Waitlists are now open for the fall/winter Labrador litter & the Saints Litter

We are committed to providing the best possible care for our dogs. Our AKC puppies are raised in a loving and nurturing environment, and we work closely with new owners to ensure that they have all the information and support they need. We will be around for our owners for as long as needed. Our dogs are given the best health care, training and nutrition as well as our puppies. We strive to for excellence.
"Your love, Lord, reaches to the heavens, and your faithfulness to the skies. Your righteousness is like the highest mountains, your justice like the great deep. You, Lord, preserve both people and animals." Psalm 36:5-6

We adhere to the highest standards when it comes to breeding dogs. We only breed dogs that are healthy, happy, and have the best possible temperament. We also follow strict guidelines to ensure that our home and our breeding practices are ethical and responsible. All our dogs are loved and live indoors - they are a part of our family and our heart.
I also follow "The Rule of 7's."
All puppies before 8 weeks will:
Meet at least 7 different people.
Drive in a car for at least 7 miles.
Been in 7 different locations with no risk to the pup. Eaten from 7 different containers.
Played with 7 different toys.
Played or taken away from littermates 7xs.

Since I breed 2 different breeds, our Dames and Sires have come from several different breeders. Our Male Labrador Retriever came from an extremely established and well-loved breeder in Oregon. You can find her information at www.silverandgoldlabradors,com
Our female Labrador Retriever also came from a breeder in Oregon; however, she has since retired due her business being lost during the fires in 2022.
Our chocolate female that is being trained in field and hunting comes from www.morrisonlabradorretrievers.com
Our female Saint Bernard is from a New Jersey Breeder who has since retired, and our male is from a Breeder in Pennsylvania, Misty Run Saints. Our newest member to the Marlow Hill breeder is Lady Maggie - a gorgeous Saint Bernard female from the well -established Cove Mountain Saints

As a Certified Animal Behavior Trainer, I am committed to insuring all of our dogs are given the best nutrition, training and care. With years of experience, I have a great understanding of their temperament, behavior, and health needs, which allows us to produce high-quality puppies that make great pets.

To ensure the breeding of quality puppies I am constantly expanding my knowledge of various breeds and behaviors. I have graduated from several programs and use this knowledge in my breeding practice. Being a smaller breeder, I spend a huge amount of time with my dogs ensuring they have a quality diet, daily enrichment and lots and lots of Love!
I continually attend training webinars through the AKC and other avenues to keep my training updated. This makes me available to help my families as questions arise. If you would like, I will be your breeder for life.
I also volunteer at the local Humane Shelter, utilizing my skills to improve the life of dogs less fortunate but still extremely valuable!
As a breeder I am committed to my pups and their new families - making myself available to any questions they may have.

Over the years I have been a loyal member of the AKC adhering to all rules and regulations regarding the breeding, training and caring for my dogs. All my dogs are medically sound and are under the care of Park Place Veterinarian in Swanzey, NH. They receive all necessary exams, shots and tests as needed to ensure they are in top health and produce healthy pups. All puppies are given a one-year genetic guarantee.
I believe that all dogs should go through the Good Citizens Program as they will go through life alongside humans. Ensuring your dog is well trained is essential to your dog having its best life! This training is easy and after a quick test, your dog is certified.

Mary thank you for a great experience. Your attention and nurturing of your pups certainly show in how well adjusted they are, "Jiggs" is a wonderful pup. He is so smart and loves his toys and going for walks. We just adore him and feel so lucky to have found Marlow Hill Breeders! Chip and Kathie Worthington.
"There are a lot of breeders out there, but if you're looking for a breeder that genuinely cares about her dogs and their puppies, I strongly encourage you to speak with Mary at Marlow Hill Breeders. We purchased a black lab from Marlow Hill Breeders and we're so grateful we did! Mary's experience as an animal behaviorist gave us the assurance, we needed that our puppy would have the best temperament for our son with special needs. Our puppy "Joy" is now 12 weeks old, and she is the smartest girl. She crate trained immediately and continues to astound us with her intelligence. She has been an absolute JOY to our family and we're confident she'll be an amazing companion to our son. Laura Hardiman

After losing our thirteen year old rescue in January of 2024, we started searching for a reputable breeder. Not an easy task! Our four year old lab Luke needed a companion…or so we thought. One evening we came across Marlow Hill Breeders. As we read the information, it became very evident that this was the breeder for us. Mary’s expertise in animal behavior, commitment and love for her dogs exhibits itself in each of her pups. They are social, happy and healthy little bundles of joy.
We had several conversations with Mary, but due to a prior family commitment, we would not be able to pick a pup up when they were being released. So, sadly we said no. That wasn’t the end of the story. A short time later I was checking Mary’s website, and she had one black female pup who needed a home. We didn’t hesitate to say yes, and
We had several conversations with Mary, but due to a prior family commitment, we would not be able to pick a pup up when they were being released. So, sadly we said no. That wasn’t the end of the story. A short time later I was checking Mary’s website, and she had one black female pup who needed a home. We didn’t hesitate to say yes, and we became members of the Marlow Hill family. It is such fun to send pictures for Mary to post and watching all the pups grow up.
Fast forward a year. We had no intention of adding another dog to our family. Yet there was that little yellow boy who had not been spoken for. So I called, sent a deposit and thought oh my! It was meant to be. He (Logan) and Leah (from Chloe’s first litter) are best buddies. Luke will join in on occasion but prefers to be in the tractor with his human Dad! So, all of that said, we couldn’t be more pleased with Leah and Logan, and the time and dedication that Mary and her husband put into raising these beautiful puppies. Lots of adventures ahead!

