so i live out in the country but i sill have a neighbor bout 200yds down the road. he has a big husky dog that has killed both my rosters, my dog is a 85lb female German Shepherd. She will let him walk right up to the coop during the day and not do a thing. What breed dog is a good flock protector or how do i train my current dog to protect my chickens? She does run off all the coyotes, coons, opossums and such just not other dogs. Any particular dog breed that will get rid of every thing?
