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.
