Rehoming 5 year old dog to good home

It's incredibly hard to have to do, but unfortunately I can't take my dog, Corndog, with me to my new home. He's a 5 year old mix and not fixed. About 40-50lbs. Grew up with an older dog (who kinda kicked his butt) and is incredibly friendly. He loves a walk but is just as happy with taking naps on the couch. Never had a problem with humping or spraying so we never got him fixed. I don't want to bring him to a shelter, I just want to find him a good home. Need to be rehomed by Aug 20th.
