Look it really is not rocket science... puppy does something bad you "correct" the puppy physically and verbally.
So that puppy won't do the behaviour again. There is no place in puppy's world for bribing, coaxing, begging.
To be a good leader you must be prepared to spending time with the puppy, being a leader.

BUT you can't do this until you have shown them what pleases you for them to do....
Is fetching a toy pleasing you ? Is sitting Pleasing you ? You figure out what behaviour you want from them and teach them it.

This way when puppy does something bad you can "correct" this and then engage in a behaviour puppy knows is good like fetch.

There are also simple behaviours you can start as soon as you get puppy home...

A Pack Leader always goes first. First when going through a doorway, first when going down or up stairs, and first when walking your dog. Your dog should be behind the pack leader at all times. While walking your Poodle should be by your side or behind you. Walks like this help release pent up energy in your dog. This is the number 1 way to communicate that you are your Poodles pack leader.

When you come into the house or the room where you dog is you should ignore the dog for a few minutes (even if you only leave the room for a minute).

Your dog should always have to work for a treat. A simple obedience command should be given before any treat is given. If she does not follow the command she should not be rewarded with a treat. The dog should always take the treat gently from your hand.

You should have set times for your feeding, feeding should be done on a schedule. Do not feed table scraps to your puppy. Poodles can have sensitive stomachs and if you deviate from her normal food and treats you will have a sick Poodle.

Just like the walking and going through doorways you should always eat first. The leader always eats first. When you give your Puppy food, eat a small snack first while your puppy watches before feeding her.

You should never allow your puppy to mouth or bite anyone at any time, including during play. Screaming and ending play will teach puppy this is unacceptable.

Your Puppy should not sleep in your bed, not only because there may not be room for you but also because in the dog pack the leader sleeps in the most comfortable place. This is not to say you can not ever allow your dog on your bed. You can invite your puppy to lay in bed with you but just make her stay at the bottom of the bed and not push you out of the way.

If you establish eye contact with your Puppy she should look away first. When the dog looks away first it reinforces your status as pack leader.

When walking your dog you should never allow your dog to "walk you". You should have a slack leash, not tight. Remember, the leader is always first and leads the way. When puppy pulls in one direction you should run in the other saying a command such as -watch me-.

One of the basic commands your Poodle puppy should learn is "drop it". What ever is in her/his mouth you should be able to take possession of at any time. Start when they are young pups and you can even have a treat ready to replace the item with. Make sure puppy obeys your command.

You should never play tug-of-war with your Puppy. This is a game of power and you may lose, especially if you have a big Poodle puppy, or you may end up getting hurt.

When you put your dogs food dish down make her wait until you tell her "Ok" to eat. Put yourself in front of the food dish and make her sit first. Remember, stand tall and think "Big" you are the pack leader. If the dog does not follow your command take the food up and try again in 15 minutes.

All games played with your Poodle puppy should start and end with you.

If you have a very dominate dog who has a problem with growling you should not allow them to lie on the sofa or bed. Remember, the leader of the pack gets the most comfortable spot.

NEVER EVER coddle a scared puppy no matter what the situation is. Always react confidently and upbeat and strong. This will teach puppy to also be the same way and will encourage your puppy to be a confident, happy self assured little puppy and adult Poodle.
