My male dog has a red ring on his nipple. Is it ringworm or bite?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be due to ringworm though it is hard to know without an evaluation. This could also be just a focal skin bacterial infection, among other possibilities. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Ringworm can be transmitted to humans so just in case this is what is going with him, wear gloves when handling this lesion. Good luck and best wishes!

Hello there. Thank you for using PetCoach and thank you for including photos. My best guess is that this is ringworm. It does not look like a bite. I suggest you get Molekin' to your vet for an exam and to get a proper diagnosis for two reasons. Number one, ringworm is contagious to people and number two, an adult dog that gets ringworm usually has an underlying problem with their immune system. An adult dog should not get it. This is much more common in puppies. Remember, it is impossible for me to diagnose over the internet with just a photo. I am just giving my best guess. Many skin diseases look similar to the naked eye so that is why testing is important. Here is a link to an article about ringworm: ( https://www.petcoach.co/article/ringworm-in-dogs/ ) If you wanted to try something at home first you can buy over the counter athletes foot cream which is an antifungal and apply that twice daily. It may take 2+ months for it to clear completely up but you should start noticing a difference in a .couple weeks. If you don't have any improvement in 2 weeks or it worsens then you definitely need to get him to the vet. Wash your hands thoroughly after touching this spot just in case it is ringworm, you don't want to get it! ( https://www.walmart.com/ip/Lamisil-Cream-0-42-Oz/10294288 ) Hope this helps. Best wishes.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Duke. This could be ringworm or a sign of lyme disease, but yes it could also be a black fly bite. Black fly bites do not need any treatment. I honestly cannot make a diagnosis from a picture (and neither can a vet student), so I would have him seen by a vet. The vet can diagnose what is causing it and what treatment, if any, is needed. I hope this helps!

These red rings are often a sign of a skin infection. This could be due to a bacteria, or fungus. It's best to have this diagnosed by a veterinarian, because there is a chance that this is ringworm. We worry about ringworm, because it can spread to different parts of the body and can spread to people. Also, the more involved the infection, the longer it will take to clear. For now, I recommend washing your hands anytime you touch the area. For more information about ringworm and how to prevent spread, please click on the links below: https://www.petcoach.co/article/ringworm-in-dogs/ https://www.cdc.gov/healthypets/diseases/ringworm.html I hope that helps and Sixx gets better soon.

Thanks for using Petco Pet Education Center, formerly Petcoach! At least in these pictures, it does not look severe and I think this could have been from some form of mild trauma. I think it would be ok to monitor him at this point. If this has not gotten better in the next week or so, it may best to have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It looks more like a hot spot or a bruise. It doesn't really look like a ringworm but it is hard to be sure without examining Penny in person. Please, take all the precautions you would if it was ringworm (use gloves or wash your hand after touching the area) and take Penny to your local vets tomorrow.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Penelope has had treatment for mites and the other lesions resolved but not this one, this could be a separate problem such as ringworm, different mite or a benign tumor. I would recommend having the veterinarian look at this to help determine what the cause could be. Different medication would be needed for ringworm and if it is a tumor, it is likely what we call a histiocytoma, which is common in young dogs and resolves on its own. 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.
