had 2 rotts and I had a little puppy show up one day at the back door, the rotts were looking at him I bet they were hinking well this ain't no bunny so we better be nice. The little guy was thinking he was a tiger, he snapped growled and postured. The rotts just said, ok what a putz. A couple years later if anyone came close to the rotts the little guy would bark grown and be the protector, he was some mixed rat dog and never got over 4 lbs. Was kinda funny. Looked like 2 yr old trying to protect Arnold.
Gotta love dogs.
