This is what I use to train EVERY pup that I am engaging with, regardless of age. It is my foundation for building an amazing relationship.
All puppies nip, it's a natural part of their growth process. Teaching them how to learn their bite inhibition while teaching them not to bite us is key to having us live happily together.
Your pup is going to pick everything up. Whether they bring it to you, play keep away or eat it is all in how you approach this behavior.
Knowing how to set up your training sessions along with how often to train is one of the of the "secrets of the trade" that is critical to you successfully training your four legger.
