If anybody ever has any canine issues weather chasing chickens killing or just harassment in general this is what u have to do this is the only sure fire way I know this have done it many times. If you're having trouble weather puppy or adult is wait till dark when the chickens are roosting and the canine is full from a good dinner anyway get a chicken down off the roost and go over to the canine and while still holding the chicken slowly remove the canines head and diacard. They may twitch at first and the more u do the easier it will get. If you adhere to these instructions you will not have any more problems with said canine. Remember this is the ONLY sure fire to to resolve canine issues. You're welcome
