Kinsmen

Kinsmen Mastiffs, run by Mary Lynn Speer, is a preservation breeding program focused on mastiffs in Glenwood City, Wisconsin, in St. Croix County near the Twin Cities metro area.

Mary has been involved with mastiffs since 1988, making hers one of the longer-running mastiff programs in the upper Midwest. The program operates not as a kennel but as a household, with dogs sharing daily life alongside children and other animals — an approach Mary credits for producing dogs with the well-rounded, adaptable temperaments her breeding prioritizes above all else. Those looking for mastiff puppies in Wisconsin from a program with a strong show record will find that Kinsmen dogs have earned titles in AKC conformation, obedience, and rally, with at least one rally title on each dog in the program.

Mary also serves as president of the Mastiff Club of America and chairs its obedience and rally committee, bringing a national-level perspective to her work in St. Croix County. Clearances and individual dog dispositions are documented and shared as part of the program, reflecting a focus on the whole dog — structure, trainability, and temperament together.
