They do consider the temperament yes, she told me they wouldn't keep a bad un and I was surprised to see all the collie types walking around and not feel threatened like on most farms.spot on gnipper, first time I went I had the kids with me, and first I was wary to get kids out as they ain't small dogs and all the shit people talk on here I questioned it. After seeing how they were their behaviour was spot on and great with my kids. Didn't see a single nervy aggressive collie there. Doesn't mean that you can't do a collie x head in or bad handling can certainly make them funny though in my op
