I agree that it is very important to teach your dog to be patient. Especially when you have a large dog, if they learn to jump and bounce around, they will soon start knocking over things in their excitement, and sometimes, they will even knock over the person if it is a large enough dog, and he jumps into you just right.
I have a very good friend who had to end up giving away her large dog just for that very reason. He was an outside dog, and had a large kennel and fenced in part of the yard to run in; but when she went out to feed him, then he would get excited and jump around and one day he knocked her completely down on the ground, and then he was pawing and digging at her once she fell down. She was unable to get back up because the dog kept jumping on her, and she ended up badly scraped and bruised from the experience.
Her son had always taken care of the dog, and then he got sick and died unexpectedly, and she was left trying to take care of the dog.
If he had been properly trained, none of this would have happened to her, and she would have been able to keep the dog.
