My dog has red, irritated lips. Could it be an allergy or infection?

Hello so today after coming from school I realize that my dog had some weird tone/redness on his lips and I was wondering if it would be like an allergic reaction or some sort of infection. My mother said she gave him a normal Bath and brush his teeth. She thinks it has to do with her brushing a little too hard. The toothpaste is peanut flavored just in case if you need to know . This is the first time That this has occurred and we’ve been using that same toothpaste for a while and he’s good

Poor guy. Yes this does seem to be a localized reaction and it could be to just about anything that has been newly introduced or even something Mork got into that he is having an allergic reaction to. I wouldn’t suspect this is caused by brushing his teeth too hard because this is his lip area that looks irritated. It’s best to visit your vet for some medication to help combat this reaction, especially if this area is bothering him and not improving on its own within a few days. I hope that Morks skin clears up soon! Best wishes and take care.
