Your collie girl is just stunning! I love collies having grown up with one as an only child from the age of 3.5 to 17 years. I still miss her and I am almost 43. Of course I named her Lassie...*L* She was sable and white. As far as temperment so much of it depends on environment...but I am sure that any pup you pick out and work with will turn out fantastic.
