Dog lovers input sought

I'd like to get myself a dog as a companion. I'd prefer a medium sized, low/no shedding, mild mannered ( no yapping, no wild energy level) I'm not a huge fan of chihuahua or daschunds but I'm sure they're great dogs. I'd love to have a smart dog. I plan to keep the dog inside but I do have a nice , fenced yard.



Suggestions from the dog lovers would be appreciated ?
