Welcome!!!
Hi! I have a gsd and a labx, love collies though.
I think the kong idea is a good one, definately ignore though because if you shout at her she will bark louder as it will seem like you are joining in!
Collies are so 'busy', you could try tiring her out on her walk before you want to get on with your jobs, i know it isn't always practical though.
Good luck on the forum, hope you enjoy, lots of people on here with lots of helpfull advice.
