Doxies are great dogs, but...
They can be barkie. My two will bark at the wind blowing. Max, my 12 yr old loves to hear himself bark at nothing. And they do have a large bark for such small dogs. But as with every other breed this is not necessarily typical.
Another suggestion would be to check out rescue organizations. There are rescues for just about every breed of dog. I've done rescue for yorkies and doxies. These are mostly adult dogs who need a loving home. And being rescues, they are so grateful to find a loving home.
