I've had Aussies since 1987 . I wouldn't have any other kind of stockdog(JMO, don't want to offend anyone). I had a black - tri male that I bought in California that was 45 Ranch & Las Racosa breeding. I thought he was an outstanding looking dog as a black tri. I trialed him in working dog & used him on the farm both.I lost my outside dog last year(he was a blue merle) & haven't replace him yet.) Right now all we have is a blue merle female that is a Mini & she is a inside dog. Smart as a whip & heels the girls when they start running thru the house, but I think if I took her to the barn & tried her on cows, only 1 of us would get back in the house( & I don't think it would be me).
