Yes, I'm familiar with how huge pyrenees dogs are. Lol
We had a Pyrenees/Hound mix and he still was about 125+lbs. He was beautiful. People thought he was a giant collie. lol
We now have an Anatolian Pyrenees. He's at least 150lbs. In fact, I'm a bit banged up after rounding him up day before yesterday. He wanted to run and I had ahold of his collar. I went down on my stomach pretty much ....pulled muscles, shoulder, wrist, back ....thankfully, after a couple days I'm mainly dealing with pulled muscles. lol
Thankfully, I have a secret weapon to getting him to calm down. He loves scratches around his ears. It puts him down on the ground like a big old baby! lol
