We had a positive experience with MoonStar Farm! Caryn was very easy to talk to and work with. We have had our MoonStar Farm puppy for a month now and he is very healthy, intelligent, and has a great temperament. We are very satisfied with the experience all around.

I recently had the pleasure of welcoming a beautiful puppy into our family, and I can't say enough good things about the entire experience, thanks to our fantastic breeder, Caryn. From the very beginning, Caryn was incredibly communicative and genuinely excited about us bringing a new member into our home. Her enthusiasm was contagious, making the process even more special. Caryn provided invaluable advice about raising a Border Collie, which was especially helpful since it was our first time owning one. Her insights into the breed's unique needs and personality traits prepared us well for life with our new companion. Now, at five months old, our puppy, Aspen, has become an integral part of our family (or should I say our pack!). She is loving, funny, and incredibly intelligent—traits that keep us entertained and delighted every day. Aspen fits right in with our family dynamics, and her playful spirit brings so much joy to our lives. We couldn’t have asked for a better dog. Each day with Aspen is filled with laughter and snuggles, and we’re looking forward to many more years of happy memories together. Thank you, Caryn, for helping us find our perfect furry friend!
