Ruth ranks at #868 with 136 entries, registered female. The name is Hebrew, from the Old Testament Book of Ruth, where it means companion or friend. On a pet registry Ruth functions as one of the most deliberately-old-fashioned female pet picks, sitting at the intersection of biblical-name and grandmother-name registers.
The grandmother-name register
Ruth clusters with Pearl, Mabel, Edith, and Vera in the deliberately-vintage female pet pocket. Owners pick Ruth knowing it sounds like someone's great-aunt — and that's the point. The cohort skews toward households who think it's funny to call a small dog with a serious adult human name.
The Ruth Bader Ginsburg overlay
For a slice of registry Ruths, the conscious reference is Justice Ruth Bader Ginsburg, who died in 2020. These dogs often come from politically-engaged households and were named in the 2020-2022 window. The name carries different weight in this slice — less grandmother, more legend.
Sound and breed lean
One syllable, with the long OO-vowel and soft TH-ending giving it a quietly dignified call shape. Not the punchiest recall, but distinct from any command word. The name lands hardest on small companion breeds — Dachshunds, Chihuahuas, and small mixed rescues. Browse the human Ruth page for the deeper biblical and SSA history.
