Grass? What Grass?

This is my backyard. Every year I try to grow grass and every year it ends up looking like this. I really don't know why I bother, because this is what happens when you have two dogs that happen to be border collies.Every year I throw down grass seed and fertilizer and before it even has a chance to take, my two knuckleheads have ripped it up by running back and forth chasing squirrels and each other. Oh the joys of spring...
