This is the same collie who played tag with the neighborhood kids and understood the rules. If you don't want to deal with the hair, get a smoothie.
My lab protects all creatures from harm...even the rabbits from our hound. The lab would never let anything happen to us, but he is a typical lab and I don't think he would be appropriate for kids under 10 or so. He's just big and rambunctious.
Whatever you get, make it black. For some reason, black dogs are more frightening than non black dogs. I don't get it, but they are.
