Animal guides tend to come when you need them, not when you want them. I found mine in dreams. It was important to me that I meet mine, so that's what I kept on my mind as I was falling asleep for the night. Took a couple days, but finally it happened. And it was so cool!
Others say you can try to meditate, get yourself in that very relaxed state, and it might come to you.
Try either one, or both, to meet yours. But remember that you may not need one yet, so be patient. Blessed Be...
