Meet the breeder
I'm Katherine W., the breeder behind Thornfield Farm Goldens located in Groton, NY. When I bring a litter of puppies into the world, I take that responsibility seriously. I do everything I can to make sure the pups get the best start possible, starting with responsible breeding. Any pup or dog from my program is a part of my family. I have a home for them here if they need it.
Q. & A. with Katherine
Why did you start breeding?
I have always loved puppies. As I child in rural 1950/60's Illinois, I helped neighbors with their "accidental" litters. I breed because I love raising puppies and experiencing the early developmental puppy stages. My background in genetics made me very aware of the pitfalls of mindless breeding. It was important to me to learn about structural, and eventually genetic, testing and clearances.What makes your program special?
The puppies are raised in my house. Several rooms become the Romper Room, furnished with beds & baby agility-type equipment. Potty areas are kept very clean. In warm weather they have extensive fenced outdoor space. They are handled gently, appropriately & often by friends & family. I breed few litters. I spend hours with the pups in my care. Each pup is a well known and loved individual.What are the different breed coat colors in your program?
Our puppies include dark golden and golden. Colors will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home.
