I would go with German Shepherds they do shed alot...but they are love bugs...here is mine with Lexie and now..and for a watch dog, you already got them girl, my yorkies make more noise than my 125 lb shepherd.

I don't have any recent ones of Max and the yorkies, the boys go out and I am sorry to say I don't have time with the camera due to the fact I watch them really close, they can go thur my fence and they are always having a pee party, see who can pee on the bushes or fence the most.
