@weeziesmom:
I have tried chew bones to curb his chewing however he tries to take weezies and they fight over them
You can teach him to leave hers alone. Make them both sit for their chew; give hers first and make him stay with you when she dashes off to chew. {helps him see that she gets one/he gets one, and also gives her a head start!} Make sure he knows you have one for him also. He must sit and make eye contact with you before he is given his treat.
Once they both have a chew, make them stay in different spots. Stand between them, moving your body silently to block his attempts to get to her.
If necessary, tell him "no" or "leave it".
It shouldn't take long for him to learn that he gets his and she gets hers.
Eventually, he will just look when you hand her the treat and will sit and stare at your face until he gets his own, then he'll run to his own spot to chew his bone.
