Obsessive Compulsive Dog

So the puppy is finally starting to figure out that poop and pee goes outside. She's even picked 2 favorite spots. What's funny is that she doesn't seem capable of going unless she and I have played soccer. I take a blue soccer ball and I'll kick it over the house or down to the lower lot and she will take off with exuberance to find this ball. She'll run down the hill and bring the ball back to me. I'll kick it a second time and she'll return holding this blue soccer ball in her mouth but this time she'll bypass me and go to her spot. She won't let go of the ball while doing her business. It's the funniest sight! Of course it only makes sense that our family would end up with a dog with rules and rituals.
