I have a Great Pyrenees on my property. He is on patrol 24/7 and loves his job. Early one morning I saw him actually run down a Coyote, grab the predators hind quarter on a full run, and literally throw him in the air about 25 feet over a fence. Haven't heard or seen one Coyote yelling at night or in the early morning since that incident. My Pry is a three year old, a mere 126 lbs., and runs like a small horse. He is also very alert to large birds that fly over the property.
I have a girl that is 110 lbs and a boy that is 150! They are very protective of their herd 🙂 but also very sweet towards humans. My boy reminds me of a horse when he runs too, I pick up his paws to trim his nails the same way I would a horse, lol.
We had some neighbor kids that would ride a 4-wheeler up and down the fence line and taunt them when they were puppies. I asked them to stop, they didn’t, and then I talked to their parents... still went on. We ended up installing a privacy fence along that line. I was worried the pups would scale the fence and a kid would get hurt, and also that the taunting would make the dogs mean. Fortunately, that didn’t happen. My other neighbor has very sweet kids who bring them treats so they like kids now
