Meet the breeder

Q. & A. with Mad Hatter's

  • Why did you start breeding?

    I take great pride in raising healthy, happy, and well-socialized puppies. My passion for dogs goes beyond breeding—I am committed to providing each puppy with a strong start in life through proper care, nutrition, and early socialization in a loving environment.

  • What makes your program special?

    My goal is not just to place puppies in homes, but to connect families with lifelong companions. I strive to be a trusted resource for new owners, offering guidance and support even after the puppy goes home. Breeding is more than a profession to me—it’s a commitment to the well-being of each dog and the happiness of the families they join.

  • What are the different breed coat colors in your program?

    Our puppies include blenheim, ruby, tri-color, and black and tan. Colors will vary depending on the parent dogs.

  • Where do your breeding dogs live?

    They live in my home.

  • 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.

  • 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.
