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
Minnie is estimated to be a 2yr old Pittie/Lab mix. We are so grateful that thanks to our fosters & supporters, we were able to pull her on her euthanization day and give her a chance at the good life! She will be settling in with a foster until we find her a forever home. We want this girl to land somewhere permanent ASAP so she can build trust with humans and let her true self shine through. If you are interested, apply today and let's get her happy journey started. Look at this sweetheart, she deserves it! A little about Minnie: She is a shy girl who needs a patient owner to help her adjust and feel safe as she transitions to the good life. At the shelter, she was too scared to even come out of her kennel for a walk. Upon rescue she wan gentle, friendly, and understood some commands. We even got belly up for rubs when we were loving on her! Treats were very exciting and we took them with grace & enthusiasm. This girl is going to make a gentle & loyal companion for someone - could it be you?? Apply today! We believe her needs to be: * Time to decompress, relax and feel comfortable with someone * To be with someone who will respect her shyness & have patience as she learns she doesn't have to be so scared of the world * She need someone to take their time with her and convince her they aren't going to hurt her *Best as an only dog or with a comforting dog that will help her come out of her shell

Story
Geralt is a goofy, adorable guy who doesnâ&#194&#128&#194&#153t quite realize how big he is. He can be cautious with new people and needs a little time to settle into new environments, but once he feels comfortable, his playful personality shines. Geralt walks well on leash and is looking for a home without small kids where he can relax and feel secure.November 16, 2025, 12:27 pm
