If you do not receive the automated confirmation from us, email adoptions@hsnb.org -----Olaf - A Loyal Companion with a Big Heart 🤍🐾If you appreciate the depth and devotion of a large breed dog, Olaf might be your perfect match. This handsome 3½-year-old grey Mastiff weighs about 95 pounds and is looking for an experienced handler who understands and respects the unique needs of a powerful breed.When Olaf is in his comfort zone, his steady and affectionate nature truly shines. Staff have been incredibly impressed with his beautiful leash manners-he walks nicely and calmly, making outdoor time a pleasure. He is a loyal, sweet companion who thrives on routine and enjoys relaxing right by your side.Because of his size and protective instincts, Olaf requires an adult-only home with no children or cats. He is looking for a savvy, large-breed-experienced adopter who can provide consistent structure and leadership. Olaf has shown some selective reactivity in his foster home, particularly around men, and will need a patient, structured decompression period. An ideal home would be one with a confident, primary female handler or a household experienced in managing breed-specific boundary setting.With the right guidance and a dedicated owner who understands his signals, Olaf has the potential to be an incredibly devoted partner. He is big in size, deep in loyalty, and ready to find the structured, loving home he deserves. 🐶Adoption fee: $300 Primary Color: Grey Weight: 95 Age: 4yrs 0mths 1wks

Story
Meet Leo – A Loyal, Intelligent Dog Looking for the Right EnvironmentLeo is a loyal, intelligent dog who bonds deeply with his people and thrives in a calm, structured environment. He is highly trainable, eager to please, and enjoys working with his handlers.Adopted in 2022, Leo has a history of trauma that can make him fearful and reactive. We’ve worked extensively with trainers and the SF SPCA Behavior Program, and he has made meaningful progress. He gets along well with other dogs and has strong obedience skills.Leo does have a bite history and needs an experienced, adult-only home. His fear can escalate quickly, so he requires someone comfortable managing reactive behavior. He is muzzle-trained and does well with structure.We love Leo deeply and are committed to finding him a safe, understanding home where he can truly thrive. Behavioral records available.Rehoming fee applies to ensure a serious, committed placement—may be waived for the right home.
