[quote1255278300=Hugo] Is this low prey drive a requirement to be a good LGD? Why? [/quote1255278300] Because livestock animals are prey animals, they will run on a daily basis. I see it constantly - one sheep gets spooked by something and takes off, the others will follow and there you have a running herd of animals. You don't want a switch turn on in the LGD's head - "they run, I should kill", because the dogs are quite large and strong and they are able to make damage. Not to mention baby-sheep-goats... they run and jump silly all day long. If you ever saw a bunch of baby-lambs - they are hillarious and entertaining, running around, jumping over each other. If you have a dog with prey drive - all these babies are dead seconds.
