My dog has a red sore on his nose. Is it serious? What to do?

Hi thanks for your question. It is hard to say exactly what the sore could be caused by without examining Max and taking a sample of the lesion first. This should be done at your local veterinarian's office to determine if it is something of concern or not and if it needs to be treated. I hope this helps and I wish you and Max the best!

Thank you for using Petco Pet Education Center, formerly Petcoach! While this may be caused by a bite from another dog, from my experience, this looks a little bit more like a wound from nudging something constantly with the nose. Perhaps nudging a door to a crate, or sticking his nose under a door repeatedly. I recommend keeping a close eye on the area, and maybe even getting Bear an E-collar or "cone" so that he does not cause further trauma to the area. I advise against applying antibiotic ointments such as Neosporin as Bear is likely to lick them off quickly. I hope this helps and that all is well with Bear!

The most common reason that we will see a small raw area on the inside of the nostril is due to irritation of some type. That can be something as simple as a scratch from a stick or toy that will take some time to heal. I typically do not recommend applying anything to the area because it can make dogs try to lick or rub the area more which can make it take longer to heal. If your vet has examined it and is not concerned, then I would just recommend monitoring it. I would expect that it will slowly resolve as long as Otis is not continuing to irritate it. If it does not resolve in a couple of weeks or appears to be enlarging, then I would certainly have your veterinarian examine it again. Good luck! I hope that was helpful and answered your question.

I would put some neosporin in it twice a day. If it is deep, I would have your vet look at it to ensure she doesn’t need any stitches. I would not give her any human pain meds as most are toxic to dogs. I hope this helps!

Poor baby. Definitely looks red and irritated. It may need oral antibiotics or possibly just some topical antibiotics. I would call and schedule an exam and get the correct medications. The cause could be infection, allergies, immune mediated conditions, and more. Needs to be looked at a little more closely.

Given that this sore on Trixy has grown, I would have her seen by the vet. The sore could be caused by a skin infection caused by bacteria or yeast, or it could be ringworm. The only way to know how to treat it is to have it diagnosed, and the vet is the person to make the correct diagnosis. Once a diagnosis has been made, the vet can prescribe treatment. I would take her into the vet in the next couple of days. I hope this helps, best of luck!

Poor pup. It looks like an abrasion from this photo, commonly seen when dogs rub their noses excessively. This can happen with digging or being crated. I would monitor it but it does not appear to need intervention at this time.
