Jumping up is not so much a problem while he is a puppy however when he grows into an adult dog with these bad habits, you are going to find yourself being knocked over with the force of a small horse! Not to mention muddy paws all over your clean clothes, which is why it is best to nip this behavior in the bud while he is young.
Due to the nature of the training, be warned that his behavior may get worse before it gets better. He may think he is not jumping high enough to get your attention at first and may try to jump with more effort. Be patient though, this only means that you are well on your way to correcting the behavior.
Before training can begin you will need to get your hands on lots of treats and a clicker. Once you have all this in order, you are set to start training.
