Why is my dog's bleeding lump near his whiskers not healing?

Thanks for using Petco Pet Education Center, formerly Petcoach! This may be a benign or malignant growth. This could even be an infection. This cannot be completely assessed just by looking at pictures or reading a description and usually requires sampling such as fine needle aspiration to determine its origin. 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 night!

Thanks for using Petco Pet Education Center, formerly Petcoach! I recommend taking Sable to the vet to look at the growth closer and find out what it is. The vet can stick a needle in it and look at the cells under a microscope to determine if it’s cancerous or not. Because the tissue/skin is fragile it likely won’t stop bleeding and may need to be surgically removed. I would leave it alone until the vet looks at it so you don’t disrupt the blood clot that forms. Good luck and kisses to Sable!

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!

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/

This looks like a typica skin wart/skin tumor or cyst. Since it has been present for so long and has not grown at all, it is probably benign (non cancerous). It looks as if the area has been irritated somehow, probably by your dog scratching at it, and is now bleeding and may be infected. Or, if it is a cyst, the white material may just be cystic exudate. I would recommend cleaning the area with some dilute hydrogen peroxide then applying some antibiotic ointment to help prevent infection and to help it heal more quickly. Occasionally these need to be removed but only if they are a constant source of irritation or infection for the dog. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Piper! The only way we can 100% know for sure a mass isn't cancerous is by either aspirating the mass with a needle or biopsying it. When a mass changes I always recommend that the animal be seen by their Vet to have it checked. The fact the mass opened up dictates the need to have it looked at and a minimum of antibiotics started. Hopefully it is just a ruptured follicular cyst that is infected. But I think you should have the mass removed and biopsied. I am afraid it will not heal well and continually leak bloody fluid. I hope this helps and I wish Piper the best!

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!
