My dog's nose has a growing bumpy discoloration. What is it?

Hello. While it is impossible to make any kind of actual diagnosis, a lesion like this most likely has an underlying bacterial cause. We often see isolated & well circumscribed lesions on the top of the nose or muzzle just from the fact dogs stick their noses in dirt or other nasty things all day long. Putting anything on this is not recommended because he will lick it off. You can pick up a skin antiseptic like Hibiclens from any pharmacy & just dab this on a couple of times a day. Once your vet has a chance to look, he may put Luna on oral antibiotics, or take a small sample to look at under the microscope. Other than this, there is no need to worry too much about the lesion. Take care, all the best to Luna & thanks for contacting Petco Pet Education Center, formerly Petcoach.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It could be due to acne development or other local allergic or inflammatory reaction. As long as this area is not painful and is not bothering your dog, you can monitor her at home for the weekend. However, if the area is sore or is bothering your dog, you should take her to your local vets tomorrow.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! A lot of skin bumps and lumps can look the same. She could have hit her nose on something and the bump is related to trauma and will go away, it could be a benign growth (like a histiocytoma), it could be part of a skin infection or immune reaction, hives or a cancerous growth. If the bump doesn't resolve in a few days I recommend having your Vet look at it. The sores around her mouth can also be due to infection or an immune condition and may or may not be related to the new bump on her nose. I hope this helps and I wish Luna a speedy recovery!

Ouch! That is a concerning sign, especially since the bump is a different color from the regular skin, and is growing in size. Since it's hard to tell what a bump is without an exam and sample (biopsy, fine needle aspirate), it's best to bring Coco into your vet to have it looked at. They can take the sample, check what kind of growth it is, and safely remove it if needed. In the meantime, keeping an eye on how fast it's growing/size, and keeping Coco from pawing at it or rubbing it can help keep it from getting infected or more irritated.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is probably from him rubbing his nose against a cage or something like that. I would suggest checking on that possibility. Otherwise, if that is not possible and this continues have him evaluated by a veterinarian for further assessment and treatment to check on a possible infection. Best of luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! Dogs can have changes in the pigmentation of their nose. This is rarely due to any significant medical reason. I do not think that you need to worry about this thankfully. Good luck and have a wonderful day and new year!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Princess. This discoloration and redness could be due to an injury, allergies, or infection. Without seeing her in person, I can't say what is going on. I'd have her seen by a vet in the morning. Best of luck.
