You should not be letting this happen. I will let the experts help you with how to stop it, but until then, stop putting toys down for them to fight over. While the dogs do set boundaries it is up to you to set the rules and enforce them. If you don't stop this now, it can get much worse with time. You can consult a trainer/behavorist for help. But definitely stop it now.
