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
Hello! This is Kori. She is 5 yrs old. An sweet energetic girl. She loves people and is also very affectionate. Kori came to me as a boarding and daycare client however her previous owners went through some life changes and couldnt keep her. They were considering giving her to the shelter however I didn't think she would do well in that environment. She does get nervous in new noisy places so i decided to foster. I run a boarding business so shes been around all size dogs. She does well with male dogs. Other females take some warming up to but in time she's ready to play. She has been around small children via her previous home and loves children. She does know the basics (Sit, Stay, Down etc.) She is house and crate trained as well. She is an free adoption. She is coming with everything needed (Beds, Crate, food). I am also offering to help pay 50% towards training to help her transition into her new home. Kori is such a good dog. She would make a great addition to the family.

Story
fam, what is up? i am piper, legitimately the coolest and nicest dog in town but actually … i am literally THAT guy. i’m pretty easy going, good in the car, and on the couch. that new netflix show that’s def gonna be coming out about the karen dever case? i will watch it with you. fr. even if you’re already following it on tiktok. i’ll listen to you talk about it AND i will watch the entire show with you and still act cool with it. so you know…if you’re like interested or whadeva, tap my line and let’s be besties for the resties 🫶🏼 ciao, piper What the people have to say about me: Meet this handsome, laidback boy who's ready to steal your heart! Piper is a true gentle giant, content to lounge and cuddle or play with his favorite toys. He's a go anywhere kinda guy (brewery/patio approved!) and he's got a smile that will melt your heart! Piper is a loving boy who has shown himself to be a truly medium energy fella - a couple of average walks, some playtime, and something to engage his brain and he's good to go! Piper is also quite the paradox - on one hand he is so smart and eager to please! He knows sit and paw, seems to know to lie down and even comes back when called. On the other hand, this poor guy couldn't figure out how a kong works! It's okay Piper, we get it. You're book smart and might just lack some commonsense! Piper loves to chew and is an expert at defluffing a good stuffed toy. He loves his playtime with his doggy pals equally to his cuddles with his human companions. Swiper says there's no such thing as being too big to be a lapdog and he's always ready to melt into you and offer his belly for some rubs! With his sweet disposition and easygoing nature, he's looking for a loving home where he can be your best friend and a cherished member of the family. Piper is learning that sharing is caring and is readily trainable. He has a chill demeanor and is a joy to be around! Piper's got a heart as big as his head and is just waiting to adore his forever family with!

Story
https://foha.org/pet/queen2023/ All hail me, your Queen! Hey there! My name is Queen, and I am a big, beautiful pup with a larger-than-life personality and a royal charm. The great outdoors is where I truly shine—I absolutely love going for walks and can never get enough of them! Leash walking? Piece of cake! I’m always ready for an adventure. Hiking is one of my absolute favorite things to do. Whether it’s a winding trail through the woods or a peaceful park, I’m in my element. There’s just something magical about exploring nature—splashing my paws in streams, sniffing out all the new scents, and, of course, rolling in the grass (I just have to!). I’m also a fantastic travel buddy. Car rides? No problem! I’m happy to either gaze out the window, watching the world go by, or just settle in with a tasty treat. And speaking of treats… let’s talk food. I. Am. FOOD. DRIVEN. Seriously, if you’ve got snacks, you have my full attention. Training? Yep, I’ve had training sessions, and with the right motivation (ahem, treats), I’m eager to learn and show off my skills. But let’s be real—I like to think I’m the one in charge, so I need a patient and consistent owner who knows my breed and can keep me on the right track. I’ve been in the shelter for two whole years, just waiting for my perfect match. I may come off as a bit sensitive, so I’d thrive in a quiet home where I can feel safe and comfortable. But once I warm up to you? Oh boy, get ready for endless love, constant demands for attention, and yes—plenty of slobbery kisses! If you can handle that, I promise I’ll be your best girl. I’d do best as the only dog in the home, soaking up all the love and attention (because let’s face it, I deserve it!). A household without kids would also be ideal, given my size and my big, excitable heart. But don’t let my size fool you—I’m a total teddy bear and a great house guest. I love hanging out with my favorite people, cuddling up, and just being part of the family. If you’re looking for a majestic, affectionate, food-loving, adventure-ready companion, I’m your girl! Let’s take on the world, one walk (or treat) at a time. If you’d like to meet me, fill out an application (no obligation), and let’s make it happen. Hope to see you soon!

Story
Clover is a bright, silly, curious, & affectionate young Mastiff who has blossomed beautifully in foster care w/me. When she arrived, she didn’t understand toys, play, or how to simply be a dog. She flinched at every movement, yet her bubbly personality & gentle nature still shone through. Within weeks, she became a happy girl who loves fetch, learns quickly, & bonds deeply w/people she trusts. She does a happy dance when she sees her people or senses an upcoming walk. She is excellent on a leash & has strong recall. She came into my home 5 mths ago as a foster w/her companion Ginger after being removed from a home by Animal Control. I adopted them both, but a planned adoption fell through, & I am now struggling to meet their needs financially & timewise. This decision is especially painful after losing a beloved dog in June. Clover is highly responsive to training & eager to please. As a guardian breed, she can be protective but is an absolute sweetheart who deserves the perfect home

Story
Ginger is a gentle Mastiff who came to me from the shelter after being removed from a home by Animal Control. When she arrived, she was scared, shut down, & unsure of the world. With patience & kindness, she has blossomed into a snuggly, affectionate companion who wants nothing more than a safe, steady home & a trusted human to bond with. She is goofy, playful, & occasionally “talks back.” She communicates her needs well, although she can be a bit stubborn. Ginger shows many Boerboel traits, although her exact breed is unknown. She is excellent on a leash & has great recall. She was originally fostered with her companion Clover, & I ultimately adopted them both. Unfortunately, a planned adoption fell through, and I am now struggling to meet Ginger’s needs financially and time-wise. This decision is especially hard after losing a beloved dog in June. Though still cautious with new people—esp men—Ginger has an incredible capacity for deep connection. She is truly a diamond in the rough.
