Q's on protectors here: We have a German Shepherd/Chow/Rottweiler mix who is the toughest dog on the block. When I am calling my horse and she doesn't listen, he'll nip her heels til she's by me. He loves the goats!!! And he will protect everyone on the property from strangers/dogs/wildlife. However I was wondering, do the protectors need to be in the fence with the goats? How many protectors do you need if you have say a very small herd of goats? Are there any alternatives to dogs?
