Training is a lifelong commitment, so there is no rule on how many lessons your dog will need.
Dogs, especially puppies, explore the world with their mouth. She likes to chew because it calms her. But it destroys your stuff. Even worse — she might eat something like a sock that could block her intestines. Break this habit now. Give her chew toys, and take away things she shouldn’t gnaw on. If you catch her chewing something she shouldn’t, say “no,” replace the object with an approved toy, and praise her once she’s chewing it.
Dog jumping while greeting is not natural. In the wild, dogs do not jump when they meet each other. Jumping is a learned behavior. Turn away if your dog jumps on you. Don’t give your dog attention unless he has his front paws on the ground. Then you can greet him and pet him. Or tell him to sit and wait until he does before you pet him. Try to keep your greetings low-key. That helps your dog learn to control his own excitement. Make sure he doesn’t bother or scare people who aren’t used to him.

Complying with the “come” command commonly goes unrewarded or has a low-value reward compared to off-leash freedom. Associating commands, putting on leashes should be a positive experience. Good Dog Sense understand the balance between obedience and reward.
