Sandy is a golden retriever who lives in California with her owner, Kailey Hopkins. A true beach dog, Sandy enjoys the sand and surf almost as much as Kailey does. If Kailey splashes into the ocean, Sandy is sure to dive in, too.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
