Story
Rosie is a sweet, loving pup looking for the right home where she can feel safe, comfortable, and loved. She came into our lives in February after showing up in a family member’s yard. After several attempts to locate her previous family were unsuccessful, we welcomed her into ours. Rosie is incredibly affectionate with her people and has so much love to give. Unfortunately, she has had conflicts with our other dog that have escalated into fights. During one incident, a family member was accidentally bitten while trying to physically break up the dogs. Because of this history, we believe Rosie would do best as the only dog in a home with an experienced, responsible owner who can provide structure, patience, and lots of love. This is an incredibly difficult decision for our family, and our priority is finding Rosie the right home where she can thrive.

Story
Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $300(in TX) Out of state adoption fee is $550 (includes transport to your area)

Story
Finn may look like a rockstar with his striking Mastiff–Shepherd good looks, but at heart, he’s a big, soft lovebug. Weighing in at about 60 pounds, Finn has grown into a handsome boy with a beautiful gray and tan coat, soulful eyes, and an even bigger personality. Despite his star-quality appearance, Finn is more of a laid-back, easygoing guy—think Eeyore vibes, but with engines revved and ready to love. From the moment he wakes up, he’s prepared to shower his people with affection… and trust us, it’s A LOT of love! Finn does well with other dogs and does need a slow, proper introductions to new friends—both two-legged and four-legged. Once he knows you, he loves you deeply. He’s happiest when he has a buddy (human or canine) to share his world with. Affection is Finn’s specialty. When someone comes to greet him, he lights up, runs over with enthusiasm, and hands out slobbery kisses and big hugs like they’re backstage passes. His joy is genuine, his heart is huge, and he’s always thrilled to see his people. If you’re looking for a big, lovable, slightly goofy rockstar who will adore you endlessly, Finn is ready to take center stage in your heart. Local adoption only $300 (in TX)

Story
COREY – A Gentle Giant with a Heart of Gold   Corey is the kind of dog who makes an impression the moment you meet him. With his big, handsome frame and soulful eyes, he has the presence of a true gentle giant. But behind that strong exterior is a calm, affectionate dog who simply wants to be near his people.   Corey carries himself with a quiet confidence and a peaceful nature. He’s not overly demanding or high-energy—he enjoys the simple things in life like relaxing in the grass, soaking up the sunshine, and spending time beside the people he trusts. His steady temperament and gentle demeanor make him the kind of companion who brings a sense of calm wherever he goes.   Despite his large size, Corey is incredibly sweet and easygoing. He does well with other respectful dogs and would thrive in a home that appreciates a big dog with a soft heart. He’s the type of boy who will happily walk by your side and then settle nearby, content just to be part of the moment.   Corey is looking for a home that understands big breeds and can give him the love, stability, and space he deserves. In return, he’ll offer unwavering loyalty, companionship, and the quiet comfort that only a devoted dog can provide.   Corey is neutered, microchipped, and up to date on vaccines and preventatives. He will be fully vetted prior to adoption.   Location: Texas (available for transport) Adoption Fee: $350 plus health certificate and transport (if out of state – varies by location)   Adoption Process: The adoption contract and fee are finalized prior to transport. All Pep’s Pals Rescue adoptions include a virtual interview and video meet-and-greet.   Corey is ready to find a family who will appreciate his gentle nature and give him the forever home he deserves.   Apply to adopt at: pepspalsrescue.org/adopt   ##2541025##

Story
He is housebroken and crate trained and does great in a busy household. He was completely calm and quiet during my mom’s 80th birthday party—even with a loud Filipino family gathering and karaoke happening nearby. An 8-year-old autistic family member played with him through the crate, and he was happy and relaxed. He’s getting better on leash and will come back when called if he starts pulling. He may react to some dogs or small animals but is redirectable. He is very people-oriented, loves attention and wants to be near his humans, but will settle when it’s not available. He’s good with kids, probably 6+, because he’s gentle but doesn’t always realize how big he is. With other dogs, he seems more interested in coexisting than wrestling or playing. He needs a dog that respects boundaries and slow introductions are recommended. He’s very food motivated, although chicken may upset his stomach. He isn’t particularly interested in toys or balls. Car rides are his biggest challenge—he tolerates them but gets stressed, drools and doesn’t settle. Overall, he’s a sweet, affectionate, goofy guy who has made great progress and really just wants to be near his people.

Story
Meet this handsome, distinguished gentleman! This big, blue-gray boy has a powerful, muscular build, a broad blocky head, oversized paws, and the sweetest silvered muzzle that comes with age. At approximately 11 years old and 90–95 pounds, he has the impressive presence of a mastiff-type dog, possibly with Cane Corso ancestry. But don’t let his imposing looks fool you! He’s people-friendly and wonderfully unbothered by the dogs and cats around him. His deep, rumbling bark gives him a voice to match his impressive stature. This senior gentleman deserves a home that appreciates big dogs, mature-dog charm, and a personality that may be much gentler than his formidable appearance suggests. Please note: Simba is not neutered due to his age and associated risk
