I also have no experience with dobies, but we have had big and small dogs for a long time. We had a big dog that was a german shepherd/chow mix (along with whatever else we don't know) that was 117 lbs. She was a very gentle dog and we never had any trouble with her and our yorkies. We also have a large yellow lab and never had any trouble with her and the small dogs either. Currently we have the yellow lab, 2 yorkies, and a maltese and they do fine together. Our yellow lab is getting old and occasionally growls at our 2 yr old maltese when she gets to bothering her too much but never gets aggressive. Now a human that messes with one of the kids will get bit in a heartbeat! So she's actually more aggressive toward humans than our other dogs. I think we will probably always have a large dog along with our small dogs.
