We all love our dogs and want to think that they're the most intelligent, the most caring, the most obedient... though some of us may be more right than others.
But get ready to have a little stab of dog envy - this dog is so well trained, she won't swallow the treat between her teeth until she is told! Holly probably graduated top of her class in puppy obedience school - like the canine Steven Hawking.
Admit it, this skill is useful - no more will your dog eat something they shouldn't! Do you think your dog can manage this trick?
