I have a border collie mix, but she is all border collie in her personality. She is very high energy, but calming down a bit as she has left puppyhood. When I take her to the dog park, she herds the other dogs. She also herds my two cats, which they don't really for. She is a bit clumsy but gentle. We have Jessie stay in a crate when we go to sleep and she loves it. She puts herself to bed when we go to bed. We also put her in the crate when we are at work because it stops her from having garbage parties in the house. We are certain not leave her in for too long. She was very easy to potty train, she was done at 3 months. (However, when we went on vacation, she decided to tell us he did not like that and pooped in the house.) She is very smart and will do any trick you teach her for a cookie. Extremely agile, she static jumps about 5 feet in the air and is great at playing catch. She loves people and kids and most dogs. Since she is a herding breed, I don't have to worry about her running away. She stays close and is a great hiking companion. I could go on forever, but I hope this gives you some idea.
