This year’s picks show that classic names, like Max, Milo, and Daisy, continue to be dominant. Yet again, Luna is quite a popular choice for both cats and dogs. The moniker topped last year’s list from the pet insurance company Spot and has kept its place since. In 2023, the celestial name came in second place to Bella on U.S. News & World Report’s list of the most popular dog names. Now, canine owners generally prefer the name above all others.
