It sounds to me like Duchess is playing, but her idea of play could be different than Coco's. Dobermans like to be in charge. When Mavis was around, even though at 80 lbs she was my smallest dog, she was Top Dog. She made sure the other dogs knew it by playing rough with them. It never was a real fight, but she got her point across just the sane.
At the Dog Park my guys play alot rougher with each other than they do with the other dogs. When they play with each other, you'd think they are trying to kill each other, but they are just playing. If your dogs get along fine, but play rough, I wouldn't worry about it. Duchess just has to make sure Coco doesn't forget who the Top Dog is.
It's a Doberman Thing.
