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

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

*Woof* I`m in a foster home. To meet me reach out to my foster caregiver at vonfoer2@gmail.com!During a temporary foster stay, my foster said I`m a great dog. I came out of his shell very quickly and showed myself to be very friendly and sweet. I`m clearly people-oriented and eager to connect. I lived up to my reputation for good leash manners and really enjoyed a lick mat with peanut butter. I am the goodest boy, as at least 6 people here will confirm, and well-suited to be your new loyal companion. I love my daily walks and with me, you don`t need to have athletic ambitions and run for long stretches, but I`m always up for a well-paced walk with decent sniff breaks. I like this to be followed by a good snooze, please.I know some of the basic things, like sit, and am a good leash-walker, so we should be off to a good start when you take me home. Otherwise, I am a laid-back, easygoing pup who is always happy to be around his people. In sum, I am perfect -- and so ready to make your life perfect, too!ICYDK, `Bark Hamill` was the name of the dog of actor Mark Hamill, who played Luke Skywalker in the Star Wars franchise. Yes, I know, that dog looked a tiny bit different (small and white), but I am still pretty honored to be named after a pup that had such a famous dad!

Story

***50% of Piper's adoption fee is sponsored by Petfinder*** 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!
