Zoe is a breed of dog known as Cavalier King Charle's Spaniel. She has purple fur with lavender fur on her chest, mouth, forehead, and eyelids. Her hair is a darker shade of purple with a single pink streak. She has turquoise eyes and her accessories include a black beret and a golden, jewel-encrusted collar. Many fans have noted that her hair and body coloring closely parallels that of the character Twilight Sparkle from the show My Little Pony: Friendship is Magic, also a Hub production. Oliver additionally provides voices for that show, including those of Princess Celestia and Cheerilee.
Zoe is a wonderful singer and knows it. She loves to tell people and pets how she feels about something even if it may hurt their feelings. The way Zoe acts resembles Rarity from My Little Pony: Friendship is Magic.
Zoe has a sister named Gail, who she loves a lot. Sadly, she has a hard time telling apart Chavalier K. C. Spaniels, which has caused her to mistake other dogs for being her sister at least two times. Gail is a friendly and outgoing character and seems to have a very strong bond with Zoe.
