Discover exactly what it costs to own a dog in your city.
We compile public federal and local datasets, document the scoring rules, and compare 15,684 cities on veterinary access, hidden pet taxes, breed laws, and outdoor freedom.
Most "Pet-Friendly" Lists Are Fake
Almost every "Top 10 Pet Friendly Cities" article you read online is compiled by an intern Googling "cities with dog parks" or looking at subjective Yelp reviews. They ignore the brutal reality that Breed-Specific Legislation (BSL) can force you to surrender your rescue in municipalities with active bans, or that rent-driven pet costs in San Francisco are nearly 3x the national median.
Tails.city is an independent publishing project that turns scattered public records into a readable city-by-city model. We publish the inputs, the tradeoffs, and the limitations instead of pretending the score is magic.

The 7-Axis Data Matrix
How we compare over 15,000 cities using published metrics, documented estimates, and explicit tradeoffs.
Vet Access & Costs
We use US Census County Business Patterns (CBP) to estimate veterinary-practice density from NAICS 541940 establishments, then layer in regional BLS CPI cost adjustments.
Walkable Climate
Processing 1991-2020 NOAA station normals to count "Walkable Days" (between 20°F and 90°F).
Housing Tax
Using ACS 5-Year Rent Data to model likely landlord pet surcharges and the broader housing friction dog owners face.
Breed Specific Legislation (BSL)
Tracking municipal legal databases for active bans and restrictions. Cities with hostile legislation are penalized, while states with preemption laws receive protective adjustments in the model.
FEMA Risk
Factoring in the FEMA National Risk Index for natural disasters requiring pet evacuation plans.
EPA AirNow
We penalize cities with excessive AQI "Unhealthy" days, a critical metric for brachycephalic (flat-faced) breeds.
How the Paw Score™ Engine Works
A fully transparent 3-step ETL pipeline powering our data.
Data Ingestion
We query APIs from the US Census, NOAA, EPA, FEMA, and BLS to assemble over 80GB of absolute ground-truth local data for 15,684 cities.
Z-Score Normalization
Each city's raw metrics (e.g., $1,200 median rent) are compared against the national median to calculate a standard deviation Z-Score, removing population bias.
Weighted Grading
The 7 normalized dimensions are composited using strict weights (e.g. 20% Vet Access, 10% FEMA Risk) to print a definitive Letter Grade (A+ to F).

Frequently Asked Questions
Clear answers about our methodology and data philosophy.
What exactly is the Paw Score™?+
The Paw Score™ is Tails.city's comparison model for dog livability. It combines public datasets from NOAA, EPA, FEMA, BLS, the US Census, and municipal code research into a directional letter grade from A+ to F.
Is Tails.city data free to access?+
Yes. Tails.city is a free publishing project built around public datasets, transparent methodology, and city-by-city comparison pages. Some metrics are modeled or estimated, and we explain those tradeoffs in the methodology.
Why do you include Housing Rent in a pet calculation?+
Because 'pet rent' and non-refundable deposits scale with local property values. If you move a large breed dog to a city with intense housing scarcity and high baseline rent (like SF or NYC), your invisible monthly pet tax can exceed $200. We factor this in via Census ACS data.
How often are the city datasets updated?+
We initiate automated ETL (Extract, Transform, Load) sweeps quarterly to fetch the latest CPI adjustments from the Bureau of Labor Statistics, updated Census demographic estimates, and changes in Breed Specific Legislation.
My city got a D-. Can I still have a dog there?+
Absolutely. A low grade does not mean dog ownership is impossible. It means the model sees more friction than the national baseline, such as higher costs, lower vet access, harsher climate, or legal restrictions. Always verify local rules yourself before moving.
