Meet the breeder
I'm Jyl W., 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.
Q. & A. with Jyl
What makes your 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.What are the different breed coat types in your program?
Our puppies have stock coats. Coat types may vary depending on the parent dogs.What are the different breed coat colors in your program?
Our puppies include sable, black, black and red, and bi-color. Colors will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home.

Breeder-Reported Testing
Excellent level

Elbow Dysplasia Finals (OFA, BVA, SV, FCI)
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.
Cardiac Evaluation (rDVM, not registered with OFA)
Heart testing reduces the chance of passing down congenital heart disease, which can cause a range of symptoms ranging from trouble exercising to heart failure.
Temperament Test
A breeder may perform additional tests on their dogs that do not fall into these general categories. These tests may be more uncommon or very specific to a particular breed.
