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.April 26, 2026, 9:08 pm

Story
Brittney (aka Brit Brat) Almost 7 year old boxer/pitbull/bully mix. She is good with kids, she loves to snuggle and sleep in bed with her humans. I took her in because she needed a home quickly or she would have been surrendered back to the shelter. I did not know much about her. I was told she is good with cats BUT she is only ok with one of my confident cats, she is not good with my scared cat. She strongly senses emotions so if something is scared of her, she wants to chase it. While she gets along with dogs, she's better off not living with any dogs at all as she wants all of the attention and space to herself. She is ok with play dates with submissive dogs. She is a leash puller, we are consistently working on that but she is strong and I don't recommend children or elderly hold her leash for that reason. She is muzzle trained and great with nail trimmings. Timid when she isn't familiar with her surroundings but once she warms up she's good. No known health issues

Story
Riddle is an energetic girl who is highly affectionate and needs a steady routine. She is almost four years old and loves snuggling. My husband and I bought her, as a puppy, from close friends that breed boxers. She has been living harmoniously with another dog and two cats until recently. She has been displaying aggression with the other dog in the house when food or treats are around. She is very loving, goofy, and sweet otherwise. We would love to find her a forever home with a family that is patient, active, and attentive to her needs.

Story
  Hey there… I’m Turbo.   I’m a 3-year-old, 47-pound Pitbull mix with a handsome black-and-white coat and a smile that seems to win people over pretty quickly. I ended up in the shelter because my dad felt I was spending too much time alone in my crate, and he wanted something better for me—a home where I’d get more love, time, and attention. I’m hoping that person might be you.   I used to be housebroken and crate trained, and while shelter life has changed my routine a bit, I’m a smart guy and should pick things back up in no time with a little consistency.   What really matters most about me? I love people. I’m friendly, affectionate, and I get along great with other dogs and kids. I’m the kind of dog who just wants to be part of the family—whether that’s playtime in the yard or relaxing by your side.   Summer is right around the corner, and I can’t help but dream about spending it with my very own forever family. Maybe that could be with you?   Let’s meet—I’d love to show you what a great companion I am.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.comApril 26, 2026, 9:08 pm
