Story
This big boy is super playful and goofy! He was found dumped in an apartment complex for about four days before we brought him home to get him out of the heat. He has had so much fun playing with my toddlers outside in the water! He gives off a very young vibe, even though he is such a big dog. He has gotten used to being around our cat but not our other dogs yet. We would love to keep this goofball but cannot, he deserves more than just a kennel! Please help us!

Story
“Hi, I’m Porkchop… and I’m Ready for My Real Forever Family.” From the heart of Porkchop himself Hi there. My name is Porkchop, and yes—I know it’s a funny name. Everyone laughs when they hear it, and honestly, I kind of like that. I’m an 8‑month‑old mastiff mix, which means I’m a big boy with an even bigger heart. I didn’t have the easiest start in life, but I’m hoping the next part of my story is the one where I finally find the family who sees me as perfect just the way I am. I was rescued when I was about four months old, standing on the side of the road with my brother. Someone was giving away puppies like we were old furniture, and one of the volunteers from Central Arizona Animal Rescue saw us and knew we needed help. I had never been to a vet, never had any puppy shots, never had anyone making sure I was safe. But that changed fast. They scooped us up, brought us in, and gave us everything we needed—vaccinations, a microchip, and eventually I was neutered. For the first time, I felt like someone cared about me. After a little while, I got adopted. I thought that was it—I thought I had found my forever home. But after a couple of months, they brought me back. They said I was “too big.” I didn’t understand. I didn’t do anything wrong. I just grew, the way puppies do. I tried to be good, but nobody taught me how. They didn’t work with me on leash manners, so yes… I pull when I walk. And sometimes I get excited and jump up because I want attention so badly. I’m not trying to be naughty—I just didn’t have anyone showing me the rules. So here I am again, waiting. Hoping. I’m still the same sweet boy I was the day I left, just a little older and a lot more ready to learn. I need someone who will set boundaries, teach me gently, and help me understand how to be a polite, well‑mannered dog. I’m smart, I’m eager, and I really do want to make you proud. I just need a person who won’t give up on me. My previous owners said I am house trained, which is a pretty great start. And I’m good with other dogs, too. I like having friends. I like being part of a group. I like feeling like I belong. I’m a big, strong puppy, but inside I’m just a soft, goofy boy who wants to be loved. I adore people. I lean in for pets, I wag my whole body, and I melt when someone scratches behind my ears. I’m happiest when I’m close to someone who cares. If you’re looking for a dog who will grow into a loyal, loving companion… someone who will follow you around, keep you company, and make you laugh with his silly mastiff expressions… I might be your guy. I’m still learning, but I promise I’m worth the effort. I’ll give you everything I have—my trust, my affection, my big goofy smile—if you give me a chance. If you’d like to meet me, the rescue says you can email mike@caaronline.org to set up an appointment. I’ll be waiting, hoping the next person who comes to see me is the one who finally says, “Porkchop, you’re home.” Love, Porkchop   PLEASE e-mail (do not call) mike@caaronline.org for more information and to set up an appointment to adopt. Do not e-mail us with a request to call you, if you have a question, please ask in the e-mail.   All dogs are adopted on a first come - first served basis.

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.
