my mum wold agree this.her dog was a bit hard to take into places like pets at home because if a kid tried to touch him he would bark and then she would get worried and nervous.she bought a little muzzle and knew it would build her confidence in bringing him out amongst kids more.he needed to learn that people werent bad andnow she doesnt need it.it took a little time but now he can be around people and not be worried.
