A fiduciary is a person or institution given the power to act on behalf of another in situations that require great trust, honesty and loyalty.
A dog's need to chew is instinctive and if you don't provide safe chews, puppies will chew whatever they find -- from your computer cord to chair legs. Provide inedible chews made for puppies less than 3 months old. Chews should not have pieces that can break off easily.
The best way is to remember that it is natural for dogs to chew. Don't chase your dog. Just trade the slipper for a toy he likes and as you trade, say, Thank you, puppy!. Your dog may make a game of it and start bringing you things.
