Concord, CA
Size

Story
Nova is a cuddle bug who lives for her favorite person. She’s housetrained, walks great on leash, and is friendly with other dogs. Treats and squeaky toys are the way to her heart, and once she trusts you, she’ll want to be by your side constantly. Nova can get anxious when left alone at first, but she’s shown she can settle down and handle it once she adjusts. She knows “sit” and is still warming up to strangers, so a little patience goes a long way with her. Nova’s ideal home: A backyard, daily walks, and people who want a loyal companion by their side. She does fine as an only dog or with other dogs. Because she jumps when excited, she’s better suited for a home without young kids who could easily be knocked over.   ##2665648##

Story
Adam is an 80-pound silly, calm and cuddly boy doing so well with his amazing\ foster who says her favorite qualities are his squishy, loveable face, his soft fur, and his smile. Adam walks well on leash and is eager to "sit" for his dinner. He gets along great with other dogs. He is calm, playful and has good manners and is not overly curious about cats. He is low energy but really enjoys going for walks and being let out to run and explore in a fenced area. Adam is protective of his family and property and, with proper introductions, is the most loyal and gentle guy! He needs an adopter who can guide him with boundaries and offer lots of socialization opportunities. Everyone who meets Adam falls in love with him! He's just waiting for the right one who's ready to provide him a stable and loving home. If that's you, please submit an application and a volunteer will be in touch! (HD)

Story
Meet our sweet boy Apollo 🐾 Apollo just turned 2 years old on January 5, 2026. He is a loving, affectionate pup who adores belly rubs and enjoys spending time with his people. Apollo is well-mannered and knows basic commands such as sit, stay, lay down, and shake paws. We are heartbroken to say that we are looking for a new family for Apollo due to circumstances beyond our control—our landlord has required that we rehome him. This decision has not been easy, and our only wish is to find a home that will love and care for him just as much as we do. If you are willing to give Apollo a chance and provide him with a safe, loving forever home, please reach out. He truly deserves a family who will cherish him.
