Bone and toy aggression is very common. The best way to deal with it is to monitor the two dogs. Give them both the same toy/bone and then sit back and watch. One dog will invariably try to take the other dogs toy/bone (very much like kids). When you see this start to happen discipline the dog that is ignoring their own toy/bone before he get to close to the other dog. Use their name and give a stern loud "Leave it" then pick up the toy/bone the aggressive dog abandoned and give it back to them. Continue this until they are both happily playing with their own toys/bones.
If you come into the room and they are already at each other yell at them both and then take the toys/bones away and put them out of their reach. Later give them back to them doing the above.
The above method has always worked for me.
Be careful to make sure that both dogs understand that you are the Pack leader. Trying to take a toy/bone away from a dog that feels you are equal can earn a bite. So you much establish dominance before the above strategy will work. Good luck.
