Rivera at rank 1,491 with 71 records, gender-neutral, is a surname used as a pet name — and at this tier, that almost always means tribute. A dog named Rivera is almost certainly named after a specific Rivera: Diego Rivera, Frida Kahlo's husband and the muralist; Mariano Rivera, the legendary Yankees closer; or simply a family name that held sentimental weight.
Surname Transfer as Tribute
Surname-as-pet-name is a specific naming tradition, more common at the lower end of the registry where deliberate, personal choices live. Rivera is Spanish in origin, meaning "riverbank" or "one who lives near a river," and it carries the particular resonance of a recognizable Latinx surname. Owners from Latinx families naming a dog Rivera are often doing something similar to owners who name dogs after their own last name or a family name they want to honor.
Diego Rivera Connection
The muralist Diego Rivera is the most culturally loaded single Rivera for American audiences, particularly following the Coco and Frida cultural moments that brought Mexican art and cultural history to wider attention. A dog named Rivera in 2020-2024 may well carry the warmth of that cultural moment, even if the owner's primary referent is a baseball player or a family member.
Sound in Daily Use
Three syllables — ri-VER-a — with a strong middle syllable that projects well when called. The trailing A gives it warmth. It's not the most efficient name for across-yard calling, but it's distinctive enough that no other pet at the dog park shares it.
