Napoleon (1997)

Muffin is a gentle golden retriver puppy who dreams of becoming a fearless warrior named Napolean. During a children's birthday party "Napolean" seizes his opportunity to search for adventure when he jumps into a birthday basket to which several balloons are attached. Soon the puppy is whisked away towards the Australian outback where he must learn harsh lessons about life when he is forced to defend himself against wild dingoes, snakes, lizzards and other scary creatures in the bush country before he can find his way home again.
