We are between 4 houses, but I hate the nights I can hear the spine chilling cries of a pack in the fields around all the houses. We have 5 foot small weave fence everywhere, even over the gates, but I still worry. Alpacas don't defend themselves. I want a guard LLama. lol. Our dogs go out in the fenced yard, and I think the pee smell of five dogs, and whatever guys are drinking beer at our house would keep them away, (yes I said that), but it is still an un-nerving sound. Our chickens are up tight, so I don't worry for them as much.
