Why does my dog get a rash around his mouth and nose sometimes?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 10 years and 6 months old | 15 lbs

My dog I had been getting something that kind of looks like a rash around his mouth. It appears and then it disappears after awhile. Today I noticed that this time he has it in the front area of his mouth and around his nose also. I have no idea what he has or what might be causing it.

I am sorry to hear about your dog! If this is coming and going I would wonder if there is something he is occasionally getting into that he has an allergy to, such as a plant in your yard. Or perhaps he is getting a special treat/table scrap on the days he breaks out that he has an allergy to. I would recommend bringing him in during a flare up for his vet to examine him as we do worry when we have lesions develop along the edge of the nose about autoimmune disease, so he should be examined to ensure this isn't something that needs to be further investigated.
