So, until my son gets bigger, i wont allow him with them anymore without my supervision/me being with him at all times, til he is big enough to smack them/get them off him. Even when i smacked them both hard, they wouldnt let go til i really belted them both very very hard, and even then they tried to attack again. I couldnt farkin believe it. It went bad very quickly. If i had one dog only, the aggression would be less cause each dog wouldnt be play fighting with each other all day, so i am now wondering if getting brother n sister dogs at the same time was a bad idea.  I
