As a dog lover you still need to remember that they are animals and a dog the size you were dealing with does not give you second chance with children present . Not saying that Cane Corso are more dangerous that any other but that type of dog in the peacefull city of san francisco killed a adult woman trying toget into her apartment . This was 5 or 10 years ago and the people that owned the dog were anything but steller citizens and had trained the dogs to be mean .Google the story and Cane Corso . What you did was the right thing keep an eye on them maybe leave the area but at some point you need to make it clear to the owner he needs to control his dog
