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.

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

Penny came to us from the euthanasia list at the county shelter. She weighed a severely overweight 110 lbs and suffered from chronic eye issues. She was going to be euthanized for her medical needs. She was a volunteer favorite at the shelter, and what was more than clear to all of us was that this precious girl had simply never been given the chance to live the life she deserved. Since coming into our care, Penny has lost over 45 lbs and is looking better than we could have ever imagined. She has transformed into the type of dog who would fill her perfect home with all the love in the world. She loooves to play, adores her toys, has learned impressive obedience commands [and impulse control!], and she really is something special. Given her size and strength, Penny would do best with a person or family who can keep up her obedience work at home so she can continue to be her very best self and get in all the walks and activity that she needs. And speaking of home, she would love to be your one and only fur baby, and she made me promise to tell you that a yard for her would be a dream come true. Penny's adoption fee includes her completed veterinary exams, bloodwork, vaccines, microchip and spay. With her in it, we can promise your home won't feel empty again, and she is sure to steal your heart 100 times over...guaranteed! To meet Penny, apply here https://lovethemallrescue.org/penny. She is sure to steal your heart 100 times over.
