Friend of mine had one of those growing up. Huge dog. Never forget seeing it pee on the hood of my friends car.
The dog just lifted his leg and was two inches above the hood. Good dog, but they didn’t train it well. He liked to pull riders off the three wheeler.
Three Great Pyrenees livestock guard dogs protect our livestock. They are magnificent creatures, entirely trained by loyalty and play instincts. Adopt them into the human family, their loyalty trait expresses.
Through denial of human affection the GP express a stronger play over loyalty instinct. After weaning each began living among the goat herd; learning and earning their place in the herd's alpha relationship structure.
Because overly protective goat nannies will head butt them when they begin playing rough with goat kids, every intruder is a "play" opportunity.
One GP will approach a coyote intruder to play, which disrupts the hunt. Mr. Coyote isn't interested in play, so Mr. Coyote seeks a meal elsewhere. Deer overpopulation caused a coyote boom. Resulting coyote boom brought in the apex predator, a mountain lion.
Few years later, we lost a pregnant goat. A few weeks later, our alpha LGD is badly mauled; most likely by the mountain lion. We haven't seen the mountain lion since. Chances are if the dogs injured her, she couldn't hunt; and coyotes would finish her off.
Cheers,
