The dog didn't run!

My dog is an escapist. He loves to get out of the house and run around the neighborhood. It hasn't happened in a while, since we have kept a tight reign on him and finally taught the Kid that it is NOT okay to just open the door while the dog is running loose in the house.

This morning, however, I put his leash on him and sent him outside like I usually do. Something told me to look out the window and check on him. His entire choke collar was off, and he was standing there looking up for the dogs that live above us. Why didn't he run? I calmly opened the door and called him back in. Normally, he would say "haha screw you!" and take off. Today, he just excitedly came back in and sat down with me. I pulled his leash back in, put it back on, and sent him out again. The dog seemed never the wiser about what had just occurred. I have to wonder if he knew and just didn't care to run away, or did he not even notice. Either way, he is still outside sitting in his favorite spot enjoying nature going by and I am here not having to worry about whether or not he will eat someone else's pet.
