Potato ranks at #660 with 185 entries, registered as gender-neutral on this chart. The name is the staple-tuber food-name pet pick, and on a registry it is one of the cleaner examples of the affectionate-food-name register: the dog or cat as a small, round, comforting carbohydrate.
The food-name pet cohort
Potato sits with Peanut, Bean, Noodle, and Dumpling in the affectionate-food-name pet pocket. Within that group Potato carries a particular squishy-and-round register that the others do not quite match: a dog or cat named Potato is usually being described as small, soft, slightly-shapeless, and entirely beloved. The naming is direct visual reference dressed in food-language warmth.
The shape-and-coat naming logic
A meaningful share of registry Potatoes are dogs and cats whose body shape resembles the tuber: stocky French Bulldogs, dachshunds with extra weight, round orange tabby cats, pugs, and Corgis with the famously-loaf-shaped body. The naming is the household joke about the pet's body type made into the registered name, and most Potato owners would happily explain the visual logic if asked.
Sound and the broader cohort
Three syllables, middle-stressed (po-TAY-toh), with open vowels and clean recall. The name carries warmly outside, though the three-syllable length means most Potatoes are also called Tater, Tato, or Spud at home. The food-name register has been growing steadily on registry charts since the 2010s as millennial owners lean into the affectionate-food-naming aesthetic. The human Potato page shows essentially no SSA presence; pet Potato owns the cultural space without competition.
