ColColt, you'd be surprised to know how gentle the guardian breeds can be. Any dog can get annoyed and bite, even "sweet" breeds like Goldens and Labs. I see more fights at the dog park started by Border Collies and Lab mixes - most of the rotts/dobes/GSDs/etc. out at the dog parks (at least, in my area) are well behaved and very tolerant of other dogs.
I have two dobes and a corgi, and the dobes are great with Ada. My male adores her and her antics, and they wrestle daily. My older dobe ignores her for the most part, but little Ada seems to look up to her, and will follow her around like a shadow... Ilsa doesn't mind the attention and reverance at all!
Ada's motto is, "If your friends are taller than you, rise to meet them, physically and mentally!"
Proof:
Ada follows Ilsa around...
Ronin gets down to "her level" to play...
And just for a comparison... these gentle giants are very drivey, intense dobes. Here's Ilsa with her 6'5" "daddy"... "GIMME DA BALL NOWWW!"
