My DH and I take in rescue dogs. It is expensive but quite rewarding. This morning we received a video entitled "Smart dog". If any of you are interested in watching this, it was so wonderful, both my DH and I cried during the whole thing. Google Skidboot and watch the video of this dog. Or, if you want, send me your e-mail and I will forward it to you. It was so great to watch. Warmed our hearts.
