I'm Adrianna F., the breeder behind Yamainu located in Twin Bridges, MT. Located in the high mountains of Southwest Montana, we are a small batch, purpose driven breeder dedicated to producing dogs based on champion conformation with the athleticism to show up and perform in sport and competition, with the added grit needed when facing the realities of the backcountry or navigating the hustle and bustle of the city. Big skies, fresh air, and the mountains in our back yard provides us with the perfect environment to grow strong, stable, healthy pups. Bonding closely with their family, we are as dedicated and loyal to our dogs as they are to us. We pride ourselves on our well focused eye for promoting health and genetic diversity for this rare breed, importing for type and temperament as well diversity as we move into the future of the Japanese Akitainu in the United States. That being said, finding appropriate, dedicated pet and breeding homes is of utmost importance to us here at Yamainu. Please do not hesitate to reach out to us, we love talking about our dogs!
