We have two yorkies. Darwin, 7 1/2 lb, Mabel just under 4lb. We also have a 3/4 pyrenees 1/4 lab, Zain who is approximately 130 pounds, give or take 10 pounds. It's actually Mabel who adores Zain and doesn't leave him alone. We never leave the yorkies alone with Zain but for us it works nicely. As for your Doberman, if she's anything like my Doberman Josie was, I can believe how gentle and loving she can be - friendliest dog I've ever known! Good luck and let us know what you decide!
