The process was easy. The breeder, Sergio, was responsive and professional. The puppy is acclimating with the rest of my dogs and she’s growing rapidly.

Sergio was great with communication and very responsive. You can tell that he’s knowledgeable about the breed and truly cares about the puppies’s well-being. Meeting up with Sergio was also easy. We love our precious baby girl Sunny and knowing she came from a family that loved and will continue to love her by making the best choices for her- makes me feel confident in Sergio. We will definitely be reaching out to Sergio again in the future when we’re ready to expand our schnauzer family!
