It is easy to spend your time reacting to your dog's unwanted behavior. For Example...
- Yelling "No!" after he has tipped over the trash
- Calling "Come here, boy" after he sprints out the door
- Commanding "Off, off, off" after the dog's paws are up around your shoulders
After is too late.
You need to anticipate your dog's behavior and take action accordingly. Your puppy is predictable. You know that he will jump on guests, pull you out the door and try to steal the cat food. This is not news. That being the case, why not make a plan for success?
Set up the situation, leave the lead on the dog, and teach him. Use body blocking to prevent jumping or racing out the door. Work on sit as the answer for almost everything! As your guest enters, command "Sit." As you reach for the doorknob, tell them "Wait." As he turns his head toward the cat food, issue a no-nonsense "Leave it" then back away, help him get it right then throw a puppy praise party! Always praise/reward lavishly when he complies.
