Search USDA-Licensed Dog Breeders and Dealers

Verify any USDA Class A breeder or Class B dealer against our mirror of the USDA APHIS public database. Search 2,837 active licensees by name, DBA, certificate number, or city. Every result links to a full profile with USDA inspection history since 2014.

What This Tool Does

This lookup mirrors the USDA APHIS Animal Care Public Search Tool (opens in new tab) , refreshed monthly. Use it to confirm a dog breeder holds an active federal license under the Animal Welfare Act before buying a puppy, selling to a dealer, or inspecting the facility's compliance record.

Two USDA license classes appear in results:

  • Class A — Breeder: Breeds and raises dogs on their own premises for sale. Required for breeders with more than 4 breeding females who sell dogs sight-unseen (online, by phone, or by mail).
  • Class B — Dealer: Buys and resells dogs — typically brokers who purchase from breeders and sell to pet stores, research facilities, or directly to consumers.

Certificate format: USDA certificate numbers follow the pattern XX-Y-NNNN — two-digit state code, license class letter (A, B, C, or R), and a sequence number (e.g., 43-A-6252).

Not finding the breeder? They may be exempt from federal licensing (four or fewer breeding females, or face-to-face sales only), licensed only at the state level, or operating without a required license. Check the state-level breeder licensing rules that also apply.

About these licenses: USDA Class A (breeder) and Class B (dealer) licenses are issued under the federal Animal Welfare Act and cover many kinds of animals — not just dogs (for example cats, rabbits, and other regulated species). A licensee shown here holds a USDA license but may breed or deal in animals other than dogs, so inclusion in this database does not necessarily mean the licensee breeds dogs. Always verify a breeder's species, status, and details directly with the licensee and with USDA APHIS (opens in new tab) .
