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 0wks

Story
Coffey is a dog full of love. He operates in a low, slow gear but stays close and engaged. Coffey is a big fan of treats and humans, especially if they come with treats. He appreciates a long, slow walk, but also enjoys a quiet chat sitting in a park. Coffey is interested in his surroundings but is neutral when he meets other dogs or animals. He likes car rides but needs a little boost getting in and settled. We think Coffey will be at his best in a quiet environment with a predictable schedule and plenty of room to stretch out.
