A friend of mine on Face book has a White Swiss Shepherd that is chasing and killing Sheep. She lives in Europe if I remember correctly. Anyway the dog doing it is a young male. Just over or under a year. She is looking for suggestions on how to stop her dog from doing this. Since I have never had this issue I have no idea where to begin other then to tell her to confine her dogs or keep them leashed. I don't know much of the details surrounding it. She just commented on a post I put up of my girls and made the statement that she basically needed help with teaching her dog to not kill sheep. So I thought I would ask you guys to see if you have any tips.