We have been so blessed to have Sirius (formerly known as Chase) added to our family. Our previous dog had passed 2 years prior, and we were ready for a new puppy., The opportunity arrived because there was 6-month-old puppy needing to be re-homed on the Marlow Hill Breeder FB page. Mary went above and beyond to help facilitate. All his paperwork was in order, and we found ourselves with a beautiful pup with shiny fur and no health or behavioral issues. He has adapted really well to his circumstances and is a very loving, affectionate dog. We couldn't be happier with the level of service Mary provided. Sirius was the missing piece to our family.

I will never be able to explain how thankful I am for Mary at Marlow Hill Breeders. It was a long year of researching different breeds and breeders. Looking for a cardiac service dog can be very tricky; however, as soon as I found Mary, she put my mind at ease. She walked me through all of her goals for each of her litters. She shared experiences people have had with her. She sent me photos every day, no matter how many times I asked. She was very patient and helped me decide on the perfect puppy that would make the best service dog. I cannot explain enough how perfectly Oakley has fit into my life. He’s already in training and knows all his tricks. He’s definitely the smartest dog I’ve ever come across. I could not recommend Mary enough. I’m forever thankful for Marlow Hill Breeders.

I cannot recommend Mary enough. We spent a lot of time researching breeders to find someone we truly trusted and felt comfortable with, and ultimately chose Mary, even though she was a four-hour drive away and there were breeders much closer to us.
From my very first phone call with Mary, I knew she was the right choice. Her practices are ethical, she is incredibly knowledgeable about the breed and the process, and most importantly, she is genuinely passionate about what she does.
Mary made us feel like part of the process from start to finish. Nearly every day, she sent updates, photos, and videos of the puppies. Because we couldn’t visit in person to choose, she Face Timed us, walked us through each puppy’s personality, and helped thoughtfully match us with a pup that fit our lifestyle perfectly. When it was time to pick up our puppy, Finn, Mary welcomed us into her home, where the entire litter was happily set up in her living room. She also provided a detailed packet with veterinary records, breed information, and notes outlining the training and socialization she had already started.
Finn has been nothing short of exceptional. He is healthy, loving, emotionally and mentally intelligent, and quick to train.
Thank you, Mary, for giving us our forever puppy!

I just wanted to take a moment to express our deepest gratitude to you for Jupiter - our black lab from Chloe’s third litter. He truly is a wonder, in temperament and in smarts.
We were so pleased, when we took him home and he already knew his name and how to sit. Now, at just 11 weeks, he can come, retrieve, lay down and drop it. He’s
I just wanted to take a moment to express our deepest gratitude to you for Jupiter - our black lab from Chloe’s third litter. He truly is a wonder, in temperament and in smarts.
We were so pleased, when we took him home and he already knew his name and how to sit. Now, at just 11 weeks, he can come, retrieve, lay down and drop it. He’s gentle, kind, inquisitive and goofy, plus handsome, too!
I was a little nervous going with a breeder I hadn’t worked with before, but you truly put my mind at ease- opening your heart and home to us so we could meet Jupiter’s mom and dad and see their environment. You knew each dog's personality and helped match us up with a pup that would best fit our lifestyle. It was so evident that you put the welfare of your pups first, and back it up with love and attention.
Our vet also had nothing but praise for Jupiter, and I would highly recommend Marlow Hill Breeders to anyone looking for a wonderful pup to add to their family.
With deep thanks,
Jill Kimball




We got Bruno from Marlow Hill Breeders, and from the first day he’s had a wonderful attitude. He’s very smart for a puppy, not skittish, comfortable with loud noises, and open to new experiences and enrichment. He came into our home with exactly the kind of temperament you hope for in a new dog.

We got Bruno from Marlow Hill Breeders, and from the first day he’s had a wonderful attitude. He’s very smart for a puppy, not skittish, comfortable with loud noises, and open to new experiences and enrichment. He came into our home with exactly the kind of temperament you hope for in a new dog.
When Mary first said she bred for temperament, I didn’t fully understand what that meant. I just knew I wanted a black Lab :) Now I completely get it. Bruno is confident, well-adjusted, and very well behaved for a puppy. He slept through the night by day three and has had no nervousness or attachment issues.
Mary also clearly cares deeply about her dogs. She doesn’t just place puppies and disappear. She follows up, checks in, asks questions, and freely gives advice, which has been so helpful as a first-time dog owner.
We’re so happy we found Marlow Hill Breeders and would highly recommend them to anyone looking for a well-rounded puppy with the right start in life. Tatyana Slyvkin

Hi Mary,

Hi Mary,
I wanted to take a moment to thank you and Marlow Hill Breeders for bringing Thor into our lives.
I have had many dogs throughout my lifetime, and I can honestly say Thor is my favorite. He is incredibly sweet, cuddly, loving, and eager to learn. From the beginning, it was clear that he had been given so much care, attention, and early development before we brought him home.
Thor has been easy to train, affectionate, and such a joy to have as part of our family. I truly believe that reflects the time, love, and detail you put into raising your puppies before they go to their forever homes.
Thank you again for everything you did to give Thor such a wonderful start. We are so grateful for him.
With appreciation,
Melanie Hinds

Our babies are adopted quickly, so reach out to reserve your furever friend or to ask any questions.
Both of the breeds we raise are considered large breed/giant and need room to grow and time spent. Please only consider this decision if you are looking for your Best Friend that meets your needs but also you can meet theirs.
