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.

Story

Meet Hope! Hope’s name says it all—she’s the definition of resilience and new beginnings. Likely a Mastiff/Cane Corso mix, she currently weighs about 60 pounds (and still filling out beautifully). When rescued, Hope was heartbreakingly underweight at just 56 pounds, likely abandoned by a breeder and left to survive on her own. But through it all, her gentle, loving spirit never wavered. Now healthy, happy, and about 3–4 years old, Hope is blossoming into the incredible dog she was always meant to be. She’s a perfect mix of cuddle companion and adventure buddy—content to curl up next to you for a movie night or join you on a walk or hike. She’s playful, affectionate, and has that soulful look that melts your heart. Hope walks beautifully on a leash, adores people, and just wants to be close to her humans. She’s ready for a home where she can continue to thrive, surrounded by love, comfort, and a family who sees how special she truly is. * Fully vetted * Sweet, affectionate, and fun-loving * Loves walks, hikes, and being by your side * Ready to give (and receive!) all the love If you think Hope might be your perfect match, please email adopt@valleydogs.org for more information.

EMERGENCY PLACEMENT DEADLINE5PM MONDAY 09/08/25AVAILABLE FOR ADOPTION ONLY THROUGH PACC Name: MousseAnimal ID: A869969Age: 2 yearsWeight: 88lbs.Web Link: 24petconnect.com/PimaAdoptablePets/Details/PIMA/A869969 About: Just like the delicious dessert he`s named after, our Mousse is a truly sweet guy. This dashing, robust, caramel-colored mixed breed is looking for a hero to give him his second chance at a forever home. Mousse has been through a lot in his young life and recently found himself back at the shelter, but we`re committed to helping him find his perfect fit.Mousse was originally found as a stray and was later adopted. Unfortunately, he was recently returned to the shelter. While we knew he had a history of resource guarding with other dogs, it was discovered in his adoptive home that he also struggles with resource guarding around children. Because of this, it is crucial that his new home has no children.Mousse also needs to be the only pet in the home. He has a history of resource guarding with other dogs, which led to a previous altercation and injury. It is essential that his new family fully understands this behavior and is prepared to take all necessary precautions to keep Mousse and any other household members safe.In his previous home, Mousse was described as a playful and affectionate dog who loved to be by his person`s side. His foster parent shared that Mousse has `so much love to give in the right home.` He`s a big boy with an even bigger heart; just waiting for a family to shower him with affection and provide the dedicated guidance he needs. He is energetic and will need a secure yard and monitoring to ensure he doesn`t attempt another escape.Mousse is a good dog who needs a savvy adopter who understands his unique needs. If you`re looking for a loyal, lifelong companion and believe your home is the perfect fit for Mousse to thrive, please come to PACC and ask to meet this magnificent boy. This is his last chance at finding his forever home, and he deserves a hero of his own.Available adoption Only through PACC.Interested parties:Must visit PACC before the 5:00PM Monday September 8, 2025 deadline to meet with a counselor who will review notes and introduce you to the dog to ensure that it’s a good fit. Some dogs may also require an introduction to any dogs they may potentially live with. Home Management PlanInjured Another Animal • alter
