My SIL who is an active duty AF bomb dog handler just recently adopted his dog who saved his life many times. She was having seizures due to the excessive heat and had to be retired. They had to bring her home with the muzzle on the first few times to see how she would react to small children (they have 2) and other dogs (they have a sm one). Needless to say she is wonderful the best dog I have ever been around. She obeys commands like you wouldn't believe! She doesn't like guns, not even play ones she takes them away from my GS and brings them to us and yes she has dreams sometimes but has never became aggressive. We kept her a few days while they were house hunting and she listens to us also.
