I'm David C., the breeder behind David's Mastiffs located in Illinois. We are lifelong dog enthusiasts, and we’re excited to share our passion and purpose with others through our breeding program. We are a small enough program that we are able to thoroughly focus on each individual dog and puppy and their needs. We take pride in the time and dedication we give to every litter.
David has been certified by Good Dog’s screening team for responsible and trusted breeding practices. When you’re ready to reach out, feel free to ask any questions about the breed, their program, or specific puppies.
Together, you’ll choose the puppy that’s right for you, stay in touch with regular updates, and plan how to bring your new puppy home.

David 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 David 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 David directly.
