Rottweilers are smart
When I came back from the grocery store my 10 week old Rottweiler was on the front porch of my house. I knew I had left him in the back yard and it kept me wondering how he got out and ended up in the front.
So I investigated the back yard. He had dug a hole under the gate and crawled under it. I didn't notice he had crawled under the gate because he had no dirt on him. It was a good thing that no one had stolen him!
When I saw him on the front porch he was hiding behind a tree and looking at me like I know I'm in trouble. I just looked at him and started laughing :0)
So if your dog is an in door dog, don't leave the dog outside because I learned the hard way. :)
