Please note this dog is NOT an official Underdog dog, and you will be connected with the person who has the dog. Please Contact (Current Owner of Dog): Brittany Schultz; 510-458-4151; animal.shelter@sierravistaaz.gov MEET MAGNUM!! Magnum is a friendly, goofy, and even-tempered male dog who has been patiently waiting at the Sierra Vista Animal Shelter for over 340 days and is more than ready for a fresh start. He walks well on leash, enjoys car rides, and loves toys, bringing a playful spark and charm wherever he goes. Magnum does best with adults and would thrive in a calm, experienced home where he can soak up attention and structure. While he can tolerate other dogs, he would be happiest as the only pet, but any potential canine siblings should be introduced through a proper meet and greet. His history shows he does best in a stable environment, and with the right person, Magnum will be a loyal, fun-loving companion who’s eager to finally have a place to call home.

Please Contact (Current Owner of Dog): Charlene Garst; 480-2924576; grammag05@gmail.com MEET DAISY #27!! Daisy is a sweet, affectionate, and intelligent pup who forms deep bonds with her people and thrives in a calm, structured home where she can be the only pet. She is leash and crate trained, obedient, eager to please, and loves toys, fetch, and interactive play, but her favorite thing is simply being close to her humans. Daisy does wonderfully with respectful children and all adults, especially when interactions are gentle and consistent. She enjoys a predictable daily routine, relaxing walks without distractions, and car rides, and she settles nicely when given time to adjust to her environment. While she can become anxious around other dogs or during transitions like departures, she responds well to reassurance, soothing touch, and clear guidance, and she has training tools in place to help her succeed. Daisy would flourish in a patient, loving home that can provide structure, stability, and plenty of affection, where she can truly shine as a devoted and loyal companion.

Story

Leah is a stunning 90 lb Mastador (75% English Mastiff / 25% Lab) who perfectly captures the best of both worlds. At her core, she is a world-class lounger. If there is a TV on and a spot on the rug, Leah is happy to be your companion for a movie marathon. But don't let the Mastiff side fool you—the Labrador in her comes out the second she sees a pool! Leah is a rare big girl who loves to swim and play in the water. She is wonderful with children and other dogs, making her a great fit for a busy home. Leah does have a sensitive soul. She thrives on companionship and can get anxious and a bit 'mischievous' if left alone . She’s looking for a family where someone is home more often than not. Because she values her meals highly (food aggressive), she needs a home that understands how to give her a quiet, safe space to eat away from other pets. If you’re looking for a giant sweetheart who will watch your favorite shows with you and join you for a summer swim, Leah is your girl
