I'm thinking Nicki can remember.......

We took Snowy home when she was about 6 weeks old. Around a year later we brought her back to the people we got her from so they could watch her while we went on vacation. Right when we turned on to her block Snowy's tail started going, she started barking, and she knew which house it was before we did.

That was her first home. Her mom, dad, and sister all live there. Now we can get on the street before their block (or sometimes much farther back than that) and Snowy will know where we are.
