Giant schnauzers are tough dogs....we had a mix of G.S. and Labrador.....Biscuit....she weighed 95 pounds, & loved the kids...BUT, she was a great watch dog, very fierce when she needed to be...look carefully at them. Not sure the purebreds are friendly. There's always the spinone...big dogs, big goofs....at least FeeBee is....she loves everybody! And there's a breeder in southwestern MA.
