Oh, they are beautiful dogs. I didn't realize they were so smart as well. What was your dog's name? We have a shelter save that I believe is mostly border collie, and she's smart as a whip, but, oh, so, so, energetic. I can take her on a quick-paced hour-long walk, and it barely makes a dent in her energy level. She needs frequent running off the leash and she wears our black lab down. She will respond to a couple hand signals; I really should work with her more. I tell my family she could be a TV star, and they roar, as she's sort of mischievous as well (chews, chews, and irritates the cats).
