Experience

Karen has been involved with Leonbergers since 2007. She has raised and shown numerous Champions, Grand Champions, and Rally dogs. In 2018 Karen was awarded the AKC Breeder of Merit acknowledgement from the American Kennel Club. Karen invests a significant amount of time and energy into her puppies to provide them early neurological stimulation and safe socialization. This helps them grow into confident and well-rounded puppies, ready to go to their new homes. 

Happy, Healthy Bloodlines

Our Leonbergers are tested for:

Leonberger Polyneuropathy (LPN 1, LPN 2)

Leukoencephalomyelopathy (LEMP)



About Leos

As loyal a canine companion as any, the Leonberger is the perfect embodiment of the gentle giant. His love for his family is unparalleled, which combined with his powerful presence makes him a loving family member and stoic protector. In addition to his intelligence, the Leonberger is equal parts proud and independent, and requires structure and strong leadership to thrive. When provided this leadership, the Leonberger is a companion of unmatched loyalty, confidence and compassion.
