Peppermint registers 62 times at rank 1656 on female pets. It's a food-and-plant name that carries a specific sensory profile: sharp, bright, cooling, unmistakably itself. If the pet has a quick, bright quality that wakes you up, the name is working as intended.
The Patty Connection and Beyond
Peppermint Patty from Peanuts is the most famous bearer: athletic, direct, unapologetically herself. The name carries that energy. A female pet named Peppermint is expected to be confident, cheerful, and slightly chaotic in the best possible way. It also sits in the holiday-adjacent category: Peppermint is a winter flavor, making it a natural choice for pets adopted around Christmas.
Sound and Breed Fit
PEP-er-mint is three syllables and will shorten to Pepper or Minty in daily use. Both are perfectly good standalone names that give the full version room to breathe. The name suits female dogs with bright, alert personalities: Dalmatians (white with dark spots matches peppermint candy visually), Jack Russell Terriers, and any breed that moves like it's slightly caffeinated.

The Counter-Reading
Peppermint is a name that requires the pet to have energy. A slow-moving, contemplative cat named Peppermint creates gentle irony. For the right animal, the name is an accurate prediction of every morning for the next decade.
