RE: my dog bit my daughter...
Read again what DocE wrote. I have done this with everydog I have ever had. I feed them and then tug the tail rub their ears or just pet them. I know that almost all pups sooner or later will bristle up or snap at me. When this happens I grab them by the nape of the neck pick them up by the nape and growl NOOO in their little faces. One time like this will usually let them know their place. You don't have to kill a pupu to get your point across. You can't do this to a child but it certainly works well on a pup.
