Like Deb says, depends on the individual dog. It also depends on your nature. So it's a nature/nurture issue. My CC is very laid back, interested in meeting and greeting everyone. She's gentle and non-confrontational. BUT she is large, 11 months and 100 lbs. I expect her to top out at 120. Her brother is already 130.
She isn't aggressive. As for small dogs, she's fascinated by them, but they are usually aggressive towards her because of her size (they are afraid!)
Cats delight her, but they either run from her or make her sad by hissing and batting at her. She'd love to have a little furry friend and she tries to make friends, but so far no luck. Oh, she has many dog friends, just no cats (yet!)
I'd suggest getting to know the mother and father of the upcoming litter. Their disposition will give you a good idea. Bailey's Mom is a ferocious protector of her family, but once you are given the all clear, she's a enormous lap puppy or would be if she could get in your lap. We never met the dad, but his pictures suggest a calm, assertive, mountain of muscle that would would terrify any trespasser. The one son that we know is as sweet and lovable a creature as you could want. I expect he'll be as protective as the mom, but will continue loving on people because he has a sweet soul.
The rest is up to you. Nuture a secure, loving dog that comes from calm, secure stock, you'll get a great companion, a fiercely loyal protector and a best friend. Good luck.
