Q. & A. with William

  • Why did you start breeding?

    I began breeding Cavalier King Charles Spaniels after settling into my home, and over the years my experience has grown into a dedicated breeding program focused on health, temperament, and quality.

  • What makes your program special?

    My breeding program is built around health, temperament, and quality. I carefully select parents with strong bloodlines, including a champion sire, to produce well-structured, loving companions. Puppies are raised in a home environment and receive early socialization to help them transition easily into family life.

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

    Our puppies are black and white. Colors will vary depending on the parent dogs.

  • Where do your breeding dogs live?

    They live in my home.

    William was a pleasure to work with. He always responded quickly to my messages, questions and concerns. He was flexible in coordinating times to come to his home. He was even nice enough to provide me with a crate, a bag of food and a toy. The puppy he gave me is truly awesome. Happy and healthy

    Our little family recently moved across the country, as huge family people it was a very difficult transition for us and wanted to add a furry friend to share our endless love with. William answered any questions we had and made our process flow smoothly and answered every question we had seamlessly. The care for Chloe (originally Bella) and communication even after delivery is amazing, he truly loves what he does. He was willing to accommodate our needs and meet us half way. Miss Chloe is absolutely perfect and everything we were missing, we look forward to our future with her and are excited to see all the great things she learns and adventures she has.
