Key Finding
The headline decline from 211,104 dogs (1979) to 42,880 (2024) masks a structural shift: teaching and basic research use shrank dramatically, but regulated toxicology testing — the core of beagle demand — has actually increased.

Dogs in US Regulated Research, 1973–2024

From 211,104 at peak to 42,880 — but toxicology use has increased

The headline decline masks a structural shift: teaching and basic research shrank, but regulated toxicology — the core of beagle demand — grew.

Note: Pre-2016 values marked 'medium' are derived from NRC compilations. Pain categories available from 2022.

How Dogs Suffer: USDA Pain Categories

FY2022–2024 — Column E (unrelieved pain) increased 20% from 2022 to 2023

The 410 dogs in Column E experience the full toxic effects of test substances — nausea, organ failure, seizures — without any pain mitigation.

Data Gap
Most jurisdictions track "dogs" not "beagles." Great Britain is the only country that reports breed — showing 97.3% beagles (2004) and 94% (2024). The true global beagle count is unknown.

Dogs Reported by CRO (USDA Data)

Most recent available USDA annual report data per registration

These are the only publicly available dog counts for CROs. No CRO discloses beagle-specific numbers. The actual global total is higher — these are single-registration snapshots, not enterprise-wide counts.

Note: USDA reports 'dogs' not 'beagles.' SNBL transferred US operations to Altasciences ~2018. Inotiv/Envigo ceased Cumberland operations Sept 2022.
