Hi Steve,
Re-entering a dream to explore it is one of the main techniques Tony uses to get the depth of meaning from the dream. It does take practice, but don't fret over it. Simply practice going back in and picking a character or an object in the dream and enter the exploration from that point of view. If you meditate, it is something akin to that state...quieting the mind and setting your subconscious free to surface things. Tony has written more on the website about how to do this.
I have sent him a note asking him to look at your dream. If he doesn't get to it in a few days, you can post the dream again and I'll stay off the thread.
I love the relationship you seem to have with animals in your inner life. You might want to look at books by Ted Andrews, especially Animal Speak, or the Medicine Cards which is a book and card set by Jamie Sams and one of my teachers, David Carson. I think both have websites you can browse also.
Keep dreaming!
