As an adult, I've had three dogs. My wife assigned them each flavors based on their coloration and tendency to curl into a circle.

This one was just "powdered donut."

This one was cookies and cream.

This one was cinnamon. I feel bad using this picture due to using it in a recent RIP post, but he's demonstrating the donut pose.

edit: B-b-b-bonus! Though this one is a cat, she's smores flavored (and, unlike the others pictured, still around, though mellowing with age).
