Found dog (please help find its owners)

Hello! I found this sweet boy near Courtney-Huntsville Rd/Dinkins Bottom in Yadkinville Sunday night around 5pm. He was wandering in the road and it took me about 40 minutes to finally get in my car. He has a collar, but no leash. I know this is not technically Winston but it’s close and someone suggested in another subreddit for Nc I post here. I’m desperate. Me and my mom cannot keep this dog. My mom was supposed to take the dog to check today for a microchip but cannot (he’s really big and she can’t handle him) and I am working so I will be taking him tomorrow at 7. But in the event he is not microchipped and/or we cannot find its owners I am trying to put this out as much as I can. I HOPE he is just lost and someone did not dump him, and am trying to reunite him. I have contacted the animal shelter’s pages, sherrif’s office, have posts of Facebook as well as TikTok and pawboost / Nextdoor.
