Why is my senior dachshund's belly lump bleeding? Is it serious?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Dexter. I agree, that is concerning that this hard lump is now bleeding, and this lump could be something serious. It could be a hemangiosarcoma (malignant) or hermangioma (benign), which are tumors that develop from blood vessels and look like a blood blister. Given his age, there is a chance it could be another type of malignant tumor, like a mast cell tumor, but it could also be benign. Unfortunately without seeing him in person, I cannot say for certain. 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!

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!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for the pictures! Many skin masses can look the same. Red dermal masses, like this one, can be benign or malignant. Some possibilities are an inflamed sebaceous adenoma, hemangioma, histiocytoma or it could be a Mast Cell Tumor. Since it showed up quickly I would have Oscar seen by your Vet. They can decide if aspirating it (sticking it with a needle and sending the slides to the lab) or removing the mass and sending it for biopsy is best. I hope this helps and I wish you and Oscar the best!

Thanks for using Petco Pet Education Center, formerly Petcoach! Blood in the urine can be observed with things like urinary tract infections, urinary tract stones and even urinary tract tumors. The masses under the skin can be due to a benign or malignant growth. Both of these conditions can be linked or be completely separate issues. A urinalysis and urine culture can be performed to check the urine. Abdominal imaging may also be recommended. The lumps could be benign or malignant growths. 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 her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This could even be an abscess. 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 her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign.

Hi, thanks for using PetCoach! Poor Moco! Due to his age, the appearance and the location it looks like a histiocytoma. Which is a benign mass in young dogs. They tend to resolve on their own in a few months but sometimes if they ulcerate, grow rapidly, become infected or bleed we recommend removing them. Another possibility is a mast cell tumor. I would suggest having it looked at my your vet. Good luck! https://www.petcoach.co/article/histiocytoma-in-dogs/
