My dog has a red bump with green pus on his nose. Is it ringworm?

From the picture it actually looks more like a deep skin infection to me. This could be bacterial or fungal, or even a hypersensitivity reaction (less likely). I would recommend that she be examined by your veterinarian soon. They may look at a sample under the microscope to help determine what therapies might be most helpful. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

This presentation could be due to a localized spot of skin infection (likely to be caused by bacteria or fungal infection). A check up, appropriate disinfection and possibly antibiotics/or antifungal medications (oral or topical ) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine solutions. Buster collar may be useful as well to avoid any scratching (if any). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

This does look like a skin infection, but we cannot say whether it is bacterial or fungal. Your veterinarian may be able to tell with a quick exam and looking at the area with a special light that can diagnose ringworm fungal infections. In either case, this will be best treated with an oral medication....either antibiotic or antifungal. It is usually unrewarding to try to treat a lesion in this location topically because the dog will usually lick any cream or ointment right off. I would recommend that Neyle see her vet for a diagnosis.

Thanks for using Petco Pet Education Center, formerly Petcoach! This lump you describe could potentially be something like an abscess for example. However, other things like a growth are possible. I recommend that you have Arlo evaluated by your veterinarian for further assessment and treatment. If an abscess was noted, further local therapy with drainage and antibiotics would be recommended. Good luck and best wishes!

This looks like a mild skin infection or irritation from an insect bite or injury. You can wash it with antibacterial soap, rinse it well and then apply a thin film of antibacterial ointment on it. As long as there are no other spots this should heal fine. The overlying skin may come off and then the pinker skin may be showing until the fur grows back in which could take a month or so. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Mr. Brown.

A couple of things come to mind as possibilities. This could be an acute hypersensitivity reaction to something - bug bite/sting, perhaps - or possibility a severe bacterial infection called furunculosis. There are also some immune-mediated/auto-immune diseases that attack the top of the nose. See your vet about this. An appropriate treatment plan might be to start antibiotics and if no improvement after 2 weeks consider a biopsy to obtain a definitive diagnosis.

It looks like this lump could simply be a benign tumor, but that's impossible to say without seeing the dog in person. 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. I'd give your dog's vet a call to set up an appointment for sometime this week. I hope this helps!
