@renaultf1:
Boy, I would think the last thing the owner would want to do was play any sort of tug-of-war games with the dogs/puppy in this particular situation. Nothing I've ever read about tug-of-war is about it being ok with specific breeds, but I have read that it does potentially encourage aggressive behavior…regardless of breed. I think YodelDogs hit the mark with the recommendation that either a behaviorist or the breeder should get involved ASAP.
I realize that tug-of-war games may promote aggressive tendencies :mad: but they are also an ecologically relevant outlet for dominance and aggression issues. Obviously, the tug toy should be completely controlled by the owner - stored where dogs don't have access, brought out and put away by the owner. Additionally, the owner should supervise the dogs with the tug toy. The aggressive dog can't bite/attack the puppy with a tug toy in its mouth (as the owner should present the toy to that dog first). The aggression could ensue if the puppy gets the toy first, that is why the owner must strictly control the toy.
I was only providing a few ideas and suggestions. Although not all of my suggestions may work in every situation, a behavioralist would provide a variety of suggestions as well and not every one will be effective. If the original poster doesn't feel comfortable with any suggestion from a fellow owner or from a behavioralist, then they definitely shouldn't try it.
