My bulldog is 1 1/2 and he is the same way! He has already bit my son's hand, he is 2. Then the other day he actually took off after the neighbor kid. She was playing in our sandbox and he ran over to her and bit her hand!! I've always had pugs...if I would have known that bulldogs even had a little chance of being aggressive towards children then I would have never gotten one. I would have stuck with pugs. All bulldog owners that I have ever talked to say how great their bulldog is with their children, etc...
