Q. & A. with Mark & Marilyn

  • Why did you start breeding?

    The program is led by Marilyn Griffin, who has dedicated her life to raising and caring for animals, incorporating her expertise in boarding, daycare, and farm management into her breeding philosophy. Green Acres Nextgen prioritizes health and temperament, conducting in-depth medical exams and selecting dogs with strong traits that make them ideal companions for individuals in need of a relationship-focused pet.

  • What makes your program special?

    Our dogs are known for their affectionate nature, adaptability, and child-friendly temperament, making them excellent additions to families. The program’s goal is to create a world where humans and animals thrive together, whether through therapy sessions or joyful puppy adoptions.

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

    Our Cavalier King Charles Spaniel puppies include ruby, tri-color, and chocolate. Golden Retriever puppies are golden. Colors will vary depending on the parent dogs.

  • Where do your breeding dogs live?

    They live in my home.
