Story
Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.

Story
Hazel is a loveable loaf in search of a comfy couch to snuggle on! She`s sure to charm you with her adorable personality and stunning brindle coat. Hazel isn`t a fan of sharing her yummy bones with other animals, so she is required to be the only animal in her next home so she can be spoiled rotten with snacks and affection! At this time, HSBV is also requiring a home either without children or with children over the age of 10.
