Meet the breeder

I'm Caroline C., the breeder behind Cornwell Labradors located in Longmont, CO. A dog’s personality is set by two things: the parents’ temperament and experience during critical windows, both settled before pickup. Here a canine social behaviorist runs both, from health-cleared, temperament-selected parents through every window. A puppy built for your life.

Q. & A. with Caroline

  • Why did you start breeding?

    Through behavior work. For years I helped owners resolve serious behavior problems, and the same pattern kept surfacing: the trouble had taken root in the dog’s first weeks of life, before their owner ever brought them home. Personality forms from inherited temperament and experience during early critical windows, both set at the breeder. I started breeding to work where personality is actually built.
  • What makes your program special?

    Puppy Structure, the development methodology I created as a behaviorist. Parents are health-cleared and selected for temperament, and each puppy is developed through every critical window on a plan built for the role they’re headed into: family companion, service, or ESA. Each goes home with a 10-week Puppy Structure guide for the windows still open at pickup. A Labrador built for your life.
  • What are the different breed coat colors in your program?

    Our puppies include black and chocolate. Colors will vary depending on the parent dogs.
  • Where do your breeding dogs live?

    They live in my home.

Getting a puppy from Caroline

Caroline has been certified by Good Dog’s screening team for responsible and trusted breeding practices. When you’re ready, reach out to ask about the puppies or anything else on your mind. You’ll get to know each other through messaging, phone, or video and pay securely, all on Good Dog.

After buyers complete the application and screening process, Caroline partners with them to find the best puppy match.

“Puppies are assigned early on from each family’s top-three ranking, pick order, and the role their dog will fill. Assignment happens early on purpose: the critical window is weeks two through ten, and we spend it developing your puppy for your household specifically.”

Price

Puppy prices include a $1,500 non-refundable deposit and $3,700 final payment, before taxes & fees.
Pay over time with Klarna.

“Your puppy arrives with manners already begun: potty training and basic obedience started by a behaviorist, plus AKC registered microchip, health records, and starter kit that includes food and littermate scented blanket. $1,500 reserves your pick position and applies in full to the total. Every family pays the same flat price, and every puppy gets the same behaviorist-led development toward their home.”

Breeder-Reported Testing

Excellent level

Cornwell Labradors reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Labrador Retrievers.

  • Hip Dysplasia

    Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.

  • 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.

  • Cardiac Evaluation (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.

  • Vet Wellness Exam

    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.

  • DNA Disease Panel, PRA, Rod-Cone Degeneration (PRA-prcd), Exercise Induced Collapse (EIC), Centronuclear Myopathy (CNM), D Locus (Dilute) DNA test

    Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).

    Caroline was very responsive and extremely educated on labs and gave me everything I needed to know on how to be a lab mom! It is also very obvious by the way my puppy acts that she came from a loving and structured home/breeder. Caroline even went out of her way to get my puppy acclimated to the airline carrier before flying home with me! She goes above and beyond to make sure her puppies are well taken care of and well prepared for a new home! I have had experiences with other breeds and Caroline outshines them all, especially with how hard of a time my puppy had leaving her🥹 because she loved Caroline. If you are between breeders, 100% lean towards Caroline's pups 🩷 my puppy adjusted so quickly and was so confident and happy and felt safe with me faster than any puppy I've experienced because of Caroline's hard work!!
