Finally found the Great Pyrenees I was looking for! Everest is a rescue, approx. 8 years old but in good health, and he completely ignores the chickens, even if he is in the pen with them. Hawks, beware!! We'll take care of the old guy for the rest of his life. He's a great pet and is good with chickens. Can't beat that.
It's always nice to see people rescue, especially when looking for a specific breed. Congrats!
