My new idea:

As I started to make my original animation idea, I found it hard to do so I decide to change my idea into a simpler and short idea. My new idea is a man called Bob taking his dog, Dylan, for a walk but the dog is off its leader so it runs away. Bob starts to look for him. Meanwhile, Dylan is hidden behind the bushes and is hiding from his owner. Bob starts to get worried about what's happened to Dylan and starts to shout his name. Suddenly out of the blue Dylan appears and barks at his owner.
