If you're fencing anyway, and you want a dog on alert both night and day, you would need a pair - they would then be able to take turns napping while the other was watching.We are in the process of installing a 6 ft tall chain link fence around the entire area and then will be running a hot wire around the entire enclosure but also wanted to back that up with a guard dog inside the enclosure. Was hoping someone had some experience with a specific dog breed that worked best for them. I guess I will just continue to do research and hopefully pick a winner that with proper training will be the added protection we are looking for. Good luck with your LGD. Please keep me updated on how things progress. Thanks for the input.
The breed is kind of personal preference and what you have available within your preferred travel distance. Anatolians are good, GP/Anatolians are good (this is what I have), Maremma, Karakachan, etc they're all rather similar. You would want a male and a female pair, or two males, but definitely not two females. Some people make it work but female-female aggression is real and can be deadly. Preferably try to find adults, at least an adult female - you need something ready to work (over two years old) and also you really want to wait to spay/neuter the giant breeds until they're fully mature at 2, and it's easier to have an intact male running around than a female going into heat calling dogs and coyotes from up to five miles away.
I would get your chainlink up and run electric both inside and out if you want dogs, on top and then close to the bottom because they are digging and climbing machines.
