Q. & A. with Nancy or Katrina

  • Why did you start breeding?

    1998 we had a friend that was a breeder and later met Judy Vickers which has been an awesome mentor even to this day. Both of these ladies taught up that with passion and hard work with excellent bloodlines you can produce Sweat Heart Cavaliers!

  • What makes your program special?

    We have a network of 6 Breeders that breed with the same bloodlines. This gives us a wider range to evaluate the health of our bloodlines.

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

    Our puppies are blenheim. Colors will vary depending on the parent dogs.

  • Where do your breeding dogs live?

    They live in my home.

    Katrina was quick to respond to my inquiry. She was very nice and great to work with. She gave me a lot of useful information to help with raising our puppy. The puppy is so sweet and has made himself at home in our family. I would highly recommend this breeder.

    Sir Charles Barkley is the most well behaved puppy we have ever had! We are over the moon with our new addition to our family. SCB is doing awesome on his routine and absolutely loves his sister Penelope, talk about best Christmas ever! He is the best traveler. He’s already been to Oklahoma with us. He loves to nap. His favorite toy is a squeaky squirrel. My husband hopes to teach him how to keep squirrels away on our property.
