It's nice to have a buddy for them when no one is home. It took me a while to find the fight buddy for Chip though, I was super picky because I wanted to make sure I got the right one for him. My criteria was for his future buddy to be a boy, about the same age, size, temperment. Luckily, it all worked out with Harley. Now they are best buds, its like they enjoy having each other as a roomie.
