If you have ever owned a pet you probably has looked over at your dog or cat and tried to figure out what they were thinking. In this case, Forrest the dog is on video sitting in his crate trying to figure out the math of the world. Since Forrest is a dog, you know the math has to do with things that dogs love. Things like trees, squirrels, and peeing on things. These are just a few of a dog's favorite things. We never know what our dogs are thinking, but we have a feeling it isn't too far off from what Forrest's owner thinks he is thinking!
