Outside Dog

Joey has been doing this thing lately where he goes outside, but won't come back inside. Whenever someone goes outside and calls for him or even gets near him, he just looks at them and runs away. He will stay out there literally for hours before he comes back in. What gets really annoying is when we have to go somewhere but he won't come back inside. Sometimes I can get him in by tricking him into the garage by honking the horn of the car, shutting the garage door while he's barking at the horn, and then trapping him in the corner and grabbing his collar and yanking him inside. He has caught on to all my other tricks... like using treats, trying to get him into the car for a ride (which he usually loves) and pretending like I want to pet him. He doesn't fall for anything anymore and it is getting next to impossible to get him in... except occasionally the garage thing and when Kevin calls for him. Sometimes we end up just leaving him outside when we leave. I hate doing that because I worry he's going to run away. I swear I need to just build him a dog house and he can live outside all the time!
