|Species||Cavalier King Charles Spaniel|
|Family|| Zoe Trent (older sister) |
|Voiced by||Tabitha St. Germain|
Gail Trent is Zoe's younger sister, whom the group erroneously believed had been locked inside the Largest Ever Pet Shop. They then found out they grabbed the wrong dog, a male named Tootsie who only happened to resemble her.
As she's only appeared once, Gail does not have a lot of information regarding herself. She and Zoe appear to care a lot for each other, but she is easily willing to playfully admit how Zoe can make slip-ups.
Gail is a pink Cavalier King Charles Spaniel with lighter pink markings. She has the same body type as Zoe, and just slightly darker blue eyes. Her hair and ears are a shade of fuchsia pink with curly bangs in the center of her head, and she wears a gold collar with a small white heart in the center.
An image in a bonus in the Little Pets, Big Adventures disc potentially appears to be Gail Trent.
- Zoe describes Gail as full of "joie de vivre," which means she has an enjoyment of life.
