Nicole 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.
Nicole partners with buyers to find the best match as the puppies develop and their personalities take shape. Typically, matches are finalized when the puppies reach about 6 weeks old.
“My primary concern is that puppies are matched with appropriate families on consideration of their temperament and drive. We begin personality shaping at three weeks old, but by 6 weeks the natural characteristics become more evident. ”

“The puppy comes with AKC Registration papers, microchip enrolled in AKC reunite, 2 rounds of vaccinations, up to date ondeworming, health guarantee, towel or blanket with momma's/littermates smell.”
Nicole may provide a written contract or health guarantee when you purchase a puppy. This helps protect both you and your breeder, ensuring that you both have a clear understanding of the terms of your puppy purchase. If Nicole offers a contract or guarantee, the details will be personalized by them. If you have any questions or want to know more, don't hesitate to reach out to Nicole directly.
When you pay and communicate on Good Dog, you’re covered by Payment Protection.
You can drive or fly to pick up your puppy from Nicole.

Our family had such a wonderful experience working with Nicole. She is incredibly knowledgeable about the breed and helped us pick the perfect puppies for our family. She works a lot with the pups during the time she has them and they already knew a lot of basic commands when we brought them home. She has continued to support us with training issues and other questions that have come up. Our pups have wonderful temperaments and don’t mind being manhandled by our 10yo daughter. We truly couldn’t be happier with the experience we had with Nicole or with these amazing dogs!

Nikki was amazing to work with, low stress and she had the puppies best interest at heart. Luna had such a strong start on her training before we even picked her up, sit,wait and most importantly focus on me. Crate training was well underway and potty training. Literally it could not have been a better start. Did I mention the gorgeous dog who acclimated into the family from the start.
