I'm not an owner at this point, but does anyone have a Castro Laboreiro? The CAO looks very tempting, also. Those are the two I am leaning towards right now...but I LOVE the Great Pyrs. I need one very tolerant of kids(human) LOL. Also I have a stallion, probably two, as long as the youngin' still has great conformation... I need a dog that wouldn't challenge them...any thoughts? Oh, that and the birds and cats... Am I asking too much? Thank you.
