Our neighbors dogs killed everyone of my chickens and 2 of my calves. I called the cops to do an incident report (for taxes on the cattle). The officer told us that we had the right to defend our animals by any means necessary(shooting them). I have had to completly start over with the chickens and it is VERY upsetting!
Oh honey...I am so sorry for your loss! If you have any proof that it was their dogs, please hold them legally responsible for it. Nothing can replace the upset you feel, but they tend to learn better NOT to allow their dogs to run loose wherever they want to go when they have a judge order them to pay the damages and keep their dogs in their own yard.
