The Heart Behind the Pack: Meet Your Leader
Chelsea Callahan has always lived a life surrounded by paws, whiskers, feathers, and scales. Growing up in Hamden, Connecticut, her home was the kind of place where every creature seemed to find a welcome spot—dogs, a pet mouse, snakes, and just about anything else that needed love and a warm place to land. She quickly became the neighborhood’s go‑to animal person, the kid everyone trusted to walk their dogs, feed their pets, and keep their furry family members happy. That early passion naturally grew into her first job as a dog bather during her freshman year of college, and by sophomore year she was running her own small dog‑walking business while also caring for horses at a local barn. Animals weren’t just part of her life—they were her life.
The spark that eventually became Callahan’s K9 Camp arrived on an ordinary day with an extraordinary question: a neighbor asked if her dog could tag along on a hike with Chelsea and her own pups. That simple moment lit up something big. With her lifelong love of animals and her background as an athlete—rugby, lacrosse, and now a dedicated CrossFit hiker—Chelsea realized she could blend her passions into something meaningful. In June 2016, Callahan’s K9 Camp officially came to life, built on the idea that dogs deserve more than a walk around the block—they deserve adventure, purpose, and the chance to reconnect with their wild, instinctive selves.
When COVID‑19 hit, the business paused, but Chelsea didn’t. From 2021 to 2023, she also worked as a Veterinary Assistant in a 24-hour emergency veterinary hospital, caring for animals. In 2023 she worked for a local children's bahavioral school for a year then went back to Veterinary Medicine working as a Vet Assistant at a local General Practice in 2025. Gaining hands‑on experience in both clinical settings deepened her understanding of canine health, behavior, and safety. That time sharpened her skills and strengthened her commitment to giving dogs the safest, most enriching wilderness experiences possible. When she returned to her business, she came back with even more knowledge, confidence, and passion for the work she was meant to do.
Today, Callahan’s K9 Camp is built on Chelsea’s belief that dogs thrive when they’re allowed to be who they truly are—explorers, athletes, scent‑seekers, and social creatures who crave movement and connection. Through off‑leash hiking, structured pack adventures, and immersion in nature, Chelsea helps dogs find balance, confidence, and joy. Every dog is treated with the same love and respect she gives her own, because to her, they’re not just clients—they’re family.
Two very special dogs inspired this entire journey: Bree, her loyal Pit Bull, and Layla, her adventurous Greater Swiss Mountain Dog. Their love for hiking, swimming, and exploring the outdoors shaped the heart and soul of Callahan’s K9 Camp. Their spirits live on in every wagging tail, every muddy pawprint, and every dog who discovers the thrill of the trail.
RIP Layla (2007–2016)
RIP Bree (2010–2023)
Their legacy continues with every Nature Dog who joins the adventure.
Why I Do This…
There’s this moment on a dog’s face that just lights up — that little spark in their eye, that big goofy smile that says everything. When I take an urban dog into the woods, they’re often unsure at first. They don’t know how to climb over fallen trees, or swim across a river, or step into squishy mud, or run down to the water for their first sip of fresh, wild river water. But then I get to watch them come back to life. I get to see their brain switch from “city mode” to something deeper, older, more instinctual. They start thinking like a dog again. They start remembering who they are. And that moment — that shift — brings me so much joy.
Out there, they learn to problem-solve. They learn to trust themselves. And yes, sometimes the pack gives them the courage they need — like crossing a river for the first time. Dogs who were once terrified of water end up wading in on their own just to cool off. It’s incredible to witness.
I love living in a natural, holistic way, and the woods heal the dogs in a way nothing else can. Dogs who spend all day inside four walls, full of anxiety or pent-up energy, start to melt into themselves again after just a few hikes. Humans are built to walk long distances, and dogs — with their four strong legs — are built for even more. We’re all meant to travel, to move, to follow the next waterway. So I take them there: to the next river, the next stream, the next lake. They drink, they swim, they explore, and they reconnect with the world.
And being out there with them heals something in me, too. Caring for these gentle souls, watching them grow into the dogs I know they can be — that’s why I do this. It all comes back to that one moment, that spark in their eye that says, “I’m free.”
"My 6 year old female standard poodle has been walking and hiking with Chelsea, owner of Callahan’s K9 Camp, since 2017 and she LOVES this activity. What is the activity? Walks in the woods, including swimming when the weather permits, with other friendly dogs-this is a big favorite for my dog! How do I know my dog is happy with this service? First, when I say the name Chelsea, my dog jumps up and down and runs to the front door. Second, when my dog returns from her walks she is at first energized, sometimes needing a quick run around the yard to “cool down”, and then she comes in and takes a long nap (yay!!). Third, the Instagram videos Chelsea posts show all the dogs running and playing and having fun.
I also LOVE this service-my human experience includes great satisfaction with promptness and reliability, communication about scheduling changes/weather issues, my dog coming home clean (although not always totally dry, LOL!!), and the price, which is a steal for the level and amount of service. In addition to my current dog, I had another dog who walked with Chelsea. That dog was quite reactive so Chelsea took her on appropriate outings and showed her patience and consistency that helped improve her behavior. Although that dog’s life ended unexpectedly, I am profoundly grateful that she got to spend some of it with Chelsea and the dogs of Callahan’s K9 Camp. I give my highest recommendation to this business and its proprietor."

