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.
Puppies seem to stay hungry; they're growing so fast that they need lots of nourishment. One way they tell grown dogs how they're feeling is by licking them on the mouth. The big dog isn't likely to feed the puppy -- that's your job -- but the puppy doesn't necessarily know that.
