Boston Terrier Breeders in Missouri

Missouri has 738 USDA-licensed breeders — the highest count of any state in the country. A USDA license is required to sell puppies across state lines or to pet stores — these are typically the largest commercial operations and are subject to federal inspections.

Missouri also has 1,030 state-licensed breeders. Neither the state license list nor inspection records are publicly available — accessing either requires a FOIA request.

76 Missouri breeders have been flagged on the Horrible Hundred — by far the highest count of any state in the country and a key reason Missouri has long been called the "Puppy Mill Capital of the U.S."

Missouri breeders are spread across the state but are most heavily concentrated in the Ozarks region, particularly around Seymour, Lebanon, West Plains, Ava, Hartville, and Mountain Grove. You'll also find large clusters around Lamar, Jamesport, Neosho, Clark, and Cassville, as well as breeders in the Kansas City and St. Louis metro areas. Wherever you're located in Missouri, you can search any breeder's full inspection record before you buy.
