There was a show on pbs that i watched evey sunday morning. from what i can remember, it was about a big human sized dog (a man in costume) and it had real human kids, the dog did karate and wore a karate outfit and they would sing. now what will happen is they would fly on a flying carpet i think into a book and they would sing the same song every time they would fly on the carpet. i really cant remember much it was in the early 2000's im 18 now if you know anything about this show please let me know.
