Great Danes love people, and they usually want to show it by getting as close to you as possible. But because of their very large size, this can be dangerous. Not only can a large, heavy Great Dane knock a person over easily, but a Great Dane on its back legs is as tall or taller than a human. Because of their height, this puts their front paws, complete with claws, at face level! Injury from a misplaced paw on the face or eye can be serious.
Owners should train their Great Dane as a puppy, not to jump up on people as a matter of both manners and safety. Consistency is the best way to train your Great Dane puppy not to jump up, so this nasty habit does not continue on into adulthood. The trick is usually getting everyone in the household, including visitors, to adhere to the “no jumping” rule. After all, that Great Dane puppy is pretty cute, just remind everyone jumping won't be cute when he is full grown.
To teach your Great Dane puppy not to jump up on you, family members, or guests, you will need to remove the reward for jumping, which in most cases is to get as close to you as possible. Removing yourself from the situation when your puppy jumps up and not rewarding him with attention, even negative attention, will be key to successfully ending jumping behaviors. Avoid punishment, as even negative attention can reward an attention-hungry Great Dane. Teaching your Great Dane puppy an alternative behavior such as 'sit' that is incompatible with jumping is a good technique for managing jumping in a puppy. An alternative method is to make your young dog stand on his haunches, past the point where it is rewarding for him, so he avoids it in the future. This method should be used carefully, and by a handler that is used to working with young dogs, so as not to cause injury or fear, or reinforce the behavior. Remember, you are trying to discourage him, not punish or hurt your dog.
The most important thing to do in training your Great Dane puppy will be to get everyone on board. Consistency is very important, you do not want anyone to reinforce jumping by not sticking to your training plan. Using treats to reinforce alternate behaviors, such as 'sit' that are incompatible with jumping, will also be useful. Remember to be patient with your young Great Dane and avoid punishments that will confuse him.
