Josaphine, put aside , for the moment ,what we've said.
Just remember that choosing a puppy should be like being an actor. (If you are not nervous before going on you'll never be any good at it !)Right, well you've passed that test !
Above everything else, ask yourself the single key, most important question of all, which is:
" Do I think that this dog, a border collie, will be cleverer than I am?"
If the answer is "Yes" that's good. The dog will think that way too.(It's best that you are of the same mind. It makes training the dog much easier )
Frankly,to me you sound perfect for a border collie.(I'm with Lankeela too, in her opinion ) If you still have any thoughts, think of having a bitch rather than a dog. The bitch is likely to prove more tractable, and less boisterous and independent than a dog, more of a home body.That's broadly true of all breeds, not just this one. (If anything, there appears to be a predominance of bitches winning sheepdog trials.If that's so, the reason might be just that, that a bitch is a little easier and more reliable and settled in training up.)
Most breeds stick with you and love you when you feed their bodies. Border collies stick with you and love you when you feed their minds. They need clear rules to start with. After that their greatest joy is in showing what they can do, the harder the better,to prove how clever they are in interpreting and doing what the (to them), idiot but lovable human wants (and is so easily impressed or pleased by !) Seriously, you'll never ever see another look in a dog like the look on a border collies' face, as it sits looking up at its master saying " Is that all right? What next?" That's a reward in itself, for both human and dog.