"The hiking adventures Chelsea leads are simply transformative for my pup. Seeing him enjoy off-leash freedom in nature gives me such peace of mind while I'm at work. He returns home happy, tired, and perfectly balanced."

5-Star Pack Parent Reviews
We love seeing our adventurers thrive! Here’s what our community of happy dog parents and their wilderness-loving pups are saying about their journey with Callahan's K9 Camp.
"Chelsea is well known in our neighborhood as the go-to person for pet care and dog walking. I travel frequently and she has taken care of my senior dog and cat countless times. I always know they will be safe and happy while I am away. My dog “dances” on her hind legs every time she sees Chelsea!
On my most recent trip, my dog became ill. Chelsea recognized her symptoms immediately and contacted me right away. She genuinely cares about her clients. She has a wealth of knowledge and a passion for animals. I can't recommend her highly enough."

She takes great pride in what she does, and you will not be disappointed with her service! I highly recommend her for any of your pet care needs"

"Chelsea is amazing with the dogs. She is very knowledgeable about all kinds of breeds and she uses that knowledge to help her better understand different behaviors. She is the leader of the pack and the dogs know it. I have gone on hikes with her with my dog and he always has a blast. She allows the dogs to be dogs. They play, run and enjoy be able to swim in the water along the paths she takes them on. She tries to bring the dogs to different places so they can have different experiences. She works on recalls and basic training skills during the hikes. She allows the dogs to play and have fun all while Keeping them in check and listening for her voice and her commands. The dogs love chelsea and really enjoy hiking and going for walks with her. They are always excited when she arrives to pick them up. She is a great all around person and friend and I would recommend her to anyone looking for a great person to walk, hike, or babysit their dogs."

"Chelsea has been taking care of our 3 dogs for 8 years. She has a key to our house. She is very trustworthy and reliable. Our pets love her and never are upset to be left with her! My neighbors have stated that she comes to let them out several times a day and takes them on extensive walks and plays with them in the yard. Not just a quick walk around the block! She even keeps my yard cleaned up from their waste. Chelsea has a great rapport and shows genuine concern and respect for animals. She works on training them as well. She has been a gem. I have recommended her to many neighbors."

"My puppy has been hiking with Chelsea and The Callahan K9 Camp for a little over 4 years. Chelsea came very highly recommended by another dog mom, so I jumped at the opportunity to sign my puppy up and I have never regretted my decision!
Chelsea is wonderful with my baby girl! She is caring, empathetic, and energetic! She treats Lucy like her own and exercises her until she is exhausted, which great for me! She always puts the safety of the dogs first and all the pups get along! She even takes great videos and pictures during the hikes so you see your pup in action. She is aware of the weather and her environment, so I know Lucy is always safe with her, which puts me at ease. I highly recommend her personally and professionally. Don't wait, sign your puppy up for hiking services today!!"
