Meet Zeus, our 9-month old Great Pyrenees/Anatolian Shepherd mix. (The kids named him; they have been going through a huge Greek Mythology phase lately.) He is large (62 very fluffy pounds) and still growing but I don't think he will be enormous like some Pyrenees and Anatolians are (especially the males).
Zeus is perfect in all the ways I need him to be perfect: he loves children, he loves adults, he loves other dogs, he tolerates all other species with the utmost patience (even our cat Lupe, who is Not Very Nice), he doesn't pull on the leash, and he is extremely fluffy.
He does have a penchant for chewing anything around him (including the window sills) and he will steal any morsel of food off of table or counter top (and he is huge so it is easy for him to reach it). I can work with those things, though. Really, the fact that my kids can just wrap their arms around his fluffy bulk and love on him is the best. Big Sister's soccer teammates adore him, as do all of the kindergarteners at Brother's school. He is one of the gentlest dogs I've ever known.
Welcome to the homestead, big guy!
