Denise Bosak

Denise Bosak raises Tibetan mastiffs in Cushing, Wisconsin, operating under the Northstar's Kennel name in Sterling Township, a rural area of northwest Wisconsin near the St. Croix River region and within reasonable distance of the Twin Cities metro.

The kennel's breeding program centers on maintaining and improving the AKC breed standard, with particular attention to health, structure, soundness, type, and temperament. All adult dogs are AKC registered and OFA health tested. The goal is to produce Tibetan mastiff puppies in Wisconsin that are both true to type and capable companions over a long, healthy life.

Dogs at Northstar's Kennel live indoors in a climate-controlled environment and have access to a large outdoor area. Puppies are raised in the home, given regular human contact, and begin sibling socialization between six and eight weeks before going to their new families. Denise also draws on a background that includes dog showing, training, and grooming, which informs how the kennel approaches early puppy development.
