Check the numbers yourself
Every figure on this site comes from these three files. They are free to download, and free to use if you carry the attribution the source license requires. Retrieved August 21, 2026.
What is not here
There is no row-level file. The cleaned records are one small decision away from being a list of individual animals and their neighborhoods, and the purpose of publishing is to let you check the arithmetic, not to hand over the dataset. Everything above is an aggregate.
The original records are public and anyone can start from them: NYC Department of Health and Mental Hygiene, via NYC Open Data publishes them under NYC Administrative Code 23-502(d). What is added here is the cleaning, the deduplication of renewals into individual animals, and the thresholds described on the method page.
The caveat that travels with every number
Around 80% of New York City dogs are unlicensed, and licensing is not spread evenly across the city. Every figure describes licensed dogs. Comparisons between neighborhoods carry that with them, and any honest use of this data should say so too.
