Getting 4 year old daughter dog for christmas which breed would be best?

we have been wanting a dog for a while now when my daughter was asked what she wanted for christmas a dog was her only request.. we live in a townhouse so we need something small when I checked the local paper for what was available for christmas the following breeds were peekapoo, shih-poo, poodle, shih tzu maltese mix, puggle, and chi-poo which of these breeds do you think would be best for a 4 year old girl.. I've always had bigger dogs so I have no experience with the smaller breeds and any information would be so helpful thanks
