I've been researching collies. I've heard that the smooth shed more than the rough coated. If anyone owns collies--how many times a week do you brush your rough coat? Is 1-2 times sufficient? I know one collie who has some anxiety problems and barks a lot. Her bark is so piercing--is that how all collies barks sound? And does your collie like the sound if his/her voice? I like quiet dogs, but appreciate a watchdog, but not crazy barking. Are they trainable to be on the quieter side, or is barking just a part of the breed that has to be accepted? Thanks!
