Contact Border Collie Rescue groups--check online first. Border Collies have sssooooo much energy that many people can't handle it, so they get dumped. My
mix, Rose, is only 1/4
Border Collie, but she acts like she's full-blooded. At my place, however, she gets to run the 5 acres (and farmland in back of us) 1 or more hours/day, so I can kinda wear her out. Usually her attitude is "how many jobs do want me to do at the same time." They are a handful. They LOVE to jump, and to chase things, full tilt, like cars. They take their jobs REALLY SERIOUSLY. But, they're also sensitive, and won't respond well to physical punishment. (I like to crate her and isolate her there for a few hours if she's really been bad, like she's done something dangerous.)
Rose won't leave me alone if I haven't done my chores. On the other hand, though she doesn't like to be held, she sleeps touching me when I watch tv, or on the floor by the dining room table. I'm not a Border Collie expert, but I know some who are, and my dog is more Border Collie, than
GS or
Husky. So, if this is the type of dog you want, please find one that someone else didn't want.
