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

This looks like a skin mass or tumor, but it is difficult to know exactly what it might be without being able to examine it in person. I would recommend having your vet take a look. They might recommend taking a sample using a small needle, or they might recommend surgery to remove the growth, especially since it is bleeding. In your picture the blood looks like it is near Snoopy's prepuce - if Snoopy is bleeding from his penis or prepuce I would recommend seeing a veterinarian on an emergency basis.

Poor guy. This does not appear to be just a lipoma (fatty tumor). I would highly recommend having Allie seen by your vet to get this tumor surgically removed and sent off for lab analysis to determine if this is a cancerous mass or a benign one. Hopefully it is benign and nothing to be worried about. The vet will likely place Allie on some antibiotics and pet friendly anti-inflammatory medication first to get the skin to calm down before surgical removal is done. But surgery is the best and often-times only option when a mass has gotten this large and has ulcerated. Until you can get her in, its best to clean this mass with Betadine diluted 50:50 with warm water to keep it from getting infected. Then rinsing with sterile saline from your local pharmacy. I hope that Allie's mass resolves soon! Best wishes and take care.

Yes, I would be worried because it's not normal for dogs to have bleeding lumps. It could be a cyst, but in a senior dog, there is always a concern that it's a malignant tumor. I would apply gentle pressure to the lump to try to stop the bleeding, and then have Raya seen by the vet in the morning. The vet can diagnose what is causing the lump, and can discuss treatment options with you. Keep her from licking at it overnight, and you may have to put an Ecollar on her to stop her from doing it. You can get one at a pet store, or can make one yourself: http://dogsaholic.com/care/homemade-dog-cone.html

In a dog Rugz's age, yes there is a chance this could be cancerous. 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.

an open and infected tumor should be removed. If it happens to be a lipoma (fatty lump) then this should be curative. If it happens to be another type of tumor, then your vet should do an x-ray of the lungs to check whether there are metastases. I think you should get a second opinion from another veterinarian or a veterinary oncologist.

Thanks for using Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Gypsie has this going on. I'm concerned that a bleeding, hard lump could be a skin tumor in Gypsie. If she is an older dog a skin tumor is a little more likely. She could also have a pressure sore or infection causing this issue. If you post a picture of the knot it may be helpful so we can provide more advice. There's a good chance that Gypsie may need to see a veterinarian to address this issue but it's hard to say without a better description or a picture. Definitely consider an exam with your veterinarian as I'm concerned if this lump continues to bleed it may get infected or cause more issues. Please consider posting a detailed description or picture so that I can help provide you more advice. Thanks again and regards to you and Gypsie!

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!
