Story
Namora is a friendly, energetic puppy who's super smart and eager to please. She loves cheese, exercise and attention. She knows some basic commands and enjoys treats... a lot. We have little background info on Namora; largely for that reason, we recommend older kids in her new home (10 yrs and up). This gem of a pup needs an active owner to help her burn off some of her puppy energy.May 31, 2026, 3:11 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.

Size
(when grown) Large 61-100 lbs (28-45 kg)
Details
Good with kids, Not good with dogs, Good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Fang is a gentle old soul. His favorite things to do are sun bathing, snuggling, and napping. He loves chasing squirrels in the yard and ripping up his stuffy toys. He is free roam in the house and 100% potty trained. He knows sit, stay, leave it, here, lay down, bed, upstairs and downstairs. He'll be turning 9 in August. He is the most intelligent and sweetest dog we've ever had. He's never ripped up anything in the house, never gone into the trash, or even drank out of the toilet bowl. My husband and I love him however we are heavily sleep deprived. We welcomed a beautiful baby girl into the world a year ago and don't have time for Fang. It's not fair to us or him. We don't want to take him to a shelter. We would love if he went to someone who is looking for a chill companion in his senior years of life. If you want a cuddle buddy and a chill shadow, Fang would be a wonderful addition to your home. He deserves care, attention and love.

Story
Meet Fang, a Mastiff mix with a heart of gold and the most intuitive soul you’ll ever encounter. Fang is the ultimate "gentle giant" who has reached his glory days and is looking for a couch to call his own. Fang is incredibly smart and acts as a loyal alert dog for the home. He is trained off and on lease and is naturally defensive of women. While he sounds intimidating to a stranger, he’s actually a total "scaredy-cat" who just wants to feel safe and loved. He surprisingly loves cats and enjoys a good game of tug-of-war. As he’s gotten older, his back legs get tired a bit faster, so he prefers short, leisurely strolls over long hikes. He’s a professional lounger who will happily nap on the sofa all day. He has been lovingly spoiled! His favorites include chicken and any kind of cheese. We’ve recently welcomed a new baby into our family, and we’ve realized we can no longer give Fang the focused attention and environment he deserves.
