Hi everyone. This morning around 6:00am I let my dog outside to the backyard. And I fell backsleep in the couch. My yard door must of been open and the dog got out. We looked for the dog all over the neighborhood  for like 5 hours. Called the police department and no found dog had been reported. Just know I went to my front door and my doggy was sitting in the front porch 😍. I have the smartes dog ever I can't believe he found his way back home. He is an Australian Shepherd.
