In reply to Dave C: Kelpies are great dogs, OK not as wiley as a collie, but a bit more physical, have to be given the opportunity to run, but that is the same with collies and most hounds.
The GF has one in Aus, it turned up on christmas day, just a stray walked upto them, and decided to stay, been with them 8 years now, great temperament.
I wouldnt get any dog, like a kelpie, hound, collie, unless I was prepared to work it properly, its cruel not to, they are bred to work 8 hours plus a day, you have to run them, and run them off the lead, or they'll be so much trouble due to pent up energy.
