Which Dog Would Be Good For Me?

I want a small dog — preferably under 12lbs when fully grown. I dont want him to shed, and if he is good for allergy sufferers, that would be great.
I want a dog that is loving, sweet, playful, not extremely hyper, but not a couch potato, doesnt require much grooming, doesnt bark much, easy to train, etc.
I dont really care if he is a hybrid or a pure bred, i just dont want to spend a huge amount of money on him ($300 max)
I also want him to be a little cutie that loves cuddling.
As of right now i’m thinking about getting a cockapoo, a maltipoo or a yorkipoo. Yes, i know that they are mutts, but who cares. And yes, i would check out local shelters first.
This is all of the details that i can think of right now.
So, which type of dog do you think would be perfect for me?
Any and all help is appreciated. And if you know any good sites, that would also be appreciated.
Thanks.
Oh, and yes – i asked this question earlier. I would just like more answers.
