Great Pyrs are a whole different breed of dog. I never would have believed it, growing up in northern NM with big aggressive coyotes, but we got a Great Pyr for our place. That dog was amazing. When he was about 2 years old, mabye - one day we looked out our front window and we saw him and 3 coyotes in the field in front of our house. My first reaction was panic, even though he was already twice as big as them. I ran to grab my gun. When I got back the 4 of them were running in a big circle each chasing the other. I was afraid they were going to get behind him and tear him apart. Then I saw the magic!!! That dog just poured on the coals and tackled the first coyote and fur flew and it didnt get up. The other coyotes saw what was happening and they took off across the field. My dog turned and ran, caught up with the 2nd coyote, fur flew and it didnt get up, then my dog looked up saw the other coyote and ran it down. Took the full length of the field, but he caught it and killed it too. Whole thing played out in about 2 minutes from the moment my dog first decided he was done playing till the 3rd coyote was a distant memory. From then on we knew he had it handled. He passed this year at age 11, under his favorite tree. He kept the coyotes away right up till the end. RIP Joe, you are missed!!!
