Story

I am 53 lbs, and I am looking for my forever home. Adoption Donation: $450 Shy is a beautiful girl with a stunning brindle coat and a gentle, sensitive soul. True to her name, she can be a little shy at first and may need a minute to warm up to new people. But once she feels safe, her sweet personality shines through. Shy loves affection and will happily lean into you for pets once she trusts you. She has such a tender heart and just wants to be close to someone who cares about her. She came to us when her owner sadly became homeless, and the change has been scary for her. Shy is simply looking for a safe, loving home again — a place where she can relax, feel secure, and be someone’s beloved companion. With a little patience and kindness, Shy will reward you with quiet loyalty and lots of love. All dogs are microchipped, neutered, current on all vaccines, heartworm tested (if age appropriate), and up-to-date on preventatives at the time of adoption. All household members and any dogs from the household need to be present to be able to adopt. A photo ID will be required at the time of adoption. Appointments are recommended. All applications are considered general. Specific animals are NOT put on hold for adoption.

We also cannot guarantee the ages of our adoptable animals or how large puppies will be when fully grown. We look forward to seeing you soon!

Story

Hi, I’m Orville. I am a senior boy looking to relax in a home for my golden years. I will need typical senior care special needs. Dog’s Name: Orville Location: St. Joseph, IL Date of Birth: 06/28/2017 Gender: Male Breed: Mastiff Mix Color: Brindle Dog's Weight: 118 Gets along with: Dogs?: All Dogs Cats?: All Cats Kids?: Have not tested with kids Training: Leash trained: Walks loose on leash Crate/Kennel: Goes into crate/kennel on command Potty trained: Indicates a need to potty and doesn’t have indoor accidents Car: Rides Well in car Meet Orville Orville is the definition of laid-back love.This tall, gentle boy is happiest right by your side — truly your shadow in the very best way. Whether you're moving from room to room or enjoying a quiet afternoon, Orville will calmly stroll along beside you. He’s a pleasure on walks and just as easy in the yard, where he prefers to stay close rather than wander. Orville is wonderfully quiet and only speaks up when it’s time to head outside. His house manners are impeccable — he has his potty routine down perfectly and hasn’t had a single accident in foster care. He politely sits for his food bowl and treats, and at this stage in life, he’s more about companionship than chaos. While he may be a little slower these days, that just makes him an easy keeper and an incredibly devoted companion. Orville is quiet and well mannered, great on walks, fully house trained, does not require a fenced yard, will do well as an only dog or with a calm buddy, and an excellent choice for a first-time giant breed owner. Orville isn’t looking for adventure — he’s looking for connection. If you’re hoping for a steady, gentle presence who will faithfully follow you through life’s simple moments, Orville is ready to be your loyal best friend.

Story

Looking for a gentle giant to complete your family? Say hello to Duke, an adorable two-year-old Mastiff mix who's ready to fill your home with love and joy! This big-hearted boy has so much affection to give and is eagerly waiting for his forever family to come along. Inside the home, Duke is already a model citizen in many ways. He's fully house broken, comfortable in his crate, and absolutely adores being around his humans. Like many young dogs his size, he's still growing into his massive paws and personality. Duke would benefit from some continued reinforcement of his basic manners - he's quite strong on leash and gets so excited during playtime that he sometimes jumps up or gets a bit mouthy when his enthusiasm takes over. Duke would thrive with a family who has previous large breed experience and is willing to invest some time into his continued training. Due to his size and exuberance, we're looking for a home without children under 10 years old. He's not trying to be rambunctious - he just doesn't always realize how big he is! When meeting new dogs, Duke can be a bit unsure of himself initially and can be slightly reactive. The good news is that after a quick, proper introduction, he does wonderfully with other canines, especially female dogs. He does get excited around toys and food, so clear boundaries are important. Surprisingly, this big boy LOVES cats and would happily share his space with a dog-savvy feline friend! If Duke sounds like the perfect addition to your family, please contact us today. This lovable boy can't wait to meet you and show you just how much love he has to give! To ask about Duke, please contact us directly by calling 847-338-3252 or emailing info@redemptionroadinc.org. _____ See what's new with our rescue including updates on our animals and upcoming events: https://lnk.bio/redemptionroadinc Facebook: https://www.facebook.com/R4inc/ Instagram: @redemptionroadinc Our trainer's Instagram: @fullcircledogtrainer March 7, 2026, 7:33 pm

Story

Meet Sam! Sam is a very handsome pup, estimated at about 3 years old. He’s thought to be a Mastiff Mix, but, rather small for the breed. Sadly, Sam found himself at an overcrowded noisy animal control facility down south. He deserves a forever home and family of his own, and we want to help him get there!! This precious pup absolutely loves people and is good with older kids who are respectful of dogs. We expect he is good with lower energy dogs. Dogs who are too active might scare him and cause him to react. Sam absolutely loves belly rubs, and treats too! He's a little rough around the edges in terms of training but clearly is eager to learn. Sam is in overall good physical shape however he does have some vision issues causing him to sometimes miss things coming his way….this is why we expect he’d be scared by higher energy dogs, and high-activity youngsters. Sam is neutered, up to date on vaccinations, microchipped, heartworm negative and on preventative. We would still like to get Sam to an eye specialist for a comprehensive examination of his eyes/vision. If you’d like to add Sam to your family, please contact BAARKDogRescue@gmail.com or 847-852-0895.
