My Human has learned a new skill, one I find quite useful.
Once he is fully trained, I expect he will do it without being asked, but for now, I have discovered that once I empty my Kong of deliciousness, I can simply drop it on his foot and he will arise and refill it.
This afternoon, I learned that humans will occasionally dance on one paw and scream in pain when a Kong is thrown at them particularly forcefully. I guess he refilled that one while I wasn't looking. With a bone sticking out of the end. Oops. Next time I won't throw it so hard, it seems humans have sensitive paws.
