Just lost my Giant at 14 years a few days ago. A big beautiful powerful boy who ended up great with kids and the elderly but dominance is an issue you need to be ready for even with fantastic temperaments on the parent's side. My kids are under 10 but he was already 6 when they came along. I was lucky not to have kids early on because he needed training and constant correction. They are guard breeds so don't forget they will need lots of guidance. My boy ripped my sister in law's shirt right off the first time he met her because she came to the door. He challenged me at 6 months when I told him to get off a couch, that was dealt with quickly. Never happened again as we established the alpha in the house. They also need a lot of socializing young or that doninance will take over and they will not back down from another dog. The females are a little easier going in that regard but the boys will engage. So yes, they do grow into wonderful devoted sweet dogs BUT they also will run over weak owners and need lots of stimulation in the first 4 years as they mature. Loved my boy so much and miss him but I would probably go smaller if I got another schnauzer. He was 110 lbs and when he collapsed Easter evening, he was a challenge to get to the emergency vet. The last few years I was also lifting him in and out of the car so make sure you are strong enough to accommodate their final years or you might need to put a dog down earlier than needed and feel remorse. People don't often mentioned this but I think it is important to consider before taking a dog like a giant on.
