I have two great pyrs and they are great. Scout is full blooded and Bella has yellow lab in her, but she is a guarding machine. They were rescue dogs I got as puppies in Missouri. They are absolutely the best dogs, love you to the death, and are wonderful with the Alpacas. We want more, would love to breed them, but not set up for it. They eat, but honestly my four little dogs eat as much a month as they do. I have one of those big several gallon feeders (can't be over 6 gallon's the way it looks) and I fill it 3 x's a month, sometimes 4, but there is always some left. I would guess between the 6, they eat a 50# bag a month. The Pyrs might eat 4 of the containers, and I fill it the 5th time, just never kept track, but I know I don't have to fill it every single week. I give them bones and snacky's too, so they are very happy with their food situation. In the winter I add a can of wet every other day to give them something else to keep the cold away, plus beat up eggs in powdered milk and give it to them for treats too a couple times a week.
