Sophie is a sweet girl. Born december 1st, 2024. I cant provide the needs she requires for her best life. Would love her to be on a farm with space to run. I have trained her to have the biggest heart! I love her so much i want the best for her, as much as it pains me. She deserves more than I can provide and I hope she finds a loving home.

Story
🐶 1.3-year-old Female American Bully Looking for a Loving Home An’an is a healthy, fully vaccinated female American Bully with vaccination records available 💉. She is not spayed yet, but I can help arrange the procedure before rehoming if needed. She has a gentle, friendly, and affectionate personality ❤️. She loves being around people, enjoys playtime, and adapts well to new environments with patience and care. She would make a wonderful companion dog 🐾 Due to my upcoming graduation and return to my home country ✈️, I’m no longer able to provide her with a stable long-term home. I’m hoping to find a responsible and loving owner who can give her the care, time, and companionship she deserves 🏡 Ideal home: stable living environment (house or pet-friendly apartment) with someone who can provide love, attention, and long-term commitment. Please message me if seriously interested.

Story
Cooper is a 5-year-old Ridgeback/Mastiff mix who forms deep bonds with his people. Once he trusts you, he is affectionate, loyal, goofy, and happiest by your side. He enjoys running in open spaces, relaxing at home, and spending time with those he loves. Cooper is a sensitive dog who struggles with fear-based anxiety around strangers, loud noises, and unfamiliar situations. He needs a calm, structured home with patient, experienced adults who understand dog body language and are willing to take introductions slowly. He currently lives with another dog and a cat and generally prefers a peaceful environment. He would do best in a quiet home without small children. Cooper is neutered, healthy, and up to date on vaccinations. His ideal home is a detached house with a fenced yard and someone who can provide consistency, stability, and understanding. For the right person, Cooper will be an incredibly devoted and loving companion.

Story
Buddy Holly Have you ever looked into the eyes of a dog? I mean really looked. Hi.My  name is Martha. Buddy asked me to  write his bio since his English is not good. Although I have never met Buddy, I have looked into his eyes in the photos taken of him. In them I have found kindness, earnestness, love, and vulnerability. I have owned and cared for three Brittanys from their youth to their elder years. Without a doubt, I can tell you that the elder ones are a delight and eager to please.  Buddy at 9 years is a liver and white Brittany mix currently being fostered in Michigan. He is curious and playful, but also has a mellow side to him.. In broken English Buddy tells me he loves to run around the yard with surges of  joyful enthusiasm. After his energy runs out, he likes to relax with a nap or snuggle.   Going for a walk is one of his preferred activities. His stuffed animals and squeaky toys are his treasures, and he can be seen showing them off with pride wherever he goes. He tells me that when he plays with his squeaky toys, he pretends to be one of them and tries to squeak back, hoping to sound like his namesake. However, he realizes this is a lost cause and contents himself with burping now and then. Buddy is house trained and crate trained. Since he is not a fan of other dogs,  he tells me he would be happy to be the only pet his home. He is informed me that he would prefer to be in a calm home with adults or older kids familiar with canine behavior who can give him the space he need and appreciate his relax relaxed way of life. Although he has not been tested with children, his calm and engaging manner would more than make up for this.  Buddy is a sturdy dog who is in excellent health and takes no medications. He is a serious alarm system. He will let you know if something out of the ordinary is going on around the house. He has an impish strain, such as digging when bored. He will be at his best if he has structured play time or organized activities to occupy his inquisitive mind. Buddy is a dog with healthy contrasts. He is able to juggle joy and companionship. He can be playful without being overwhelming, devoted without being clingy, and thoroughly faithful.  Buddy wants you to know the following:  " I don't drink alcohol or use illicit drugs. I don't smoke or drink coffee. I have never been arrested. You will find me to be of sound character. I may have bursts of enthusiasm, but I also like to snuggle on the couch and watch Netflix with you."   Could you be the one to give this sweet boy the forever home he deserves? Fill out an application at: https://nbran.org/adopt/adoption-application. Once your application is submitted the coordinator in the State where you reside will follow-up with you. Need to reach your State Coordinator, find their contact information here https://nbran.org/about/state-provincial-coordinators.   MI/Buddy Holly adoption fee is $275.00 which will help NBRAN cover the vetting costs and other expenses associated vetting and readying our Britts ready for adoption.   Don't live in MI or close by? No Problem!  NBRAN also has a wonderful transport team willing to help bring Brits to their new family, up to 1400 miles with the adoptive family being responsible for the last 100 miles, at no additional fee.

Story
Meet Your New Best Friend! Jayce is a 3-year-old Brittnay Mix who is looking for his forever home. While he might be a little shy when you first meet him, give him a moment to come out of his shell, and you'll find a funny, bouncy, and deeply loving companion. Jayce is a "paws-on" kind of dog! He is famous for his hugs and will spend his time trying to wrap his paws around you if he isn't already trying to curl up in your lap. He is the perfect blend of a lounge partner and a playmate. Because of his cautious temperament, Jayce has some specific needs to help him feel safe and successful: No Other Dogs: He prefers being the "only child" and can be reactive toward strange dogs. Quiet Environment: He would not enjoy the high-stress environment of a dog park. Patient Humans: He needs an owner who understands he needs to approach new things at his own pace. No Strangers (at first): He can be vocal with people he doesn't know, but his loyalty to his inner circle is unmatched. If you have the patience to let him blossom, you will be rewarded with a level of love and loyalty that only a dog like Jayce can give. He is ready to be your most devoted friend. Jayce's adoption fee is $325 to offset the cost of vetting and help other rescues in need. He is currently located in Georgia and can be transported up to 1400 miles via our Canine Railroad.
