I'm sorry, but as a dog owner i feel it is my personal responsibility to make sure everyone is safe from her. if she bites anyone, i would expect to have blame bestowed upon me, unless of course the dog is defending me, my family, my property or itsself. and even if it was defending its self, i would still expect nothing more than a growl and for her to run away, rather than attack another living soul. My opinion is, the owner is responsible for a ) keeping the dog under control b ) educating the child on the importance of not opening the door and letting said dog out c ) ensuring the dog is not violent, and if it is, either have it re-trained or put down. It is also my personal opinion that if any of my pets shows aggression to a human, unless prevoked, that that animal will be put to sleep without delay. who knows what it might attack next! Anyone else got an opinion?
