My dog was in our fenced yard. These other dogs belong to the neighbor who lets their dogs run wild. I've asked them to contain their dogs several times because they come to our fence and nip at people, pick fights with the other dogs, get in the trash, etc. I've also called animal control. Today just like I've feared my dog got out of the yard and killed the other dog. Well I assume she did because I can't find a body anywhere.
