Now this looks like a dog with a sense of humor. I used to have a German Shepard who was very smart. Whenever I'd throw a frisbee for him, he'd get so excited, he'd chomp on it - a lot - and perforate it so it wouldn't work anymore. I would have to get a whole stack of super cheap frisbees because they were one-time-use with him. We mostly stuck to sticks and balls, though.
