Story
*Woof* Meet me at 71 Oglethorpe St NW between 12pm-7pm daily!Meet Olive! Olive is a sweet and enthusiastic companion who loves greeting and welcoming her favorite people with a wagging tail and happy spirit. She enjoys getting out for walks and exploring the world around her, especially when there are plenty of interesting scents to investigate. Sniffing adventures are some of her favorite activities! On recent field trips, she loved hiking, sniffing, splashing in water, playing tug, and meeting new people. She was great on leash and great in the car (got right in, and was sleeping pretty quickly!). She occasionally got the zoomies which was the cutest. Olive LOVES toys! She loved playing with her pink elephant and rope toys. She`s also treat-motivated and knew to sit to get a treat. She`s a very loving dog and loves curling up with her person. `Overall, she`s just an absolute sweetie who loves napping just as much as she loves playing and zooming.`Olive is smart and a quick learner who`s eager to please, especially when treats are involved, so positive reinforcement training will continue to help her thrive. If you`re looking for a friendly, curious, and loving dog who will happily join you on walks and adventures, Olive may be the perfect match for your family!

*Woof* Meet me at 71 Oglethorpe St NW between 12pm-6:30pm daily!Sherlock was WTOP`s Pet of the Week! https://www.instagram.com/reel/Dd4mKy6M5Qs/?stkn=aXgwejJkbWZmbWc5After a recent field trip with Sherlock, a volunteer shared, we `had the BEST DAY EVER. He`s genuinely such a gentle, chill pup. He did great in the car, on walks, resting. No issues when we passed other dogs or people. He warmed up to us so quickly and was playful with his toys and then cuddly during rest times. WE LOVE HIM!!!!`The mystery our lovely Sherlock is trying to solve is which family or person will be lucky enough to spend the rest of their lives with them. Evidence he accepts in this process are treats, head scritches, and lovely walks. He scrutinizes each of these carefully and will then decide who the murder, eh, the acceptable family is. Sherlock is a handsome jet-black gentleman. He`s a settled character but definitely delights in spending time with his person. He enjoys receiving and showing affection (in the reserved British-gentleman way that suits his name). This boy is so easy going and great on leash. He`s also so gentle when he plays!Sherlock is easy to be around, and we expect him to be a perfect companion who will unearth all the hidden secrets in the neighborhood!

Story
Justice is a sweet, gentle boy with the most soulful eyes. While he can be shy at first, once he warms up to his people, he transforms into a total lovebug! He is incredibly cuddly and affectionate, and once he knows he is safe, his absolute favorite thing in the world is sharing some quality couch time with his humans. ​Justice is crate trained and adores other dogs—he truly loves having a canine companion. He has also spent time around small children and has done wonderfully with them. In his foster home, Justice has been making incredible strides: he has mastered going outside confidently by himself, has started playing adorable solo games of fetch by tossing his own tennis ball, and is a wonderful listener who redirects beautifully to a gentle "No thank you." ​As a sensitive guy, Justice does best when he can take his time and come to you for affection on his own terms. Because of this, he would thrive in a home with a confident, respectful second dog who can show him the ropes and help build his confidence. With a little patience and a welcoming heart, Justice is ready to show you what being a cherished family member is all about. ​Amazon wishlist for Justice: https://a.co/09FRXsIw ​ ADOPTION DISCLAIMER: At Perfectly Paired Pitties (P3), we aim to provide accurate information about all of our animals to the best of our abilities.

Story
Meet Hope — a beautiful Boxer girl who has already overcome so much and is finally ready for the happy ending she deserves. ❤️Hope is a 7-year-old purebred Boxer, but please don’t let that number fool you. This girl has the heart, energy, and playful spirit of a much younger Boxer. She bounces, prances, dances, and barrels through life with a zest that is impossible not to smile at. She is the kind of dog whose happiness is contagious.Hope came to Critter Cavalry Rescue during a heartbreaking time. Her beloved owner became critically ill and was ultimately unable to care for her, and when Hope came into rescue, she weighed only 35 pounds and was painfully underweight. Her owner’s greatest wish was that she would be given the best life possible, and that is exactly the promise we made to him.Today, Hope is a healthy 46 pounds and absolutely thriving in her foster home. She is currently living with several other Boxers and has fit right in as though she has always been part of the crew. She is wonderfully social and genuinely enjoys making friends. Dogs, children, adults — if you are willing to be her friend, Hope is ready to love you!Hope is also a very good girl in the house. She is completely potty trained, knows her basic commands, and is so well mannered that she does not need to be crated when left home alone. She is easygoing, affectionate, and responds well to gentle guidance.But what really makes Hope special is her spirit. She has been through a major life change, yet she has come through it with her joyful personality completely intact. She still believes the world is a wonderful place and that every day is an opportunity to play, explore, and love someone new.Hope would love an active Boxer-loving family who will give her plenty of playtime, attention, and opportunities to enjoy life. Another dog who appreciates a playful companion would be wonderful, especially one who doesn’t mind her endless Boxer enthusiasm!Hope has spent enough time waiting for her tomorrow. Now she needs the forever family who will give her the bright future her name promises. She is fully vetted, microchipped, thriving, and ready to make the next chapter of her life the very best one yet.If you think Hope could be the joyful, energetic Boxer girl your family has been waiting for, please email Critter Cavalry Rescue at ccrnewengland@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.comOctober 6, 2026, 6:55 pm

