Nancy, Sonny would want you to have someone to love just as much as you did him. He knows how sad you have been and wants you to be happy, both that he is out of pain and that you have someone to care about.
I don't know about the mix you are mentioning, but my mother had a schnoodle (schnauzer/poodle) she got from a shelter, and it was about the sweetest, smartest dog you ever met. And, because of it being part poodle, it did not shed!
As someone said, just open your arms and heart, and you will have honored Sonny's memory by continuing to share your boundless love.
