Daddy appearing 27 times in pet licensing data is almost entirely a registry artifact: owners who wrote a relational role in the name field, either as a joke, by accident, or because that's genuinely what they call the household dog in a multi-pet dynamic where one animal functions as the authority figure. It is not, in any realistic sense, a pet name chosen intentionally at the same rate as Max or Bella.
The Registry Artifact Context
Licensing databases capture whatever owners write. "Daddy," "Mommy," "Baby," "Sister," "Brother" all appear in municipal pet registries — not because owners named their pets these things formally, but because the field was filled in with whatever came to mind. Browse names chosen with more deliberate intent at pet names.
When It's Actually the Name
There is a small, specific tradition of naming a large, calm male dog "Daddy" — the patriarch of the pack who settles disputes and provides reassurance. Cesar Millan's pit bull Daddy, who helped rehabilitate aggressive dogs for years, is the most famous example. A pit bull named Daddy after Millan's dog is a real and affectionate tribute.
The Counter-Reading: Social Register
Introducing yourself as the owner of a dog named Daddy requires tone calibration. Some audiences find it charming; others find it confusing. Context is everything with this one.
