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 $200(in TX) Out of state adoption fee is $450 (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 $200 (in TX)

Story

PLUTO – A Gentle Giant Who’s Learning What Love Feels Like Pluto’s story is one of quiet strength, resilience, and hope. When he was first found, Pluto’s body told a heartbreaking story—thin, weak, and covered in the marks of neglect, he had clearly been struggling to survive for far too long. Yet even in his frailest moments, his eyes showed nothing but kindness and a longing to trust again. With time, care, and steady meals, Pluto has begun to heal. His once fragile frame is filling out, his coat is regaining its shine, and his spirit is blossoming. Today, Pluto is discovering the joy of simple things—soft bedding, full bowls, gentle voices, and the company of people who see him for the beautiful soul he is. Pluto is a large, calm, and affectionate boy. He moves with quiet confidence and has a gentle presence that draws you in. He gets along well with other dogs, especially those who are respectful and laid-back like he is. He’s not demanding; instead, he enjoys just being near his people, resting his head close by, or soaking up a few moments of peace in the sun. After everything he’s been through, Pluto deserves a home that will offer him consistency, kindness, and the unconditional love he has always given in return. He is a living reminder that even after hardship, trust and joy can return with patience and care. Pluto 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. Pluto is ready to leave his past behind and finally experience the comfort of a loving forever home.

Story

Bertha’s Story Meet Bertha, a 3-year-old Mastiff mix with a heart as big as her paws. Bertha’s journey hasn’t been the easiest — she was found abandoned in an apartment after her owners moved out and left her behind. Thankfully, caring neighbors stepped in and did what they could for her before bringing her to a shelter so she could have a real chance at a better life. From there, Bertha went into a temporary foster home while waiting for a full-time foster, and that’s where her true personality began to shine. At first, Bertha was very shy and unsure, but it didn’t take long to see just how much love she had to give. With patience and kindness, she blossomed into the goofy, affectionate girl she truly is. Bertha absolutely loves to play and will never turn down a cozy lap to lay her big head on. She has lived with other dogs and has done well with them, but she would prefer a home without cats. When Bertha was rescued, she was very malnourished, so we are still working on helping her gain healthy weight. Her future family should expect her to be a big girl, likely around 110 lbs once she’s fully filled out — which just means 110 pounds of love. Bertha is looking for a family that will never leave her behind again — one that will give her the security, love, and couch space she deserves. In return, she’ll give you endless loyalty, laughs, and the sweetest snuggles. Could Bertha be the missing piece of your family?

Story

*Woof* I`m in a foster home. To meet me reach out to my foster caregiver at faithsanders25@gmail.comOnyx is a variety of quartz and symbolizes protection and strength. And yes, that is me, the beautiful Onyx with a strong heart and a willingness to protect our life together. Apparently, Onyx also symbolizes the absorption of negativity and if you have seen my super wiggles, then you will believe that I can do this. I am a whole-body expert wiggler and when you come home and see me wiggle, it will make your day (and your coming home will make my day). I will bury into your hand or body just hoping that you`ll give me lots of pets and cuddles. I am curious, friendly and a true delight to be around and so it is good that I am a big boy so there is just more delight of me. I have been enjoying my walks here and am looking to acquire basic doggie manners. I hear there are yummy treats involved -- and food is one of my favorite things in the world! Are you open to bringing a gorgeous and happy dog into your life? I may be the right fit!
