My dog has large boil-like bumps on her back foot. What are they?

Hi. That looks like a mass on that foot. It could be benign, or malignant. It is hard to tell from this picture. It could even be something as simple as mole/wart like mass. The way to know would be to have him examined by your veterinarian and have the perform a cytology. A cytology is looking at the cells of these masses at the microscopic appearance of cells, studying them especially for the diagnosis of abnormalities and malignancies. Good luck.

Thank you for using Petco Pet Education Center, formerly Petcoach! It is definitely concerning that the lump has increased in size so quickly, as older dogs are typically more likely to develop cancers. The lump can also be an infection or cyst. I recommend having this seen by a vet as soon as possible - they can take a small sample from the growth to determine exactly what it is and recommend the appropriate treatment. I hope all is well!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern! From the pictures you have provided, this appears to be what we call a sebaceous adenoma. This is a benign skin mass that we typically start to see develop in middle aged to older dogs. They do not cause any harm but can become sore and open from time to time. If these masses become infected or are painful I then recommend having them removed, otherwise, monitoring them is absolutely fine to do. 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 is a well defined growth luckily. As it’s getting bigger and it is large enough to get scraped and start bleeding I recommend removing it soon. It looks benign but a biopsy will be needed to know for sure what type of growth it is. If it gets much bigger it will be difficult to remove since there isn’t much extra skin in that area to close up the incision. All growths that enlarge should be surgically removed to prevent problems. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Rocco.

Hello. This looks like a small cyst, nothing too worrisome. It may pop & if it does, just clean the area with a good skin antiseptic like Hibiclens ( available at all pharmacies ). A warm compress or soaking the foot in warm water for 10 minutes 2-3 times per day may bring things to a head sooner, but this does not appear to be at all dangerous.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. This looks like furunculosis which is a deep bacterial infection of the skin. It will not resolve without a long course of oral antibiotics. Now, that being said, this could be a primary issue or a secondary issue - I cannot tell you without examining her myself and doing some testing. You really need to take her to your vet for an exam as soon as you can. Hope this helps. Best wishes.

Oh no, poor Coby! He could have a foreign body in his paw causing the bump, bleeding, and his licking it raw. It sounds like you've done a good job of covering it tonight, and I would put an Ecollar on him to keep him from licking at it. I will put a link below on how to make an Ecollar at home. Then I would have Coby seen by a vet first thing in the morning. The vet can diagnose what is causing the bump and the best way to treat it. http://dogsaholic.com/care/homemade-dog-cone.html
