My dog has a weird spot on his nose getting worse. Vet visit?

Ouch! Due to how inflamed that looks I would definitely schedule a vet visit ASAP. Sudden growths/irritations like that can be due to a number of things including bacterial infections, tumors, irritation from digging/rubbing at the spot too much, allergies, etc so it's good to see your vet. They'll likely want to take a sample of the area to determine what is going on and how best to treat it. In the meantime, it's a good idea to place an Elizabethan (cone) collar on Nova to keep her from rubbing at the spot, as well as keep the area clean and dry. If the area is rapidly growing in size, taking note of the size, color, shape changes, etc can help your vet better determine what is going on. If you are noticing any other symptoms (sneezing, fever, loss of appetite, etc) these are important to let your vet know as well.

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid rubbing/scratching if any. 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.

Ouch! Any new or suddenly growing growth like this should be checked out by your vet in person ASAP. Allergies, infections, skin irritation from rubbing it on things, and some growths and tumors can all cause spots like that on the nose, and can also cause rapid changes and discoloration like this. Until you can get to your vet, I would place an Elizabethan (cone) collar on Amber and keep the spot clean and dry to help reduce any further irritation. It is also a good idea to monitor the size and shape of it and how rapidly it is changing as this can help your vet figure out what may be going on. Your vet will likely take a full history as well as a potential sample of the spot to see what cells are present and provide treatment as needed.

If the spot has changed in size over time it wouldn't hurt to have your vet take another look at it, especially if the change was very rapid over the past few days or weeks. Your vet may recommend taking a sample of the spot for testing to help determine what it may be so it can be treated as needed. Growths like this can be caused by any number of things including rubbing the spot often on surfaces, cysts, blisters, allergies, etc, so having it examined if it is changing is best.

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.

I would definitely recommend having it sampled in the vet office. It's possible that it's just a wound, or it could be an infection, cancer, or even something like an immune mediated disease. You don't need to take him to an emergency clinic, but I'd recommend having him see early next week to try to get a better idea of what's going on. Good luck, I hope it's nothing.
