How do you train a 6 month old dog ?!! HELP!!?

Well he's likely poorly bred since he's one of those "designer" mixes for one thing. Which with genetics considered can impact the intelligence of the dog. Even though the poodles are very smart, as well as yorkies.

What are you trying to train him to do?

Just basic obedience or housebreaking?

For housebreaking, get him a crate and branch from there.

For obedience, puppies in general have very short attention spans. So keep training sessions quick. (No more than 5 minutes) initially until he is able to pay more attention.

I would recommend puppy training classes for the obedience. As you will have a "professional" there able to aid you in what ever problems you may be experiencing first hand.

Go to a obedience class and it will help you a lot, it's good for the dogs to learn with distractions and the teachers will answer all your questions.

lil girl, I like the personality of a poodle. They are so sweet.
