It could be an infection, cyst, allergic reaction, or mass. Have your vet take a look at the bump tomdetermine the cause. Your vet can do a fine needle aspirate to diagnose and then determine the best way to treat it. He may need an antibiotic, antihistamine, corticosteroid to treat or it may need to be removed.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Bingo. Without actually seeing this in person and examining the area there is unfortunately not much you can do. This could be a bacterial problem commonly caused by a staph bacteria that lives on the surface of the skin referred to as bacterial dermatitis or staph pyoderma. Other things this could be- a reaction to an insect, spider, flea, tick bite, a problems with a skin mite, a fungal infection, an epidermal cyst, or other. I would advise seeing your veterinarian so they can examine it more closely and then give you a good treatment plan to try to get this cleared up quickly. It may be hard to get the hair growth back in that time and it's possible this could get worse or suffer more hair loss. Your vet can get a thorough history and do a thorough exam of the lesion. They can then advise diagnostics if needed such as a skin scrape, woods lamp exam, fungal culture, etc. Once that is done, a sound treatment plan can be discussed and implemented. Otherwise you are only guessing at what this is. Good luck with Bingo.

Are you able to attach a picture? If you attempted that, it did not upload for us to see. :( That would be helpful. Based on your description, it may be a focal area of bacterial infection in the skin called pyoderma, it could be an inflamed hair follicle, or it could be some other type of mass. If you resubmit with a picture, can you let us know if its bothering him? Is he scratching or licking at it, etc, and how long has it been there? Thank you for asking Petco Pet Education Center, formerly Petcoach!
