Story

No one seems to have told Spirit that she's a little to big to be a lapdog! She's prefers affection and snuggles over treats or toys. Spirit is very easy to leash and walks quite well - she could care less about the chattering squirrels in the play yard. She's curious about other dogs but not reactive and just takes a very chilll approach when meeting new people. In her previous home she had free-roam of the household and was very housetrained (we think so too). We love this mature, mellow and gentle girl. Come meet her and see if you feel the same way.November 6, 2026, 7:18 pm

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.

Adoption fees help cover the medical care of the animals while he or she waits for a new home, as well as food and transportation costs. These fees help to provide care for the other animals in the shelter or rescue group who may have medical bills that are much higher than any possible adoption fee. The money also acts as a donation to help support the organization as a whole, allowing the group to continue its efforts to rescue and rehome pets.
