Story

Meet Oswald, our 3-year-old mastiff mix! This handsome boy came to us ready to find a home with someone who understands his size, strength, and big-hearted personality. Because of his larger build, Oswald will do best with an adopter who is comfortable handling bigger dogs—especially as he continues working on leash skills and learning how to manage his excitement during playtime. He can have bursts of energy, and when he does, he absolutely loves heading outside for games of chase and fetch. The great thing about Oswald is that he knows how to balance his playful side with his calm one. After he’s had his fun, he’s more than happy to settle down beside his person for some quality cuddle time. In fact, his favorite thing in the world might just be a good belly rub! Oswald is currently working on potty training and learning basic commands, but he’s not quite there yet. He’ll need a patient and consistent home that’s willing to continue his training and help him become the best version of himself. With the right guidance and a loving home, Oswald has all the makings of a loyal, fun-loving companion who will bring both energy and affection into your life.

Story

Meet Lucky 🐾 Portuguese Mastiff · 8 years old · loves everyone he meets Lucky earned his name the day we found him. He'd been thrown away in the trash in Spain, and he was the very last of his group still waiting for someone to choose him. We did, and he's been the luckiest thing to ever happen to us ever since. For a big mastiff with a hard start in life, Lucky carries zero baggage. He is gentle and easygoing with people, with other dogs, and with every animal he meets. There isn't a mean bone in him. What makes Lucky special is how completely he gives you his heart. He's the truest best friend a person could ask for, the kind of dog who wants to be wherever you are. His all-time favorite spot in the world is curled up under your legs, fast asleep, happy just to be close. At 8, he's settled, affectionate, and ready to love his next family as fully as he's loved ours. Lucky is looking for a home where he can stay near his people and be the loyal shadow he was born to be.

Story

I’m a big boy with an even bigger heart, ready to be your most loyal companion. I’m the perfect mix of laid-back cuddler and devoted guardian. During overnight stays in a home, I proved to be a wonderful houseguest—fully housebroken, well-mannered, and content relaxing on a comfy dog bed or sleeping at the foot of your bed.I walk beautifully on a leash, take treats gently, know how to sit and give my paw, and love chewies, TV time, and plenty of belly rubs. I enjoy outdoor adventures, but I’m just as happy spending a quiet evening by your side.I’m deeply loyal to my family and can be uncomfortable around strangers, so I’ll do best with an experienced adopter who understands guardian breeds and can provide a calm, structured home. For vet visits and other handling, I’ll need a muzzle and sedative to help keep everyone safe and comfortable.At nearly 100 pounds, I’d love a home with a fenced yard or space to roam. I’m happiest as the only pet, and I do enjoy digging, so a perfectly manicured lawn probably isn’t for me. I also love water, but it’s best if I skip playtime with the hose because I get a little too excited!I know I’m not the right fit for everyone, but if you’re looking for a loyal, loving companion with a big heart, I just might be your perfect match.All of our dogs and cats are spayed/neutered, up to date with age appropriate vaccinations, heart worm or feleuk/FIV tested, fecal tested, rabies and tag, and microchipped before being placed in your home. Our adoption fee helps cover this cost.

Spayed or Neutered,

Story

Winnie is a beautiful 6-year-old sweetheart with a gentle soul and a heart full of love. She’s the definition of a calm and easygoing companion, happiest when she's curled up beside you enjoying a peaceful day at home. This big baby isn't overly energetic and doesn't demand constant attention. Instead, Winnie shows her affection by simply being near her people. Whether you're reading, watching TV, or working from home, she'll gladly keep you company and soak up the quiet moments together. Winnie isn't the biggest fan of change and may need a little time and space to adjust to new surroundings. Once she feels comfortable, her loving personality shines through. She doesn't actively seek out lots of interaction, but she appreciates having a patient family that understands her gentle nature and allows her to settle in at her own pace.
