Check if your dog can safely move to your next city.
Before you sign a lease, compare 15,684 US cities on breed laws, pet rent friction, heat, air quality, disaster risk, and veterinary access.
Dog-Friendly Is Not the Same as Lease-Safe
A city can have parks, patios, and happy dog photos while still creating trouble for a real move. Lease breed language, local BSL, high pet rent, heat exposure, smoke days, and thin emergency vet access can all change the answer for your dog.
Tails.city turns scattered public records into a city-by-city risk check. We publish the inputs, tradeoffs, reason codes, and limitations so you know what to verify before you commit to an address.

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 Risk Framework Is Built
A transparent three-step pipeline behind the public dataset layer and the move / lease-risk checks.
Data Ingestion
We ingest source layers from the US Census, NOAA, EPA, FEMA, BLS, and municipal-code research to assemble the baseline city dataset used across 15,684 cities.
Normalization and Derived Signals
Raw metrics are normalized against national baselines and then translated into derived signals such as heat pressure, vet access strain, modeled housing friction, and scenario-sensitive comparison layers.
Risk Framing and Overrides
The normalized dimensions are combined with curated legal review, renter evidence, and field-level overrides to produce directional grades, city verdicts, and scenario-specific move guidance instead of a single friction-free “best city” claim.

Frequently Asked Questions
Clear answers about our methodology and data philosophy.
What exactly is the Tails.city risk check?+
The Tails.city risk check is a directional move and lease-risk framework for dog owners. It combines public datasets from NOAA, EPA, FEMA, BLS, the US Census, municipal code research, and field-level overrides into comparison signals and summary grades.
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 friction in a dog move check?+
Because pet rent, deposits, breed exclusions, approval gates, and no-pet listings often decide whether a dog can actually get into the home. A city can look attractive at a high level and still be hard to rent in with a real dog household.
How often are the city datasets updated?+
Refresh timing depends on the source layer. Core public datasets run on a periodic refresh cadence, while high-risk law and renter fields can be manually re-reviewed sooner when stronger local evidence or correction requests appear.
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 framework sees more friction than the national baseline, such as harder lease terms, higher costs, lower vet access, harsher climate, or legal restrictions. Always verify local rules and lease terms yourself before moving.
Check the city before the lease.
Start with the local rule, housing friction, climate, and vet-access signals that can change the move.
