Story
KLAEBO | 4 Months | 30 lbs | Dark Chocolate Brindle Mastiff | Male This sweet, bumbly boy is still just a baby — 4 months old and already 30 pounds of gentle love. Klaebo is friendly, slightly shy at first, and incredibly kind. He plays beautifully with other dogs and is curious about cats (but gentle!). He rides great in the car and would happily grow into the ultimate big family dog. Klaebo was seen being dumped from a car and left behind on Putah Creek Road. A good Samaritan couple immediately scooped him up, trying to get a license plate number but sadly couldn’t. No puppy deserves that kind of beginning. Now, this future gentle giant is looking for a committed home — ideally a stay-at-home or large, active family who understands the needs of a Mastiff as he grows. He will be BIG, loyal, and deeply bonded to his people. Let’s help this boy win GOLD with a family of his own — whether that’s 1, 2… or 6 people cheering him on. $350 adoption donation Includes neuter vaccinations and chip Adoption form here to get started heartsforpawsrescue.com/adoption-application Follow facebook.com/heartsforpawsrescue & Instagram @heartsforpawsrescue for more!

Story
Pine is a gentle, sensitive boy who bonds closely with his people and truly shines once he feels safe and comfortable. He enjoys treats (which he takes very politely) and is happiest during calm, low-stress moments like lounging on the grass, soaking up attention, and simply being near his humans. Pine is reactive toward other dogs and bikes. Because of his size and strength, he will require a confident, experienced handler who understands leash management, training, and how to work with a powerful dog. Children are also new for Pine. During a recent adoption event he had the opportunity to meet children but was a little uncertain around the tiny humans (not aggressive, just a little confused). He may be able to live with calm, dog-savvy kids given proper handling and thoughtful introductions, but a predictable environment will be important for his success. Pine is a classic gentle giant in many ways: sensitive, loyal, and deeply people-oriented. He needs the right home to help him feel secure and navigate the world more comfortably. Schedule an appointment to meet Pine at yoloshelter.org/dogs or email adopt@yoloshelter.org February 24, 2026, 3:24 am
