I love huge dogs, and many of the giant breeds don't live very long. That's why I like Newfies and St Bernards. They live a pretty long time, as far as the big breeds go. I know they drool, but they are so fricking big it's worth it!
My favorite breed is a Collie, though.
She's 42 pounds, will be 5 on March 1.
She isn't a very calm dog either! We got into agility in self defense, to try to burn off some of that energy.
. . . you can see she is a little thing, only 20" at the shoulder, but boy can she hit those weave poles!
