Biting is natural for dogs. Dogs communicate with their teeth and their jaws. Your job is to train your puppy dog to use his teeth in a way that is safe for you, your family and society.
First, assert your mental and emotional dominance over your puppy as soon as you bring it home. In the dog world, the boss bites and is never bitten. Puppies are pack animals and will follow a pack leader. Before you start training your puppy, make sure that it sees you as the pack leader and that it is not trying to assert its dominance over you.
Do not let your puppy get away with everything when you bring it home. Set clear boundaries such as where the puppy is allowed to be in the house, when it is allowed to eat, and what it can play with.
If your puppy violates any boundaries, discipline it swiftly and consistently.
Secondly, if your dog bites you by accident. give it a clear "No!" if your puppy nips on you and give it a chew toy or bone to chew on and say "Take Your Toy."
Puppies like to chew on many different items when they're teething, so you have to teach the puppy that it cannot bite humans but that it can chew on many different toys that you give it.
I hope that this article helps your control biting in your dog.
