Story
🐾🖤 MEET RILEY — A BIG HEART THAT DESERVES TO BE SEEN 🖤🐾 This is Riley — a 3½-year-old Mastiff mix weighing in at about 86 pounds of pure love. And while we can’t say for sure why he’s still waiting, we can’t help but wonder if Riley is being overlooked because of something called Black Dog Syndrome — the unfortunate reality that black-coated dogs often wait longer for adoption simply because they’re harder to photograph or don’t “stand out” at first glance. But spend five minutes with Riley, and everything changes. 🖤✨ Riley is a giant teddy bear, rescued from the Costa Mesa Animal Shelter, with the gentlest soul and the sweetest personality. He’s house trained, great on leash, and a total social butterfly who lives for his daily walks and being close to his people. Whether it’s cuddle time or stroll time, Riley is just happy to be by your side. 💬 What our volunteers say: “This big, beautiful guy is now my #1 favorite.” “My latest kennel crush — 80+ lbs of sweetness.” Riley doesn’t need flash or fanfare. He just needs someone to see past his dark coat and notice the golden heart underneath. He’s loyal, affectionate, calm, and ready to be someone’s best friend. If you’re looking for a steady, loving companion who will fill your home (and couch) with warmth — Riley is your guy. And even if you’re not his forever person, please share Riley’s story. You never know who might be looking for exactly a dog like him. 🐾🖤 Let’s make sure Riley isn’t overlooked any longer. 💛🐶

Story
Hi all! I’m Brody! I’m 4 years old and have been told I’m a total meat head who isn’t always aware just how big he is. I hear everyone calling me a handsome beefcake, which I can only imagine is a good thing. ☺️So far, everyone thinks I’m a mastiff/pit bull mix, hence the beefcake comments, but we’re not 100% sure as we haven’t done a DNA test. Regardless of my breed, I know I’m 100% handsome, because my foster mama tells me every day! 😍 I’ve got a big ole head, and a giant heart to match. 🫶 Not only am I easy on the eyes, but I’m also fully trained! I’ve got my basic obedience down, walk great on a leash and am crate trained. I love ALL dogs, even the littles, and my motto is #BALLISLIFE! I could play ball EVERY DAY and would love a home with a family who will play with me! But not to worry! I’m also perfectly content with some R&R at home and can be a lazy potato. My ideal home would be with a family who is patient and kind. I’ve had a lot happen to me in my 4 years on this earth, so I can be nervous meeting new people. However, I can also warm up really fast, and once you’re in, you’re in forever and we’ll be the bestest friends forever! 👯🤗 I’d also do best in a home with strong leaders, because let’s face it… I don’t like having to make choices. I mean, can ya blame me? Making decisions is a tiring thing, and why spend time doing that when I could be having fun! I’m fully vetted, neutered, current on all vaccines, microchipped and looking for my forever family.
