After your application is approved, the foster parent for the dog you have selected will contact you to answer any questions you may have and determine if that dog is a good match for your family. If you have no particular dog in mind, we will be happy to keep your application on file and notify you if the right dog should come into rescue. Catahoula Rescue of New England is an all-volunteer group. Dogs in our program are fostered by volunteers. The foster homes care for our dogs as if they were their own. All dogs have received vaccinations appropriate to age and are spayed or neutered. Leo’s adoption donation is $300 which includes Rabies, DHLPP, Bordetella, fecal test, heartworm test, is on preventative, microchip and Neuter depending on age at time of adoption. If the dog is too young for a spay/neuter, then they will be adopted with a spay/neuter contract and deposit. We do not have a physical shelter; all our dogs are fostered in individual foster homes across the New England and Canada.

Story
**🐾 Meet Thomas! 🐾** **Breed:** Border Collie Mix **Status:** Eagerly searching for a loving home where he can be your loyal sidekick! **Background:** Say hello to Thomas, the sweet and lovable Border Collie Mix who’s always up for an adventure—or a nap, depending on how many treats he’s had! At around 2 years old and weighing 50-55 lbs, Thomas was found wandering the streets of Memphis, probably on a quest for the ultimate belly rub. **Personality:** This charming goofball has a talent for making friends wherever he goes, and he’s not afraid to show it with a little happy dance for treats! Already potty trained and a leash-walking superstar, Thomas is your perfect sidekick, whether you’re off on a grand adventure or simply lounging on the couch binge-watching your favorite show. With his calm and brave personality, he’ll be your loyal companion in all things—especially if there are snacks involved! **Ideal Home:** Thomas would flourish in a nurturing environment where he can share his life and continue to grow, ideally with a family that appreciates his affectionate nature and has plenty of treats to spare! Once adopted, Thomas will transport with Rescue Vet Transport to her new forever family ( Transport is an additional $185). If you would like to make her a part of your family please follow the link below to our adoption application. Please note, our volunteer team works very hard and they are very responsive so please submit your application only when you are ready to welcome your new furry friend. https://new.shelterluv.com/matchme/adopt/BCAR/Dog

Story
  This darling little 17 pound 2 year old girl is called Happy Heidi and she has a little mixture of what we call…..”adorable” genetics.  Maybe a little Jack Russell and a little Cairn Terrier?   Whatever it is we know that you will be delighted to bring this girl home to your family life any way you look at it.  She is good with other dogs, no matter how big and we have not seen her with cats.  She is working on her housebreaking and crate training.   She is not a dog for an apartment as she will bark if left in a crate for hours on end.  She is a busy girl that loves to be outside running her foster home’s fenced yard.  She is a cuddler and loving girl that will be someone’s shadow and adoring companion.  She is pretty good on a leash but could use some polishing.    She was found as a stray and would love to have someone home more than away for a 9 hour work day.  This little girl is pure gold and a joy to have around.  If you are interested in adopting or knowing more, please contact 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.comMay 4, 2025, 8:53 pm

Story
**🐾 Meet Walter! 🐾** **Breed:** Border Collie Mix **Status:** Looking for his forever family to share adventures and snacks! **Background:** Introducing Walter, the charming Border Collie Mix with a heart-shaped marking on his head that makes him look like he’s always ready for a romantic comedy! At around 2 years old and weighing in at 50-55 lbs, Walter was found roaming the streets of Memphis, likely pondering the meaning of life—or just sniffing for the best food truck. This clever pup is fully vetted and has mastered the art of potty training, though he might still be working on his PhD in “sniffology.” **Personality:** While he may be a bit timid at first, once he warms up to you, prepare for a love fest! Walter LOVES toys and will happily entertain himself with a squeaky ball or a tug toy. He adores belly rubs and will roll over with enthusiasm, ready to soak up all the affection you have to give! Walter is a fetch aficionado, chasing balls like they hold the secrets of the universe. He walks like a pro on a leash but occasionally stops to catch up on the neighborhood gossip—because who wouldn’t want to know what the squirrels are up to? With a gentle demeanor and a knack for cuddling, Walter is ready to steal your heart and your snacks! **Ideal Home:** Walter would thrive in a loving environment where he can continue to play and grow, ideally with a family who enjoys outdoor activities, treats, and plenty of toys! Once adopted, Walter will transport with Rescue Vet Transport to her new forever family ( Transport is an additional $185). If you would like to make her a part of your family please follow the link below to our adoption application.

Story
Ready to be your new best friend! Chief is a charming 4 year old mix breed dog with a sweet bully face that will steal your heart. He's an inquisitive and loyal companion who loves to be with his person, whether you're hanging out at home, running errands, or going for walks. Chief would thrive in a family that is ready to include him in their daily activities and trips. He currently goes to work with his foster mom daily and enjoys their morning stops for puppuccino's and mid-day walks. Chief is happy to cohabitate with medium to low energy level dogs and has gotten along with adult, seniors and little dogs! Chief does not care to engage in play with other dogs and would do best in a home without large size male dogs though has done well being walked past larger male dogs and meeting larger calm males in a controlled setting. Chief is both house and crate trained, and he sleeps soundly at night in his big dog bed. His favorite toys include Kongs, balls, and rubber chew toys.  Chief does not know how big he is and may be too much for small kids and would recommend a home with kids aged teen and above.  He cherishes his people and delights in snuggles and belly rubs. If you're looking for a loyal and loving companion, Chief is ready to join your family and share in all the fun and adventures!  Don't hesitate to send in your application for Chief at https://underhoundrailroad.org/adoption-application/. Chief is currently being fostered in North Carolina and may transport along the East Coast as far North as Maine to his adoptive home.  See more about the daily foster life of Chief with the following link!  https://www.facebook.com/BrittanysFurryFosters/May 4, 2025, 3:28 am

Story
  Lady Vanilla is one of the most beautiful and lucky former breeder dogs on the planet.  This 10 pound, 5 year old beauty was found in a disgusting garage with other female Miniature Poodles, living in total neglect and almost unidentifiable as to their gender due to the matted fur.  Her coloring is cream with light brown spots that is so soft and pretty.   After being shaved down her blue eyes stand out even more and as her fur is starting to come back in so clean and fresh, she just dances through life with a joy and freedom to really live in comfort.  Sweet and Loving are the two best words to describe Lady Vanilla. This 5 year old Miniature Poodle is thriving in her foster home. She is slowly gaining much needed weight and is working hard on perfecting her potty training .  For years she has lived in kennel and crate with no outside experiences.  This girl is everyone’s friend, dogs and humans.  She has even started playing with the other dogs and toys and it is so precious!!! When she first arrived she had no interest in toys. She has now picked out a stuffie she likes to throw around and she is becoming playful puppy she never had the chance to be. Of course Lady Vanilla loves being outside for the first time in years.  She is learning leash manners.  Her favorite thing is your attention and to place her front paws on your knee to get pets and hugs.  Her soulful eyes tell how much she wants to be loved and give love.  If  you are wanting to make this girl’s life a dream resurrection, please write to us at Critter Cavalry Rescue,   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.comMay 3, 2025, 8:46 pm
