If you have goats, cattle,or sheep, you will need some type of dog to stay with them in the pasture. When we had to make this decision, we selected the Great Pyrenees and now four years later, we don't regret it for a second. Pictured second is Jake. He was our second addition and took a bit of training as he was not accustomed to working with livestock when we got him. Luckily for us we had already found 'The Dawg" pictured top.
