That area is/was a hotbed for B breeders especially Keota and Stigler OK, just West of Spiro. There are/were several USDA licensed breeders in that area who bred Bs. I met some of them at the dog auctions. I think most of these breeders no longer breed Bs. There were also some Bs in a shelter near Spiro, a year or so ago perhaps longer. At least this girl is spayed so the breeders would not want her!
If you look in the Pedigree Database, there are a number of dogs with Keota in their name. Most of these go back to the WL kennel or other Bs the Choates of Tahlequah OK and others bought at the auctions. The Choates got out of the breeding business several years later and sold their dogs at a couple of auctions. I saw some of these dogs at the auctions.
