Story
Meet Neko, he is a gentle giant. He has the warmhearted soul with the softest eyes and the biggest potential for love. This handsome boy arrived at our shelter after an injury to his ear which gives him his quirky signature, one floppy ear. Neko is a curious observer of the world—he takes his time, watches with wide-eyed wonder, and once you’ve gained his trust, you will have a new bestie. As a friend you will witness his whole expression soften, he leans in closer and his tail gives a shy little wag. It’s like watching a flower open in slow motion, and it’s impossible not to fall for him. Neko is good in the home to free roam, friendly with other dogs, potty trained, he’s stunning and so-so very sweet — all he needs is the right home and the friendship will flourish. 🐾❤️Paws, love & loyalty 🛋️ Professional lounger 💋 Expert heart-stealer 👑Fetch King 🏡 House-trained Neko thrives with individuals who understand that trust is built, not rushed (a slow dance, not a race). If you have patience and a calm demeanor, Neko might just be the enchanted companion you’ve been dreaming of!

Story
Ready to float away from the hectic kennel life like a grand airship ascending into a clear sky, Zeppelin is a gentle soul searching for a soft runway to land on. He sports a truly beautiful brindle coat with an intricate pattern of rich dark brown and black tiger stripes that instantly catches the eye. With his hazel eyes and relaxed expression, he often looks like he is wearing a soft, contented smile when he connects with a friendly face. Currently a bit on the slender side, he is looking forward to finding a comfortable routine where he can build up his strength and gain some healthy weight. This sweet fellow moves at a thoroughly chill pace and has an easy, loose leash walk when heading outside. Though he can show a slightly shy side when first introduced to unfamiliar situations, it only takes a quiet minute of patience before his true, loving nature lifts off. Once he feels secure, he will happily step closer to be right by your side, leaning his body in to soak up gentle pets and scratches. He shows a wonderful appreciation for toys and handles tasty treats with a polite, easygoing manner. A serene home environment is exactly what this friendly boy needs to feel completely safe and allow his sweet personality to fully expand. Providing a peaceful space away from the loud shelter noises will give him the perfect opportunity to relax, receive the steady affection he craves, and truly flourish. You can lift Zeppelin out of the busy shelter environment and into a comfortable life by reaching out to meet him today.

Meet Bubba Gump! 🐾 If you are looking for a loyal, big-hearted companion with a personality that completely fills a room, Bubba Gump is your man! This handsome, fawn-colored Mastiff mix is the ultimate "gentle giant". He is a sweet old soul who thrives on a predictable routine and is happiest whenever he is right by your side. Whether he is lounging around like an angel or wiggling across the floor in his own uniquely goofy way, Bubba makes himself at home in any heart. Bubba enjoys the absolute best of both worlds. He is always enthusiastic about his daily walks - especially if he gets to shake down bushes to look for lizards - but he is equally content to just chill out and nap at home when you are around. He is highly trainable, incredibly food-motivated, and already knows basic commands like sit and stay. He has also made fantastic progress on his loose-leash training, making him a wonderful walking partner! To help this unique guy put his best paw forward, his ideal forever home looks like this: 🏡 A Mature, Relaxing Environment Bubba is a distinguished gentleman who prefers a peaceful home with adults or older teens where he can truly unwind. 👑 The Star of the Show He would thrive as your one-and-only pup , but he can also comfortably coexist with a confident feline friend. 📅 A Predictable Routine Because he loves his people so much , he does best with a consistent schedule. He loves mental enrichment toys to keep his clever mind occupied when you're away from home. 🤝 A Dedicated Inner Circle Because he takes his role as a loyal companion seriously , he prefers quiet, controlled outdoor introductions for new visitors , and he is easily won over with a slow approach and a tasty treat! Bubba Gump is so much more than just a pet - he is a devoted friend, a hilarious character, and a companion who is ready to give you a life filled with love. If you have room in your heart for a quirky, loving giant, click the inquiry button to see his floor wiggles in action!

Story
Cleo is a beautiful, sweet, healthy 10-month old Mastiff mix who is a loyal companion and playful friend. She is young enough to easily acclimate to a new home and owner. She knows basic commands and is crate trained and house trained. Cleo loves to go on walks, play tug of war, and chase (but never harm) lizards. She is a strong and healthy girl. When playing, she sometimes nips, but she stops when corrected. She responds to "sit," lay down," "walk," "food," "no bite," and "lizards."Cleo loves to be around other dogs. With humans, she can be shy at first and needs slow introductions. Once she gets familiar with someone, though, she is eager to greet. She is best suited in a home without young kids due to her quick-to-startle nature. She does well with two walks a day (morning and evening). Having a backyard is great for her so she can roam and get some young dog energy out. She is pretty calm and naps during the day.Cleo would benefit from an experienced dog owner who will enjoy helping her grow and appreciate her playful and protective nature.Potty trained: yesCrate trained: yesCar rides: she enjoys themBaths: she likes a bathGood with dogs: yes - very excited to meet and play with dogsGood with cats: untestedGood with kids: best suited in a home without kidsHealth: good.Vaccines: she is up to date on vaccinesHeart worm: she is negative for heart wormBehavior: she can be hesitant around new people and situations.

Story
Meet Jelly Donut, a charismatic, goofy 130-pound gentle giant who genuinely believes he fits perfectly in your lap! This fun-loving gentleman is as bright and observant as he is hilarious. His signature move? Conning you into a game of fetch—he’ll happily watch you throw the ball, fake a run, and then sit back to watch you go retrieve it. Jelly Donut brings pure joy wherever he goes, whether he’s doing enthusiastic backyard zoomies, relaxing on a sunny brewery patio, or embarking on epic "sniff-safaris" on leisurely neighborhood walks. When he gets super excited to play and engage, his inner puppy comes out with a few happy hops, but at his core, he’s a massive cuddle bug who just wants to soak up all the pets you can offer. He’s a big fan of squeaky toys, Kongs, cheese, people-watching, and taking long, glorious naps after a good enrichment session. Research shows that giant-breed dogs bring unmatched companionship and grounding energy to a household. If you’re looking for a larger-than-life character to make you laugh every single day, come meet Jelly Donut—he’s ready to steal your heart (and your spot on the couch)!
