Gawd I love Border Collies! Thank you for saving sweet, gorgeous Angel from her life of hell. I'm sorry I missed your original thread. When I first adopted Logan, she also nipped when we ran or walked in the yard. I think it was her herding instinct and not meant maliciously. (actually she nips at the heels of our shoes especially when she wants to play, and the heel of all my sneakers are shredded. She'll grab the heel, especially on the steps, so you can't move-it's her favorite "game")

WOW! She and Muffin DO look like sisters! What a beautiful pair! With all the good lovin' and fun in your house, I'm sure Angel will adjust in no time. She must be so shocked that people can be so caring, she doesn't know what to do! I hope the previous "owner" gets his just "reward".
Happy Tail Waggin'!
