Hello. Today we noticed something weird on our Outdoor Dog. He has this round weird looking spot on his front leg. We took him inside and paid close attention to him for a while and it didn't seem to bother him at all. He didn't try to lick it, bite it or scratch it at all. He is usually underneath under trailer house to stay cool during the day. And we don't know what's under there. Could it be a bite? We clean it as much as we could but it doesn't seem like it's puss. It's like a white crust.

Hello there. Thank you for using PetCoach and thank you for including photos. My best guess is that this is ringworm. It does not look like a bite. I suggest you get Molekin' to your vet for an exam and to get a proper diagnosis for two reasons. Number one, ringworm is contagious to people and number two, an adult dog that gets ringworm usually has an underlying problem with their immune system. An adult dog should not get it. This is much more common in puppies. Remember, it is impossible for me to diagnose over the internet with just a photo. I am just giving my best guess. Many skin diseases look similar to the naked eye so that is why testing is important. Here is a link to an article about ringworm: ( https://www.petcoach.co/article/ringworm-in-dogs/ ) If you wanted to try something at home first you can buy over the counter athletes foot cream which is an antifungal and apply that twice daily. It may take 2+ months for it to clear completely up but you should start noticing a difference in a .couple weeks. If you don't have any improvement in 2 weeks or it worsens then you definitely need to get him to the vet. Wash your hands thoroughly after touching this spot just in case it is ringworm, you don't want to get it! ( https://www.walmart.com/ip/Lamisil-Cream-0-42-Oz/10294288 ) Hope this helps. Best wishes.
