As others have said. We nervously rehomed ours from the local farmer as she wasn’t as good as some of his other dogs at sheep duties. Without a doubt the best decision I’ve ever made though. She is a little timid (coming from a one man hill farm) but will happily run for two hours with me on the bike or conversely, will happily sit around sun bathing all day if needs be.
Her favourite place is in the back of the land rover though. A bit of an annoying habit – as soon as the door is open, she’s in.
I read all the horror stories of them being a real hand-full, and whilst they obviously have substance, not all dogs are the same. Luck of the draw I guess. Lets call it the “Great Collie Lottery”!
