One day i was in the back stroking my horse when the hairs stood up on my skin. I felt something but heard nothing. I could just feel that something was amiss. So I started looking all around to see what it was I walked toward the front and saw a beautiful white dog entering the driveway. By the time I got to the front he was jumping all over my peacock cage. It did not disturb me because I knew it was very unlikely that he would get in because of how we made it.
I shooed the dog off. As he obeyed me and walked out the driveway, he had his tail between his legs and was hunching over looking very sad. I decided to call him back, and he came back. I went and got a rope and leashed him and carried him inside. Once I examined him I realized that he was skin and bones. If you passed your fingers over his back you could feel every rib indention. I gave him most of my thanksgiving bird, and he devoured it without even chewing. Also, he was filthy. He looked almost light brown though he turned out to be snow white once I bathed him. He has been with me now nearly a year and is now plump and happy.
To make a long story short, if my run for my peacocks was not strong, when this visitor came by, my dear feathered friends would have been dead. So we each have to do our own part. Not only do the neighbors need to keep their dog on their property but you need to secure your chickens too.
If you don't have them secured, unfortunately you have to take your lumps because anything can happen.
I would go over and see the neighbor.... crying and distraught. I would tell them that their dog just attacked your daughter, niece, grandaughter or whatever little female. And your husband came with the shot gun and scared him away. Tell them that he wants to shoot the dog if it comes anywhere near again but you cried and said no, don't do it. Ask them if they don't have a dog that looks like that one. Say "omg i hope it is not yours!"
Say "Listen, i am on your side, I don't want him to shoot your dog so you should really lock it up really tight because I can't stop him from shooting it if it comes around again and my husband gets in a rage.... I can't do anything!. "
Say " oh i am so scared! i don't want anything to happen to your dog. Please he didn't want me to tell you but I had to tell you what he is going to do so you could keep the dog hidden, or at least in your yard."
Give her a hug and let a tear roll down your cheeks. Say i had to let you know and leave.
If done right you can keep good will with your neighbors and get them to see how it is in their own interest to keep the dog in.
Good luck doing theatrics with the neighbor.
