killing chickens

[trisha_hern]

A member of my family found a dog about a year and a half ago. and from the beggining i noticed some serious aggresion. she snapped at the young chidren.
she began attacking my dog and now she's killed 2 of the neighbors chickens and there was blood shed. i don't know what to do i'm worried she will bite me or another member of the family.but the owners aren't takeing it serious they say "it's not her fault"nthis dog is full grown about 4yrs. old.
