of luck and I hope this is helpful. Please feel free to post any additional questions.
