Tell them not to bother with any dog. It's just not fair to the dog.
Because it doesn't matter about the breed all dogs need love and shelter not to be left outside so they can greet visitors and stuff like that.

Border Collies are fine farm dogs but not for just sitting around outside the only time I would tell them to get a border was if they had sheep or livestock and they were prepared to put the time and effort in to training it. I know for a fact that Borders need love they crave it, and they will do almost anything to get that word of praise or the belly scratch, so leaving one outside would proably destroy it just like it would any other dog.
