Go w/ a mix if you want a mix. Purebreds are no better than a mix. They are easy to house train, and very smart. And if you go w/ a yorki-poo or whatever mix you have two great dogs rolled into one. Some people say they are healthier, and less expensive too. I have a Morkie, and she is the best !!! Housetrained, only have to say something once and she does it. Stays w/ me in the yard and does not run away......AWESOME DOG !!!!!!!
Whatever is best for you ...............
