I leave breeding to the experts and to those who don't mind not being able to find homes for all of their puppies. Besides that, the number of Border Collies in rescue centres here in England is criminal.
People initially buy one because they see how good they are at agility on the television shows, but then they treat them it like any other dog, sometimes not walking it enough, or not stimulating it enough, not giving it enough company, or having screaming kids running around it. A standard dog under these circumstances is bad enough. A Border Collie under these circumstances is your worst nightmare, so it inevitably ends up in a shelter. In fact, we got ours, luckily as a twelve-week old puppy, through a local shelter. She was a pup from an accidental breeding of two working farm dogs.
A Pembroke Welsh Corgi was my first ever dog, when I was a wee child. Gorgeous wee dogs.
