Gus

Gus is a diminutive of Augustus, Gustave, or Angus — all names with roots in Latin or Germanic traditions meaning "great," "majestic," or "venerable." Augustus means "worthy of respect" from Latin augere meaning "to increase." As a nickname, Gus takes all that grandeur and makes it comfortable, the name you use when the formality of the full version would feel like too much distance between you.

Gus holds the #104 spot among US pet names, with nearly 975 companions sharing it. The name has a delightful combination of old-fashioned solidity and easy warmth. Gus suits companions who are reliably good company — animals who are present and engaged without demanding constant attention, those whose company feels comfortable and natural rather than performative. It is a name with real substance, and it tends to find companions who match it in steady, genuine character.
