Chandelle is my first Border Collie and wow am I impressed. She is a very quick learner but we have had problems with her play biting us. She also tried to herd us. We have pretty much taken charge of these issues and gotten them under control but Yiiiii! How long do they stay this oral??? She has a kazillion chew toys and enjoys them all. I had to spray bitter apple on the chair rungs and Gene's house slippers, oh and the electric cords. We never leave her unsupervised. She has a crate for nights and an outdoor kennel for times when we need to get some work done and she should have the freedom to romp. Any suggestions, and related stories of puppyhood with your dogs will be appreciated.
