Little critters with big dogs are always a favorite here. I can use my dog for a pillow, but no one is around, to take a photo, when I get to lay my head on him.

In my experience, it makes for a much better rememberance of a special pet when the people special to that pet are in the photo. At that point, we're not just remembering a pet, but the pet's place in someone's life.
