disctract her (a lil tug on the leash upwards or sideways not backwards)... and once she does and is quiet.. give her a treat.. so she associates being nice and quiet with treats.. then increase the time she has to be quiet and behaving...

have her sit in silence ans give her treats...

if you can watch Millan it should help.. as I´ve seen a few cases like that...

with my own.. I just shush them.. no need to yell or anything just shhh... and now with the huskies which are so very vocal I´ve been redoing it as they were out of control once I got back and are now getting the idea... so if a husky can be quiet I bet yours can too
