Patrick ranks #831 with 141 male registrations. The name is the canonical Irish saint-name and it sits unusually formal on a pet license: most household pet names skew shorter and more diminutive, but Patrick on the paperwork suggests deliberate choice of the full form.
The full-form Irish register
Patrick derives from Latin Patricius ("nobleman, patrician") and carries Saint Patrick's full Irish weight: the fifth-century bishop credited with bringing Christianity to Ireland, and by extension the cultural pillar of Irish-American identity. On pet licenses, Patrick lands disproportionately on Irish-American households and on pets adopted around or named in honor of March 17. The Irish setter cluster shows the strongest concentration.
Sound and call-name reality
Two syllables, front-stressed (PAT-rik), with a hard P opening and a sharp K close. The full Patrick calls clearly outdoors but most households collapse to Pat or Paddy within the first week. The diminutives carry their own register: Pat reads as middle-American casual, Paddy reads as overtly Irish. Patrick on the formal paperwork signals the household wanted the dignified version on record.
The counter-reading
The honest concern is the strong human-coding. The human Patrick page shows top-100 SSA presence across decades, and the dog will share call-name space with substantial human numbers. Households who want the Irish register with cleaner pet identity might consider Finn or Murphy, both of which read more decisively as dog names.
