I have a Pyrenees/Lab mix. Sweetest dog ever.
He was born an old man. He moves slow. Not a deep thinker. Allows squirrels and birds to eat the cat’s food with impunity 5 feet away because he can’t be bothered to get up.
But let a person come near our fence at night and he turns into a killer, bark-wise. Deepest booming bark i have ever heard.
He is protective of our cats even though they disdain him, because he wants to protect something, ANYTHING.
That rescue dog is not a Pyrenees. He appears to be of the Spitz race.
My sister has a Pyranees. Sweetest dog in the world but takes no chit from other dogs or anything that comes on their property.
