Story
This sweet litter came to us from a rural shelter in Mississippi. They are all so sweet and well-socialized and would make a great addition to any family. They appear to be terrier/border collie mixes, and are the happiest puppies you will find! They are crate trained and don’t make a peep all night. They have also mastered the doggy door in their foster home. A few key notes about our Rescue… 1. All of our pets start their journey in Memphis Tennessee. 2. No monies exchange hands until the pet has arrived 3. Once adopted, our pets can be transported to Denver, Colorado, the Midwest and all of the north eastern states. 4. We have a Facebook page and an Instagram page. You are welcome to visit to see some of our newly adoptive families. 5. We have been rescuing and transporting pets for 15 years. Transport is an additional $185

Story
  When you first meet Frejo, there’s something about him that feels different—like you’re looking into the eyes of a puppy with an old soul. This incredibly handsome Border Collie mix, born around February 5th, has the look of a little black bear with his soft, fluffy coat and thoughtful expression. Frejo came from Kentucky with his four brothers, all sharing that striking black or black-and-white coloring, but there’s something uniquely special about him. At around 12 pounds now, he’s expected to grow into a stunning 45–50 pound adult—your future “black nugget of perfection.” But Frejo is more than just good looks—he’s a thinker. A smart, observant puppy who takes in the world around him and responds with curiosity and heart. He adores snuggling with his foster mom and has become quite the star during puppy yoga sessions, happily soaking up attention, pets, and love from everyone he meets. Watching him romp around with joyful zoomies is pure happiness in motion. Like any young pup, Frejo will need continued guidance, structure, and training—but he’s already off to an amazing start. He’s almost fully housebroken, crate trained, and eager to learn (he even figured out how to get on the bed in under a minute!). He plays beautifully with other dogs and would thrive in a home ready to nurture his intelligence and loving spirit. Frejo would make a wonderful addition to a family with respectful children and would especially love a fenced yard where he can safely run, play, and embrace his Border Collie energy. If you’re ready to welcome a loyal, joyful, and deeply special companion into your life, Frejo is waiting for you.To learn more or apply, please contact Critter Cavalry Rescue at ccrtennessee@gmail.com. Be sure to include your location—Frejo is fostered in Tennessee, and transport is available to multiple northeastern states every weekend.   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 1, 2026, 12:03 pm

Story
Our extremely handsome Border Collie mix boy is called Bear Bear and he is a little guy who was born around the early week of February and he is ready to energize a new family at their very core.   He is so happy and loving and at 13 weeks he is 13 pounds and on his way to be a 45 pound adult dog.  His ready smile and curious nature are just a joy to behold.  He was brought to the Critter Cavalry Rescue fold and to a foster home after he left his KY Momma who Critter Cavalry paid to have spayed and fully vetted as a gratitude to have the puppies.  Bear Bear is just an engaging and warm little puppy who has a wonderful smile and beautiful markings that promise him to become a handsome Border Collie mix boy who will turn heads.   Bear Bear is still working on potty breaks and almost 1000% there.  He just needs a willing and kind  family who are great at training and being a loving group who are patient. Sweet Bear Bear is a willing soul that wants to be your best friend in life.  He is happy and handsome and in the time of his life to be molded and polished in to a fine and loving companion to a wonderful family. .  If you are ready to take on the role as guide and parent to Bear Bear please write to Critter Cavalry Rescue at ccrnewengland@gmail.com    He is ready to go NOW! 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 1, 2026, 12:03 pm

Story
  Meet Butters Butters is a playful, expressive Border Collie mix pup with a big personality and an even bigger heart. He’s currently working on crate training, potty training, and learning how to walk on a leash—he’s not quite as far along as his other foster buddy Waffles, but he’s making steady progress every day.  Born around Feb. 5th of 2026, this boy is destined to be a very handsome semi-long haired adult boy that will reach the medium range of 50 pounds. One thing you’ll notice right away is that Butters has a lot to say with his voice. He’s more vocal than your average puppy and loves to growl and “talk” during playtime—but it’s all in good fun. It’s just his way of getting into the game and showing his excitement. Butters plays hard with his foster siblings and gets along great with just about everyone—kids, cats, dogs, and adults. He’s social, friendly, and happy to be part of the action. When it’s time to eat, he’s polite and shares his dinner nicely with others.  The Border Collie breed is an active and very intelligent breed of dog.  Butters would benefit from a fenced yard and constant socialization with lots of people and lots of dogs to play with often.  Daily leash walks is great for this breed and it creates such a good bonding time for the owner to establish a closer relationship and affirming the position of who is the leader in the relationship....you and human.  If you’re looking for a fun-loving, energetic pup who will keep you entertained and grow alongside you then Butters could be your perfect match.  Please email Critter Cavalry Rescue for more information 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 1, 2026, 12:03 pm

Story
  Meet Tom — the life of the party wrapped in puppy fluff! This confident, spunky Border Collie mix is bursting with personality and keeps the fun going from sunup to sundown. Whether he’s romping around with his puppy crew or proudly parading through the house with his latest “treasure” (yes… usually a sock), Tom brings laughter everywhere he goes. His signature victory strut? Iconic. His pouty little face when he wants his way? Absolutely irresistible. Born around February 5th, Tom is expected to grow into a handsome 45–50 pound adventure buddy with a soft, slightly longer coat that’s just begging to be pet. He’s already off to a great start—he knows how to sit and is eager to keep learning, especially if treats or praise are involved! Tom loves his people just as much as he loves playtime, and he settles nicely in his kennel when it’s time to recharge. He’d thrive in a home with a fenced yard where he can zoom, explore, and burn off that fun-loving energy. Add in daily leash walks, and you’ll quickly become his favorite person (and fearless leader). If your home could use more laughter, more energy, and a whole lot of puppy charm—Tom is ready to deliver. Email Critter Cavalry Rescue at ccrtennessee@gmail.com to meet this unforgettable little guy!   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 1, 2026, 12:03 pm

Story
  Meet our wonderfully handsome Border Collie mix boy puppy named Waffles  Waffles is as sweet as his name and ready to find his forever home! This lovable guy is doing great with both crate training and potty training, and he’s already showing what a good housemate he can be. He loves to play hard with his foster siblings and has a fun, goofy energy—balanced by his gentle side, like happily sharing dinner without a fuss. His current favorite “toy”?   An old Croc… and honestly, it’s his prized possession. Waffles should grow to be a 45-50 pound adult Border Collie mix and he will be the smartest and most loving companion you could ever own.  He is in his high learning phase and still learning the ropes when it comes to walking on a leash and he’s making progress every day. He’s never met a stranger and loves to be told how handsome he is. He is so friendly, trusting, and eager for attention. If you’re looking for a playful, sweet, and loyal companion who just needs a little guidance as he grows, Waffles might be your perfect match. If you are interested in this boy puppy please email 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.comMay 1, 2026, 12:03 pm
