More: My Border Collie Macy Lu is an amazing dog - great companion and family dog! Like most Border Collies she is very active and enjoys chasing tennis balls, catching the frisbee and going for walks and runs with me! Macy Lu is a very sweet girl and gives out lots of kisses to everyone including my grandkids! Macy Lu is also very vocal and is great about expressing her needs and wants! I have a rescue Lulu who is a great dog and smaller than Macy and if the doggie door is closed will come get me to let Lulu and her out! She also is a great chicken watcher!
