Meet the breeder

I'm the breeder behind Dukenheim Kennels located in Napa, CA. We understand the responsibility of purposefully breeding in order to do better for the breed and the families that love them! We have spent years raising healthy and happy puppies! We are dedicated to building the breed by ensuring breed standards are passed down with each of our litters.

Jyl’s experience

  • About Jyl

    I have been involved with Working Line German Shepherds since 1995. I compete in IGP, AKC obedience, Rally. I have competed in dog sports most of my life.

  • What makes Jyl’s program special

    Our dogs temperaments are within the AKC and SV breed standard for a German Shepherd. We will not breed dogs that are outside of this standard. We strongly believe that a German Shepherd should be an all around dog and use this philosophy in our breeding program. I breed for CLEAR HEADED dogs! All of our breeding dogs are OFA hip, elbow, DM, and dental certified before being bred. They will either have IGP title, A.S. (American Schutzhund), an AKC obedience title or other working title before being bred.

    Elbow testing reduces the chance of passing down elbow dysplasia, which is primarily found in large breed dogs and can cause arthritis in the elbow joint and front leg lameness.

  • Eye Examination (rDVM, not registered with OFA)

    Eye testing reduces the chance of passing down a wide range of hereditary eye illnesses including retinal dysplasia, lens luxation, and glaucoma, which can cause impared vision or blindness.
