Nothing beats a Tibetan mastiff though, the ultimate night guard for a farmer. Their scent marking and barking alone will protect your property. They are nocturnal and prefer to be left outside all night to roam. They also live much longer than comparably sized dogs, up to 14 years. I got one after some coywolves were interested in my chickens and they were bigger than my beagle and rat dog. Worth the cost, now my only pests to deal with are birds and insects.
