Different trainers have different methods for discouraging jumping. Some say when your puppy jumps up, turn your back and ignore them. Others suggest pushing or prodding the puppy off you, and using a command like, “off.” Whichever method you choose, remember that your puppy isn’t being bad. They’re just being themselves. We need to teach them the rules of the human world with patience and perseverance. Be calm, but firm. Always be consistent. Make sure everyone who interacts with your puppy knows to respect the same rules.

Biting. All puppies will nip and bite during play. If a puppy bites too hard during play, let them know they’ve hurt you. You can do this by issuing a squeal as other puppies in a litter might do, or by issuing a stern command like, “no biting.” Never lash out or strike your puppy, even when their sharp little teeth really hurt. When you see your puppy begin to bite more gently, or use a “soft mouth,” reward that behavior. It means they’re starting to get it. Socializing a puppy early and often with other dogs will help with the nipping. Puppies learn from each other how hard is too hard to bite.

Chewing. Puppies will be compelled to chew, which is not at all a surprise to anyone who’s raised a puppy. Stopping inappropriate chewing can be resolved, in part, by redirecting. Jenna Stregowski, RVM says, “Pointing your puppy to appropriate toys is another part of chew training. It's not enough to tell your dog no when he picks up something you don't want him to have. Instead, you need to redirect him to something he can have, such as a dog chew or a Kong.”

Training Methods
There are several schools of thought when it comes to training a puppy.

Some prefer dominance methodologies, where the person actively tries to become the puppy’s “pack leader” and then mimics behaviors a canine pack leader might exhibit to keep members of the pack in line.

Others prefer clicker training, which helps puppies associate desired outcomes with positive rewards like treats, and then a sound, till the behaviors are habit.

Still others are perfectly content to offer treats forever, ad infinitum, for a dog’s whole life, as long as the dog does what is being asked of them.

Whichever methodology feels right to you, they all seem to be effective when applied with consistency and love. Better one method than no method at all, which can lead to an untrained puppy who’s often getting scolded or punished for behavior they don’t realize is naughty.
