My mother-in-law's dog is driving everyone in the house nuts!  He is a Cavalier King Charles Spaniel (2yrs).  He will EAT anything from his chew toys to underwear (perferably dirty) to tissues.  Anything he can steal from whatever door is accidentally left open.  When he gets ahold of something that he shouldn't have, he goes bulistic.  His eyes get blood-shot and he growls at anyone who comes near.  We are afraid he will eat something that will harm him. Moreover, we are at a loss of how to handle him when he is in this psycho stage.  There are small children in the house as well and we want to protect them.  Help!!!!
