After buyers complete the application and screening process, Deandre partners with them to find the best puppy match.
“Our puppies are placed based on temperament, structure, and suitability—not on a first-come, first-served basis. We carefully evaluate each puppy’s personality and energy level, then match them with the home that best fits their lifestyle, experience, and expectations. While preferences (such as gender or color) are considered, the final placement decision is made to ensure the best long-term outcome for both the puppy and the owner.”

Deandre 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 Deandre 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 Deandre directly.

About Nala
well-built Tibetan Mastiff dam with a rich golden coat and strong, balanced structure. She carries herself with quiet confidence, embodying the natural dignity and instinctive awareness the breed is known for.

She doesn’t overreact; instead, she shows measured judgment and steady composure, making her both dependable and level-headed. With her family and trusted people, she reveals a softer side. She is affectionate, calm, and deeply loyal, forming strong bonds and showing a nurturing temperament that translates well into her role as a dam. Her maternal instincts are evident, patient, attentive, and protective of her litter.

About Knuckles
Knuckles is a commanding 160-pound Tibetan Mastiff male with the kind of presence that turns heads and quietly establishes authority. Bred from champion lines, he embodies the strength, structure, and temperament expected of a true guardian sire. He carries himself with calm confidence,never reactive, never uncertain. His natural guarding instincts are sharp and reliable, and when he’s working, he’s focused, territorial, and unwavering. He doesn’t bluff; he assesses, decides, and acts with purpose. Outside of his guarding role, Knuckles shows a completely different side. With family and trusted people, he’s exceptionally affectionate, welcoming, and steady. He has that rare balance of being both a formidable protector and a genuinely loving companion. Socially, he’s well-adjusted and composed. He works well with other dogs, showing neither unnecessary dominance nor insecurity. His temperament reflects stability, intelligence, and control
