My dog has an open sore on his lips. What can I do until the vet?

Pet's info: Dog | Black Mouth Cur | Male | neutered | 3 years and 4 months old | 50 lbs

My dog has an open sore around his lips. He started getting this cold in his lips a couple of weeks ago, I thought it might just be normal, never seen it before but it didn’t seem to be an issue and thought to keep an eye on it. Now he has this sore and I’m not sure what it can be. I have set a vet appointment, but they can’t get me in for another week.

It could be skin fold dermatitis, either bacterial or fungal. Until he gets to see the vet, you can try wiping it with a little hydrogen peroxide every day. You can also apply a little Neosporin, but he will probably lick it right off again.
