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.
For older puppies (around 6 months) this is a sure fire technique to stop puppy mouthing. Put a pinch or choke collar on your puppy and each time he bites you give the lead a short sharp tug. This correction will form an unpleasant association to your dog every time he bites you. It won't take him long to stop.
