Story
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
Meet Bruno 🐾 Bruno is a handsome ~2-year-old brindle boy with a gentle soul and a heart that just needs a little time to shine. At first, he can be a bit shy and timid, but once he warms up, you’ll see his sweet and loyal personality come through. He does well with most other dogs and would likely enjoy a home with a calm, friendly companion to help build his confidence. Bruno would thrive in a patient, loving home where he can take things at his own pace and feel safe. He’s the kind of dog that forms a deep bond with his people—quiet, observant, and incredibly loving once he trusts you. With a little reassurance and consistency, Bruno is going to blossom into an amazing companion. If you’re looking for a loyal best friend and are willing to give him the time he deserves, Bruno might just be your perfect match ❤️ Please email ADOPT@VALLEYDOGS.ORG for an adoption application. Thank you!

Story
Meet Hank! This impressive and devoted Boerboel — a striking, 5-year-old neutered male with a heart as big as his presence. Confident, intelligent, and deeply loyal, he embodies the true spirit of a guardian breed and flourishes in a home that understands and appreciates his protective nature. He would do best in an adult-only home (no kids), as he plays rough and doesn’t always realize his own strength. This boy loves to explore and would be happiest on a property with space, where he can spend most of his time outdoors doing what he loves—patrolling, roaming, and taking in his surroundings. While he enjoys his independence, he also appreciates human interaction on his terms. He may take a little time to warm up, but once he trusts you, he’s a solid, loyal companion. Ideal Home: Adult-only household Experienced, confident dog owner Property or large yard preferred Someone who understands guardian breeds He’s a great dog in the right setting—strong, smart, and full of character. With the right person, he’ll be an incredibly rewarding companion. Please email ADOPT@VALLEYDOGS.ORG for an adoption application.
