I had the most positive experience working with Sergio! Communication was easy from the beginning to end! He was very knowledgeable about the breed and I could tell from experience that his dogs are well loved and cared for! I would not hesitate to purchase more puppies from him in the future! We brought our new puppy home a few weeks ago and he is thriving! Thank you Sergio!🩵

Sergio made the experience of getting a puppy for the first time very smooth and simple. He took great care of my puppy before I received him. It has been a few weeks now and my sweet dog is the love of my life! He is so kind, gentle, and loving. I could not imagine my life without him. Thanks Sergio for bringing such a wonderful companion into my life!

Sergio is absolutely amazing! He answered any and all questions I had about what to do when bringing your puppy home, so I felt very prepared when we picked up our Luigi boy! Gave me a timeline on when final vaccines need to happen, told me what food to buy and how often he needs to eat and he came with a cute little sock monkey with mom and dad scent on it. 10/10 will recommend to anyone whose looking for a sweet schnauzer! Thank you Sergio!!!

Sergio was very responsive. This is our first mini after losing our mini of 11.5 years last year. Sergio answered all questions putting any concerns to rest. It was easy to set up a pick up date and time as well. Being an out of state family with weird schedules it really was seamless with KMS. And our little girl formerly Zoey now Evie Mae is the perfect addition to our family. She is everything Sergio said and more. Sweet, energetic and a major snuggle bug. We couldn’t be happier.

I had an amazing experience with Sergio when adopting my new puppy! He was super helpful, responsive, and clearly knows his stuff. Our pup is healthy, happy, and well-socialized. Sergio made sure we were fully prepared and answered all our questions. Highly recommend him if you’re looking for a new furry friend!
