Curious - I'm a dog. What about my inner and secret animals?

I'm wondering; outwardly, I'm a wood Dog, but I have no idea what my inner and secret animals are, or how to work it out? Anyone care to help me?

I was born on 28th Feb 1994, at 22:07pm (UK GMT). I'm curious, would really appreciate someone telling me what my other zodiac animals are and what they mean. Thanks.
