Adynasty Tibetan Mastiffs

Adynasty Tibetan Mastiffs, Tibetan mastiffs, Wheaton, IL, serve DuPage County and the Chicagoland area near Chicago. Crystal Cosgrove has bred Tibetan mastiffs for more than a decade with membership in the American Kennel Club and regular health testing for hip dysplasia, elbow ratings and thyroid function. Puppies are raised in a mixed indoor–outdoor setting with year-round climate-controlled access to comfortable kennels and grassy yard space.

From the first weeks, each pup enjoys daily handling and introduction to household sounds, other pets and neighborhood walks to build confidence. Adult dogs in the kennel have earned titles as working livestock guardians and many pass temperament assessments for therapy work. Care includes monthly veterinary checkups, balanced diet plans tailored by weight and free roaming time under supervision. Throughout placement and beyond, guidance on training methods and breed-specific care is provided to support lasting family bonds.
