Robert (a leopard) is quite the character. He came from a circus that was shut down, and is best friends with Dakota. He, however, is even more addicted to cat nip than Dakota, and will do just about anything to get his paws on it.

Rocky (a wolf) is the son of Shadow, the alpha male of a pack that lives outside Dakota's Ridge. He first got into the park by digging under the fence to escape from Duke, a rancher's dog. Brought into the world of wildlife conservation 'life' by Dakota, they became good friends who like to pester each other and just about everyone else. Rocky unofficially joined Blazer's pack (one that's being brought up in the park), and have to constantly battle the fact that they think all humans are the best.Unfortunately, Shadow believes that his son is dead, killed by the ranchers and their dogs, and won't consider anything else.
He also seems to have a crush on Corky.
Sandy (a wolf) is Rocky's older sister. She still lives in the wild with her father's pack, so is slightly more built than Rocky is. She often visits the fence dividing the wild from the park, to chat with Rocky about what's been going on on both sides of the fence. When she goes back to her pack, however, and tells Shadow that she had been talking with Rocky, he only believes that she has created him in her mind because of her sorrow that her brother is gone. This isn't helped by the fact that Sandy keeps referring to Rocky being "on the other side".
