Three Rottweilers that belongs to our neighbors killed my chihuahua around 2:30am. They broke down a piece of the fence and went into our backyard. This is my fathers healer dog during his struggle with cancer so this has really hit home for my family. It was gruesome since we saw the three rottweilers take turn throwing our dog around and every time we tried to step out one would growl and come running to the glass door. Worst part is after the kill, were still trying to find their way towards us, going back and forth from the shed to the back to find their way to us. They never left our door step.... Animal Control came, but when he tried to contact the owner- they refused to answer the door. This is not the first time they got into our yard... I am so distressed, what can i do?
