Border Collies need a lot of mental activities, as well as lots of exercise. If not they can become destructive. I would wait until you get the room for the dog. If you get a dog bred from working lines, you won't have to "train" it to herd, you just need to work with it's natural instinct, and teach it the cues for what you want. I have border collies, they have differnt levels of herding instinct. One is so driven, that she tends to get tunnel vision and needs to have commands shreamed at her to get her attention. She also will "grip"(bite) the sheep & goats. Is NEVER allowed out with the birds, will herd them to death, and will try to "move" them by gripping. One had so much "eye" she would get fixed on her pray, crouch, and stalk EVERYTHING! You could not ride a bike when she was out, she would try to stop the wheels by getting infornt of them and stare. She would also nip anyone who ran in the yard, kids, birds, other dogs. My last was shown in obediance & agility before working livestock. Very smart and easy to work with, but when I was PG and not able to work him everyday, I woke up to find holes in the drywall. He would chew on it out of fustration. So you might want to wait and reside if you can give a border collie what they really need. I love them, but I also enjoy arab horses, both need someone who can think outside the box, and be 3 steps ahead of them. Good luck!
