Alvin was so responsive and communicative during the entire process. From the initial questions to when we took our little girl home, he was there and super kind. The fact that he has people travel from all over the country (and out of) for his puppies says something. I asked to come and see the pups and meet our little once before we picked her up. I felt it was important to see the environment that is their home during the first months of life. Needless to say, I was extremely impressed. Alvin and his family are very sweet, not to mention, have a clean, beautiful home and property that the pups can be free to roam and enjoy. Rest assured, they are safe, loved and taken great care of. My husband and I couldn’t be happier and absolutely adore our little Ruby girl. Thank you, Alvin!

From start to finish, Alvin was really great with communication! We appreciated his honesty, informing us of things to look for with our new pup, and was very reasonable in pricing. When we made the drive to their home, they were very kind, informative, organized, giving us many items for the long drive home, with our new bundle of joy! Our new cavalier, Penelope, is 11 weeks and thriving! She is healthy, sassy, and brings a ton of fun into our household! Thank you to Mountain Breeze, for blessing us with a wonderful cavalier!

Alvin was an absolute gem to work with from start to finish. He answered all of our questions and kindly obliged our (what felt like non-stop) requests for new pictures and videos of our pup Rook (formerly Harvey) as we awaited his pickup. Alvin clearly cares deeply for his dogs and when we arrived to pick up Rook we were greeted by his adult cavaliers that seemed happy and healthy as could be. His puppies were all together in a spacious playpen outside where they ran around and were having fun while we met Rook. We were extremely impressed with the level of health testing he does with his dogs, which is of the utmost importance when selecting a Cavalier puppy, and gave us comfort that he is a highly ethical and careful breeder. Could not recommend Alvin and his dogs more, Rook has been an absolute pleasure in our home with our other dog and has made everyone who has met him fall in love.

I had a wonderful experience with Alvin. From the very beginning, he was responsive, knowledgeable, and genuinely cared about his puppies. Mel (Katie) arrived healthy, well-socialized, and clearly raised with love. He was always very attentive and quick to respond to all of my questions — even late at night — which made the entire process feel very reassuring. He also promptly shared videos of Mel, which meant a lot to us and showed his transparency and care. He provided a thoughtful starter kit along with a generous amount of food, which showed how careful and well-prepared he is. We are so happy with our puppy and truly grateful for the experience. I highly recommend him to anyone looking for a responsible and trustworthy breeder.

Alvin was an absolute pleasure to work with. He was super responsive and patient with all of our questions. His prior socialization and handling of Larry (formally Jake) made it such an easy transition into our home. He provided an extensive vet check that our vet said was one of the best documentations she has seen. We are so happy we found him and Alvin set us up for success, without a doubt we would work with him again.

(Fritz) now Goose is the perfect addition to our family. Alvin was a pleasure to chat with and work with to get our little guy home. Alvin is responsive and active on good dog so whenever you have a question he is around to answer! Goose is the perfect addition to our family and we love him so much!
