Sienna has been my best friend for about two years. We got her when she was eight weeks old. She is a beautiful and wonderful border collie. Like all border collies, she is extremely smart and knows over 15 commands. She loves her worn down Frisbee that she has had since she was a puppy. She still loves playing with it even though it doesn't fly that well. She loves to sit on the couch with anybody. Whenever I am sitting there doing work, she will hop up and lay down on top of or beside me. She is the sweetest girl, and I can't imagine my life without her!
