Story
Adam is a 65-pound calm and cuddly boy who is doing well with his amazing foster. He now walks on a leash and is eager to "sit" for his dinner. He gets along great with female dogs and is not overly curious about cats. He is a protective boy over his family and property, but when given proper introductions, he is the most loyal and gentle guy you'll ever meet. He needs an adopter who can guide him with boundaries and offer lots of socialization opportunities.

Story
Breathless Mahoney is a gorgeous ~2 year-old mastiff mix. Mahoney currently weighs 90 lbs, but needs to gain some weight and will probably fill in at around 100-120 lbs. Breathless Mahoney is a little shy with new people but once she warms up, she loves to play and snuggle. She is very playful with other dogs and has a puppy-like rough-and-tumble play style.

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

Story
Cookie is a sweet, cuddle-loving, gentle, smart and happy young dog. She loves to play with kids, does great around the chickens and other animals. Follows commands such as sit, come, stay, wait. She loves to swim and enjoys walks very much. She is leash trained as well. She was part of a surprise litter of pups to a mother who is half cane corse and Australian shepherd mix and father full cane corso. She is in need of a new home due to landlord request of exceeding animals in the home. She is very loved and will be missed greatly. I am hopeful she will find a home where she will be given the love and attention that she had with me...even more.
