I have 4 dogs. My two older ones, a pittbull/rottwiller mix and the other a chow mix just hate small children. I muzzle them when children are around. I have tried to get them use to kids but so far this has not worked and it is easier to muzzle them and be sure everyone is safe. It is not their fault because they have never been exposed to many people. For what time people are around I just muzzle or lock them in another room or let them outside. They are great dogs but not social. At 10 years old I know I will not change them..
