Story
NOTE:Submit the adoption interest application directly at our HSNB website:https://www.hsnb.org/dog-adoption-applicationWe may not receive anything submitted through PetFinder or Adopt-A-Pet! If you do not receive confirmation from us, email adoptions@hsnb.org . -----Meet Nami, a beautiful Mastiff/Rhodesian Ridgeback mix with a heart of gold. When she first arrived at our shelter, Nami was a bit shy, taking her time to observe her new surroundings and the people around her. Once she got the hang of things, her true, affectionate personality became very apparent.Now, Nami has truly blossomed into a wonderful companion who clearly adores people. She enjoys a relaxed pace on her leash walks, taking everything in with a quiet demeanor, and is even open to making new dog friends. More than anything, Nami longs for a place where she can feel safe, secure, and cherished. She dreams of a loving home where she can offer endless affection and receive it in return. Nami's adoption fee is $350.https://youtube.com/shorts/tCoPkwAgl2M Primary Color: Brown Secondary Color: Brindle Weight: 82.5 Age: 2yrs 9mths 4wks

Story
This friendly, easygoing guy has a calm, independent charm. He enjoys exploring the world at his own pace, especially when there are good smells to investigate, and is happy to share affection when he’s in the mood. He’s polite and neutral around other dogs and would do well with a family who appreciates a more laid-back companion that values both adventure and quiet independence.
