Story

You can fill out an adoption application online on our official website.Meet Miles! Miles is a 17-week-old Mastiff mix with the perfect combination of puppy curiosity and gentle giant energy. Even at a young age, he’s already showing the loyal, affectionate personality Mastiffs are known for. This sweet boy loves being around people and is happiest when he’s close to his humans, whether that’s playing with toys, exploring the yard, or curling up for a nap after a busy puppy day. Miles is still learning about the world and will thrive with a family committed to continuing his training, socialization, and puppy basics. Like most Mastiff mixes, Miles will likely grow into a large, loyal companion, so he’ll do best with adopters who are prepared for a big dog and the love (and drool!) that comes with it. At just 17 weeks old, Miles has his whole life ahead of him and is ready to find a family that will help him grow into the amazing dog he’s meant to be. If you’re looking for a loyal best friend to grow up with your family, Miles might just be your perfect match. &#226&#157&#164&#239&#184&#143 AZ Mastiff Rescue Phoenix, Arizona Fill out an application at: www.azmastiffrescue.com Our adoption coordinator will be in touch ASAP #azmastiffrescue #pacc911partner #rescuedismyfavoritebreed #adoptdontshop #mastiff #englishmastiff #canecorso #giantbreed #dougedebordeaux #droolhappens #phoenixarizonaVisit this organization's web site to see any additional information available about this pet.March 11, 2026, 2:44 am

Story

You can fill out an adoption application online on our official website.Meet Rob Thomas — a sweet, big lug of a dog who is basically a furry giant marshmallow. At about 1 yr old, Rob is house-trained and crate-trained and has wonderful manners in the home. Rob previously lived in a foster home with several other dogs and truly enjoys canine companionship, so his ideal home would include one or two other dogs to keep him company. Like many giant breeds, he thrives with structure, space, and people who understand and appreciate these gentle giants. He’s a lovable, easygoing boy with a big heart, and someone out there is going to get an absolute gem of a dog. Rob would do best in a home with children over the age of five simply due to his size and enthusiasm for life. If you’re looking for a loyal companion with a marshmallow personality, Rob Thomas might just be your guy.

Story

You can fill out an adoption application online on our official website. Joyce waited for someone who never came… Joyce is a 2-year-old Mastiff who found herself scared and confused in the Lancaster shelter. When we first reached out to pull her, we were told she already had an adopter waiting. We were relieved… we thought her story was about to have a happy ending. But the adopter never came back. After Joyce was spayed, she sat and waited. And waited. Days passed. No one returned for her. A week later we saw her name appear on the E-List. By then she was sick, depressed, and completely shut down. We dropped everything and rushed to the shelter. Twenty minutes later Joyce was walking out the door with us. Now that she’s safe, the real Joyce is starting to show. Beneath the fear is a very sweet, gentle, submissive girl who just wants to feel safe again. She is dog friendly, appears to be house trained, and has been very respectful in the home. Right now Joyce is learning that people won’t leave her behind again. She’s slowly gaining confidence every day. What she needs most now is a patient, loving home that will give her the time and reassurance she deserves. Because the first person who promised her a home didn’t show up… But the right one still can.
