I mention this a lot, but my dogs are very hyper, high-energy dogs. One day, my dog was going crazy as per usual, running all around the house like mad and running in and outside the house as fast as he could. But...he wasn't paying attention much, so he ended up running right into the screen door, putting a large dog-sized dent in it. We laughed at him and felt sorry for him at the same time. Luckily, he wasn't hurt, and he actually only acted confused about the strange force field in his way. Then we opened the door for him and he took off running like crazy again as if nothing had happened. He's such a smart dog sometimes...other times, not so much.
