I'm Kristy E., the breeder behind Rocky Oak Cavaliers & Biewer Terriers LLC located in Oklahoma. We specialize in breeding high-quality Cavalier King Charles Spaniels and Biewer Terriers exclusively for loving pet homes. We also occasionally offer a hybrid Cavatzu (a Cavalier–Shih Tzu cross).
Our program is centered on exceptional health, sound conformation, and outstanding temperament. With 18 years of breeding experience, we understand how crucial early development is in shaping a puppy’s long-term well-being. All of our puppies are raised with ENS (Early Neurological Stimulation) protocols and are cared for inside our home, where they receive attentive, individualized nurturing.
Our goal is to provide families with happy, healthy companions who bring years of love and joy.
Q. & A. with Kristy
Why did you start breeding?
We began breeding 18 years ago after bringing home our first Cavalier King Charles Spaniel. We instantly fell in love with the breed and felt inspired to share this wonderful companion with others. Over the years, we also discovered the charming Biewer Terrier, another breed that captured our hearts.
Today, we are thrilled to continue sharing these sweet, loving puppies with families who will cherish them as much as we do.
What makes your program special?
We are proud to have seven generations of Cavaliers in our program, allowing us to closely follow and document health, temperament, and overall quality over many years. We are always happy to provide references upon request.
The well-being of every mother, father, and puppy is our top priority. While we love producing puppies that are adorable and true to their breed standards, health always comes first. Our commitment is to raise strong, healthy companions who embody everything these breeds are meant to be.
What are the different breed coat colors in your program?
Our Cavalier King Charles Spaniel puppies include blenheim, ruby, tri-color, and black and tan. Biewer Terrier puppies include black tan and white, chocolate tan and white, and blue tan and white. Cavatzu puppies include silver and white, blenheim, black gold and silver, and black and tan. Colors will vary depending on the parent dogs.
Where do your breeding dogs live?
They live in my home and a kennel on my property.

Kristi with Rocky Oak Cavaliers was very helpful and up front about our new puppy which we named Jasper. He is very active and as cute as can be. The first week he was very much about jumping on you and wanting to bite a lot, but now he is better and not biting as much. We love him very much already and consider him a part of the family.
Linda L.
Verified owner · Jan. 2025
Kristy was professional and experienced in breeding. She was very connected to us from the moment we reserved our puppy, sending videos, photos, and communicating with us. Her website is easy to follow and helps understand her strong policies about caring for the animals in her care. The vet was thrilled at how healthy our puppy was when we took her for her first appointment. We named her Georgie Girl. She is sweet and smart and a bit spicy when she gets going! We love her and thank Kristy for all her care. We recommend her to anyone. Thanks so much.

Rocky Oak Cavaliers & Cavatzus LLC is an AMAZING breeder. They answered all of my questions and concerns when purchasing my puppy Moxie May - Purebred Shih Tzu. She provides all the information to give you peace of mind. You can ask to receive weekly updates and she will deliver! :) Even though I never met my puppy before pickup day, I felt like I already knew her because of the videos and photos I received. Rocky Oak takes care of the pups for the first 8 weeks of its life - vet, deworming, training and entertaining. Even after you have your puppy in your possession, they will answer questions and concerns you have. :) I am so happy I went with Rocky Oak Cavaliters & Cavatzus LLC for my little bundle of joy. :)
