I need help finding a short animated film. It isn't well known, and I remember watching it when I was 6 or 7 back in 2009 or around that time.

It's a post-apocolyptic sci-fi based on a good sentient zombie with a pet dog trying to help a little girl get back to her family in a human settlement.

It was 100% fully animated.

I'm sorry, but based on the given description, I couldn't find an exact match for the short animated film you are looking for. It is possible that it may not be well-known or have limited availability. However, you can try a few methods to track it down:

1. Online platforms: Check popular platforms such as YouTube, Vimeo, or specialized animation sites, as they sometimes feature lesser-known or independent animated films. You can use keywords related to the film, such as "post-apocalyptic animated film with sentient zombie and dog," in your search.

2. Animation forums and communities: Engage with animation enthusiasts on forums or communities like Reddit, Cartoon Brew, or Animation World Network. Describe the film and ask for assistance in identifying it. Other users may have come across it or be familiar with similar works.

3. Other online resources: Explore websites dedicated to short films, animations, or even fan-created databases that collect information about various animated works. Review their libraries or directories, or ask for recommendations from fellow users.

4. Local libraries or film festivals: Check with your local library to see if they have a collection of animated films. Additionally, research film festivals that showcase short animated films, as they often present lesser-known or independent works. You might find it in their archives or be able to get assistance from industry professionals or festival programmers.

Remember, having additional details about the film, such as the name of the filmmaker, production studio, or specific scenes, can significantly increase the chances of finding it.
