I've never personally owned a Border Collie...
As far as herding dogs go, I've had a Chow Chow/Australian Cattle Dog mix....
However, they are extremely popular in the town near where I live as many people here are ranchers. (Not including myself...as I refuse to eat red meat.)
Border Collies are most popular here followed by Australian Cattle Dogs, and there are a few Australian Shepherds.
So the Borders here get to do the work they were bred to do! The sad thing is, many people here (well not where I LIVE, but in the neighboring town) are as well bad dog owners, which is awful. Many actually kick and beat their dogs and PUPPIES, even the kids do!
I witnessed a boy no older than 9 calling his Border Collie (mix?) puppy towards him and then KICKING her as hard as he could when she approached. I chewed him out.
Not many people there are in this time and age, nor are they very well educated...to say the least.
ANYWAY, Borders are very intelligent dogs! I have always wanted one, or an Australian Shepherd, but we are afraid they'd get out and cause trouble with the livestock near by (a few miles distance)...
