I'm been wanting to get a border collie and have been doing a lot of research lately. A huge topic that comes up is that they need a lot of exercise and attention. I am an active person and need to know how much time exactly is needed to take care of a border collie. How many hours a day do you need to spend with your border collie? (Walking, running, playing, training) How many hours a day can you leave your border collie unattended? How many hours a day do border collies sleep? and do they sleep multiple times a day?
