TIP #1: PUPPY OR SHARK?
Has puppy nipping left you wondering if you mistakenly adopted a Great White shark? Smear some butter or peanut butter on your hand and every time your puppy licks it reinforce that behavior with plenty of praise and a tasty treat.
TIP #2: TEACH RECALL EARLY
A good recall cue is vital for safety of your puppy or dog in all environments, and the sooner you start teaching it, the more reliable it will be.
Most puppies will "come" to you whenever you decide to walk away because they instinctively like to follow you. The easiest way to teach your new puppy or dog the "come" cue is to begin using it as soon as you bring them home:
