Best dog I ever had, walked down the alley and adopted us. I was watching her out the window, and she stopped and looked in every back yard. We had horses, when she stopped at ours they walked over to the fence and checked her out, then she crawled under the fence, and the three of them walked over to the water trough and got a drink.
A few minutes later she walked over to the back door and laid down, stayed with us for 15 years, Vet figured she was close to 20 when we had to put her down.
Second best dog I had is the one I have now. Got him from the pound and that dude wont let me out of his sight when I get home.
