My husky will fetch twice. After that he looks at you like you're a moron. He'll fetch 3-4 times for my son and then he gives up and lays down. He does love doing obstacle course, training of any sort, dog park, or just playing with other dogs. And of course walks and runs. He does heel very well for roller blades and bikes too. Loves to wrestle too...mine plays pretty rough, but that's my fault. Super smart dogs...don't let all the "dog intelligence" ranking sites fool you...they don't always listen...but they are extremely smart. You won't keep him contained if he doesn't want to be...that's why you have to drain that energy, otherwise they will constantly escape(until they get a bit older).
