Right. If you're not 100% sure you are able to handle a border collie or not, then you should probably reconsider. I haven't owned Cali for that long, but she's nearing 3 months now (!) and already is a little whirlwind of energy!! I think the only reason she sleeps is because she chases me around the house for like... oh, 20 minutes NONSTOP.

They're incredibly smart dogs. Border collies are wonderful dogs and they're very loyal to their families, but you just need to make sure, and I mean completely sure, that you will be able to provide him/her with work, or plenty of things to do.
