Hi,
I think ALL the dogs on your list are fairly demanding dogs to own.
If you do want a border collie, then do go to a breeder, rather than a farm bred pup. The chances are, a farm bred pup will be far too work orientated to make a relaxed family pet. Unless of course you want a pup to work!
I dont actually know ANY border collies/working sheepdogs that arent farm bred, al the ones i know are itching to work. Those that do are happy dogs, relaxed when not working and lots of fun. But those that dont work, they are bonkers, leaping off the ceilings and very demanding, pushy dogs, some of them are also fairly nippy, and 'herd' their family members around, nipping ankles to get their own way.
That is not to say that the border collie is a bad dog, not at all, but one from a working environment will have far more drive to work than one from a show/pet environment.
