The most popular dog names, ranked

If you have a dog named Spot, Fido, King or Rex, then congratulations: Your pooch is rarer than you might think.

Nowadays, that name ranks way down, at No. 99, on this list.  A dog named Pepper could add just the flavor your family needs. This Marvel-ous (see what we did there?) dog name has jumped a couple of spots — from No. 61 to No. 59 — since 2019.
