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 3wks

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.

Story
Pine is our sweet, gentle giant, brindle mastiff and he is wonderful. Very easy to walk on leash, non-reactive. He loves treats and takes them daintily.Seems potty trained.He enjoys relaxing on the grass to watch cars go by.He has the most soulful expression; we see it as his inverted happy face :)He's dreaming of that special person. Someone to make him smile. Rated 12 out of 10 as a very good boy!To make an appointment to make Pine smile, please go to yoloshelter.org/adopt. All animals are up-to-date on vaccinations (including rabies if over 4 months old), microchipped, and spayed or neutered. All dogs have been been vaccinated with DHPP and Bordatella (kennel cough) and heartworm tested negative (if over 6 months).    All cats have been vaccinated with FVRCP and current on flea control.
