Greg 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.
Greg 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.
“We use breeder-directed placement to ensure every puppy goes to the home where they will truly thrive. Because we live with these puppies from day one, we get to know their individual energy levels, drives, and developing personalities inside and out. Giant Schnauzers are a versatile breed, but a puppy that is perfect for an active farm environment might not be the best fit for a quieter suburban home, and vice versa. Instead of a "first-come, first-served" pick, I work closely with each of our families to understand your lifestyle, goals, and home dynamic. Using that information, I will help match you with the specific puppy best suited to your needs. Our ultimate goal is a perfect match, a puppy that fits seamlessly into your life and a family that can give that specific puppy exactly what they need for a happy, successful future.”

“Deposits are non-refundable. Reserving a puppy means turning other wonderful families away. Your deposit secures your spot and directly supports the care and health of our breeding program.”
Greg 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 Greg 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 Greg 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 Greg.

Vanguard Giants meets or exceeds our community standards in these areas:
Giant Schnauzer
About Rhea
Rhea is the heart of our home and an incredible mother. True to the Giant Schnauzer breed, she is exceptionally intelligent, highly observant, and deeply devoted to her family. On our farm, she strikes the perfect balance between an alert protector and a gentle, patient companion who loves being around the kids. Her calm, stable temperament and maternal instincts pass beautifully down to her puppies, making her an invaluable foundation for our program.
Great health testing
Giant Schnauzer
About Cerberus
Cerberus is the definition of a loyal companion and a total working dog at heart. He thrives on having a job to do and loves nothing more than putting his nose to work. Whether we are practicing scent exercises or just exploring the farm, his focus and scent awareness are incredible. Above all, Cerberus is just a good, eager-to-please boy who loves his family and brings the perfect balance of drive, intelligence, and stable temperament to our program.
Great health testing
Great level
Vanguard Giants reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Giant Schnauzers.
Hip Dysplasia
Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.
Vet Wellness Exam
A breeder may perform additional tests on their dogs that do not fall into these general categories. These tests may be more uncommon or very specific to a particular breed.
DNA Disease Panel
Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
