Story
Ruthie is a 2-year-old, 60-lb Boxer mix with a gentle soul and a brilliant mind. Before coming into rescue, Ruthie lived on her own for at least 6 months, skillfully evading capture, multiple trapping attempts, and surviving in an industrial area of town. Fed by kind mechanics and workers, she learned how to stay safe, avoid danger, and always show up for food — and that intelligence still shines through today. After a dramatic capture, Ruthie has been in a foster home, where she’s proven to be a very polite houseguest. She is fully house-trained and, even at her scariest moments, has never shown a hint of aggression — no growling, no raised lips, just fear. Ruthie is shy and deeply cautious with people, but she is sweet, gentle, and incredibly observant. We would not be surprised if Ruthie spent some of her life in someone’s home.  This brainy girl reads the room like a pro. She knows when a human might approach and will quietly skedaddle to keep herself feeling safe. While she’s still very nervous about leashes and handling, she allows most people to gently scratch her muzzle, and she’s learning — slowly but surely — that human touch isn’t such a bad thing. Watching her progress has been incredibly rewarding, especially as she’s started to enjoy ear scratches and soft affection from her foster mom. Ruthie is a great pack dog. She does beautifully with dogs of all sizes and temperaments and enjoys playful wrestling with dogs her size, but doesn’t demand play.  She happily coexists with the resident Chihuahua in her foster home. Ruthie is calm and content indoors and also enjoys a daily visit to the dog park. She’s a quiet presence who’s perfectly happy lounging on a chair, listening to her foster mom’s Zoom calls, and soaking in the safety of home life. At home, Ruthie is her foster mom’s quiet shadow. She sleeps in her room, wiggles with excitement when she comes home, follows her around the dog park — and yet may still hop off her bed and slip away if that same foster mom walks toward her for a pet. With Ruthie, trust is built in tiny, meaningful moments, and every day brings progress. Because of her history, Ruthie is a high flight-risk dog, especially in the early days. She will need a very committed adopter with a securely fenced yard, experience with fearful or flight-risk dogs, and a willingness to use safety tools like GPS collars, double leashes, and secure handling. Strength matters too — this is a 60-lb girl who needs someone confident and prepared. Ruthie has been around children at the dog park and treats them like little adults — with polite, reserved hesitation. She is food-motivated, sweet, and incredibly smart. With patience, structure, and time, she has all the makings of a truly special companion. Ruthie is one of those dogs who, with the right adopter and a few committed months of trust-building, will become a dream dog. Watching her finally relax, feel safe, and just be a dog has been an absolute privilege — and we can’t wait to see her find the forever home she deserves. ccrnewengland@gmail.com PLEASE NOTE:   Our dogs and cats are fostered in Tennessee and can transport weekly up to the Northeast region.  Request an application and learn more about Critter Cavalry at https://www.crittercavalry.com/adoption.February 17, 2026, 10:23 pm

Story
  There are some things in rescue work that are simply impossible to understand. One of those things is how anyone could throw a big, beautiful black Boxer from a moving truck and drive away.   But that is how Troy’s story began. On a quiet country road, good people working in their yard witnessed the unthinkable. They saw a truck slow down just enough to push this large dog out onto the pavement. He hit the ground on his head, dazed and bleeding, while the truck sped off without a second glance. Confused and hurting, Troy didn’t know who to trust. It took time, patience, and soft reassurance before he would allow those same strangers to help him. When he finally climbed into their backseat, his big, injured head rested in his rescuer’s lap the entire drive — seeking comfort even after such betrayal.   Physically, Troy has healed well. His wounds have closed and his strength has returned. But emotionally, you can still see that he is waiting for someone to prove that he is safe… truly safe… forever. And here is the remarkable part — Troy is an exceptional dog.   He is sweet, obedient, and wonderfully behaved in the home. He does not dig, does not climb fences, and respects his space. He wants structure, kindness, and someone to belong to. While he can coexist with some larger dogs, he would truly flourish as the only dog in the home where he doesn’t have to compete for affection. Cats are not a good match for him. A securely fenced yard would give him the freedom to stretch his legs and enjoy life while feeling protected. Troy doesn’t need pity. He needs commitment. He needs a Boxer lover who understands the loyalty and devotion this breed gives and who is ready to return that devotion tenfold. Someone who will look into his soulful eyes and promise that he will never again be discarded or unwanted. We have helped him start over. Now we are praying the right person will step forward and give him the stable, joyful future he deserves.   If you believe you could be that person for Troy, please contact Critter Cavalry Rescue at ccrtennessee@gmail.com     PLEASE NOTE:  Our dogs are transported from Tennessee to meeting places in the states where we have posted.  Further information about us is given on our Adopt-A-Pet site.  The adoption fees vary and will be provided as well as noted on the application you receive.  Contact us at 615-661-5333 or ccrnewengland@gmail.comFebruary 21, 2026, 12:42 pm

