Dogs have prey drives for small animals but that doesnt ever mean they wont go after a little kid.. I was bitten by a dog when I was 3 because the dog saw me running and attacked me for no reason, I was in my yard playing and he was in another yard with his owner. so I think even if you think your dohg wouldnt hurt alittle kid dont always be so sure if its a high prey driven dog. the dog that bit me was a black lab and my best friend had the same thing happen to her when she was little by a golden retriever.
