The video consultation platform FirstVet analyzed pet names from Hartsdale Pet Cemetery in New York to put together these lists of America's favorite cat and dog names. For the last 115 years, Princess has reigned as the top title for pets overall. Other royal names in the round-up include Duke, King, Lady, and Queenie.

FirstVet attributes the popularity of several names to pop culture trends over the years. Max became America's favorite dog name following the release of Mad Max in 1979, and the name Smokey began climbing the ranks with cats around the same time Smokey Robinson was climbing the charts in the 1980s.