Story
I'm Ellie! I love car rides, snuggling, chewing bones, playing ball and walks in the woods. I am very food motivated and eager to learn new things! I'm athletic and can jump short fences so I need a tall enclosure! I love to explore, but when its cold and rainy, I prefer to be inside and cuddle on the couch. I have successfully lived with three indoor/outdoor cats. For two years I lived with another dog, but we recently had to be separated for our happiness. A family member took me in, however, their health is declining and I need a new home. I am good on a leash and as long as other dogs keep their distance, I won't have a problem. I'm training to not bark at strangers on walks and need slow introductions with new people. I'm very sweet to people, but I need a household where I can be the only dog, with no kids and an owner who will be patient with my reactivity and anxiety. I'd be the best buddy for someone who lives out in rural Maine who loves to hike and enjoys solitude!

Story
Horace is a handsome three-year-old boy who made his way to us all the way from Texas and he’s ready to find a loving home to call his own! When you first meet Horace, he may be a little shy. New places and new faces can be a bit overwhelming for him. However, with a few tasty treats, gentle encouragement and a little patience, his true personality starts to shine. Once he feels safe and comfortable, Horace transforms into the sweetest, most affectionate boy you could ever hope to meet. He absolutely loves going for walks and will happily trot by your side, taking in the world around him. After a good stroll, Horace is all about cuddle time. He’s also playful and wonderfully goofy, sure to bring smiles and laughter to his forever family. Horace would thrive in a home that understands his sensitive side and is willing to continue helping him build confidence. With love, patience and reassurance, he’ll blossom into an incredibly loyal and devoted companion. Horace has spent some time in a loving foster home, and here is what they had to say; Horace is a gentle soul who would make an incredible addition to any home. He is leash-trained (excelling with his EZ-lead harness) and a polite playmate who respects the boundaries of older dogs. While he loves a good snuggle session, he’s also independent and enjoys his own space. Horace is trustworthy when left home alone; he has been given free roam of the house and has shown impeccable behavior. If you're looking for a well-mannered, loving companion, don’t miss out on Horace, he truly is the perfect pup package!

Story
  Meet Bimbi – Your Loyal, Lovable Companion in the Making   Bimbi is a stunning, 3-year-old spayed beauty weighing in at around 40 pounds. With her regal looks and soulful eyes, she turns heads wherever she goes—but it’s her heart that really makes her shine.   Bimbi has known what it means to be let down, having spent much of her life confined to a crate. Despite this, she got along well with the small dogs in her previous home and remained the friendly, affectionate girl she was born to be. Sadly, when her family fell on hard times, Bimbi was surrendered, and now she’s waiting for her true forever home.   She absolutely loves meeting new people and soaks up attention like sunshine. She adores hugs, belly rubs, kisses, and gentle brushing with a soft brush—she’ll even close her eyes in bliss. Her favorite spot? Anywhere you are.   While Bimbi might not know a ton of commands just yet, she’s eager to learn and food-motivated (she mastered “sit” in record time with a few treats!). She enjoys playing with toys and balls—fetch is a favorite, even if she doesn’t always return the ball right away. Treat-based games are another great way to bond with her and keep her busy.   She’s a big fan of cozy dog beds and fluffy blankets, though when bored, she may chew on them a bit—so she’ll thrive with love, structure, and plenty of companionship. Her happiest moments? Going for car rides with her people. It’s been a while since she’s gotten to feel the wind in her fur, and she misses it deeply.  Bimbi is ready to trade her kennel days for couch cuddles, backyard exploring, movie nights, and being your loyal shadow. She doesn’t think cats make good roommates, so a cat-free home is a must.   If you’re looking for a dog who will love you with her whole heart, who’s ready to learn, ready to play, and even more ready to belong—Bimbi is your girl. Come meet her. She’s been waiting for you.   Email us at ccrtennessee@gmail.com    PLEASE NOTE:  Our dogs are transported from Tennessee to meeting places in the states where we have posted.  Further information about us is given on our Adopt-A-Pet site.  The adoption fees vary and will be provided as well as noted on the application you receive.  Contact us at 615-661-5333 or ccrnewengland@gmail.comApril 26, 2025, 11:59 pm
