I was coming in the bags of grocery with my dog. Apparently a bottle of extra spicy salsa wasn't packaged properly and broke open while I was coming in, conveniently over my dog. He got a little on his head, though none in his eyes. And quite a lot all over his back and tail. This isn't just regular salsa from a jar - it's from a Mexican grocery store that specializes in extra hot homemade sauces.
I immediately threw him in the tub and washed it all off.
A couple hours later, though, he is constantly licking his anus (which he does often anyway) but his anus is bright red and appear inflamed. I'm guessing he managed to lick his body and then lick his anus and got some of it on.
Ideas on how I should handle this? I wiped his anus with a wet paper towel. Not sure if there's anything else I should do or if I should just wait it out.
