Now really, did you think anyone would say "no don't get her or you have enough already"? I didn't think so.
I see we have something in common. I have a mini schnauzer too, Missy Ann. She is 10 years old, diabetic and almost completely blind. I also have a 14 month old boxer, Rayna. All three are female, are indoor dogs and they get along great. So well that I once saw the boxer, yorkie and the kitten all eating out of the same bowl of food.
