My dog has a bleeding boil or blister on his neck. What is it?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Gunnar evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Thanks for using Petco Pet Education Center, formerly Petcoach. It looks like it could be a sebaceous cyst that got infected and ruptured. These are benign but sometimes they do keep opening and become bothersome to the pet until you surgically remove them. That being said, in a dog of this age, I always recommend seeing your vet for a closer inspection and a needle aspirate if needed- just to make sure it’s something benign. For now, I recommend an E-collar for Hank so that he can lick/chew at it. Then clean the wound with some hydrogen peroxide. Best wishes to you and Hank!

Hi there and thank you for using pet coach to address your concern. Based on the pictures you have provided, this could be a cancerous tumor that has become infected. This should be examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. It is likely he needs to have surgery to help try and resolve this. 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.

This appears to be a large, infected mass. You will need to take Roscoe to the vet as soon as possible. Your vet will likely recommend surgery to remove the mass and antibiotics to help the infection clear up. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hi there and thanks for using Petco Pet Education Center, formerly Petcoach! I would recommend taking Bentley to have that looked at-while it is possible it is nothing more than you have described-there is also a possibility it could be a small tumor made of vascular tissue. Your doctor can do a needle aspirate or a biopsy while you are there. I'd have it looked at soon just to make sure it's nothing more serious-they can also help with the bleeding if there is no further concern

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/

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!