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.October 6, 2026, 6:55 pm

Story
House trained: Yes Energy level: Medium Noise level: Barks occasionally My foster guardian says: "My favorite thing about Rhiannon is everything about Rhiannon! She's the best!" Hi, I'm Rhiannon, and I'm a rockstar of a dog! Everyone I meet says that I'm the best girl, and my foster family sings my praises too! They're like my own personal hypemen! I'm a super sweet, happy, confident, well-behaved pup who gets along with everybody, human and canine alike. I absolutely love people and other dogs, and I'm always excited to make new friends! I can get a little extra-excited when greeting my new favorite people and pups, but it's just because I'm so happy to see everyone. I'd love to have a doggy foster sibling in my future home, though being an only child would be taking center stage...I'd be good with that! Some of my favorite things to do are play with my toys, learn new tricks, and cuddle with my foster family! They say that I'm always hopeful about being let in the bed to snuggle at nighttime, though my cuddle career has been couch-bound up to this point. I'm also super cuddly at home and love getting cozy with my people. I think if I keep turning on the puppy dog eyes (a special talent of mine), I'll crack them soon! I'm also a lover of all toys, and I have the best time ever chewing, squeaking, tugging, and snuffling with all my stuffed animals and tugs. Going for walks and being outside is another activity that I love, and can't wait to do with my forever family. I have lots of energy and am always ready to head out for a walk or a trip to the dog park! I like to observe the wildlife, sniff all the smells, and greet everyone we pass by. I'm especially fascinated by squirrels, and my foster family is helping me remember that they're best admired from a distance! I also have a curious side and sometimes think sidewalk treasures (including garbage!) look like very interesting snacks, so my humans will need to keep an eye on me during our adventures. If you're looking for a social butterfly of a dog, I'm your girl. Though I have lots of energy for walks and playing, I'm really a mellow girl at heart, and I settle down quickly for naps once the excitement is over. My foster family likes to brag about how smart and trainable I am, and it's true! I already know 'sit', and I'm working on 'shake' too. I'm also very good about going in my crate, and sleeping there overnight without a fuss. I'm also a good listener, and very attentive. I love learning new things, especially when treats are involved! I'm still learning that being apart from my people is okay, and my foster family has already seen me make great progress with this. The first time they both left the apartment, I let them know I missed them by crying for a while, but after that I was able to settle down after just a few minutes. My foster family thinks this is something that may take a little time and consistency, especially as I adjust to new places and routines, but I'm already showing them that I can learn! I'm also doing wonderfully with my house manners. The only accident I had was a little excitement pee on my very first day in my foster home, when everything was brand new. Since then, I've been accident-free! So, that's my artist CV! I'm the full-package, right? I'd be the star addition to any family, so apply to adopt me today!

Story
Meet a medium-sized, loyal, and affectionate companion with a moderate energy level who is looking for a dedicated forever home. She is house-trained, quiet, plays well with other dogs, and loves standard routines like eating right alongside her pack. She requires an adult-only home without children or seniors, as her intensity can be overwhelming for them. To ensure complete transparency, she is a reactive dog who has bitten in the past when feeling overwhelmed, unsupervised, or around unfamiliar people. She is not a bad dog, but she needs an experienced, attentive owner who can provide strict supervision, structure, and ongoing training to address behaviors like jumping or unexpected reacting to strangers. Using a preventative muzzle in public or new environments is essential. With clear boundaries, active management, and a committed, loving leader, her playful and protective spirit will truly shine.
