TESTIMONIALS

Deer Creek Mastiffs are producing the highest level of mastiff. My family watched for two years patiently waiting and watching litter after litter and testimony after testimony finally my family was ready to purchase a puppy. We finally agreed and picked Rex who is now Bear from the beautiful Brutus litter. Bear is such a good boy he has found his place in our family. Bear has such a calm presence about him he is already sitting on command at 9 weeks and is so eager to learn. I recommend Deer creek mastiff 100 percent.

Working with Deer Creek Mastiffs has been an exceptional experience from start to finish. Their breeding program is built on the highest standards of health, conformation, and temperament, ensuring that each puppy is a true representation of the breed. Communication throughout the entire process was outstanding. From the initial application through homecoming, every step was clear, organized, and supported with timely updates and helpful information. What truly sets Deer Creek Mastiffs apart is their commitment to their dogs for life. They provide comprehensive education for new owners on the unique needs of giant breeds, including nutrition, growth management, and preventive care. This level of preparation gives families the confidence to provide the best possible home. The support does not stop when the puppy leaves their care. Katie remains a trusted resource for questions, guidance, and reassurance for years after homecoming. Her dedication to both the dogs and their owners is unmatched. If you are looking for a breeder who combines expertise, integrity, and lifelong commitment, Deer Creek Mastiffs is truly exceptional.

I wish I could give 6 stars. We took our time and did our research when selecting a breeder. We wanted to ensure they were responsible and kept quality, health and temperament as priorities. I’m so happy we found DCM! Katie was a pleasure to work with, answered all of our questions, and kept us informed while on the wait list. We adore our Sheila x Cletus pup! He is a clear reflection of the work and care DCM puts into the breeding program.

We were looking for a while for a female companion for our 2 year old female English Mastiff and came across Deer Creek Mastiffs online. From the initial contact with Katie, she was amazing. Informative, responsive, patient, and really helped guide us through the adoption and delivery process. Everything I saw online about them was positive. Their website was professional and updated. The pricing was transparent as well as having multiple payment options. I would highly recommend Deer Creek Mastiffs to anyone looking to adopt one of these amazing animals!

Katie was quick to answer all of my questions and is a very sweet good hearted person. Katie is very trustworthy too. She worked with me for several months in helping me pick my dream puppy. And I’m very happy with my puppy i now have, she’s absolutely perfect. And i will most likely be getting another one from Katie in the near future.

We looked for our Mastiff puppy for many months before stumbling across Deer Crek Mastiffs. This was by far, the most detail oriented, up front and trustworthy breeder we came across. After our first conversation, we were confident this is where we would find our next pup. We loved them so much, we left with two! Thank you for allowing us to adopt our beautiful girls.

Katie & Deer Creek Mastiffs we’re nothing short of amazing to deal with from start to finish! Upon my first call to her, we had an awesome conversation in which she helped me to choose Deer Creek, after I had spoke with numerous other breeders, we felt an immediate connection with Katie, you could just tell how much she cares about her puppies! We got Junior last summer when he was nine weeks old, and he has been outstanding since day one! Almost to the point where I remember telling my girlfriend who had never had a puppy, that he was remarkable, because most puppies are not like him! This has continued as he is growing into an adult now, still with the puppy side, very playful and loving, but he has done incredible with his training, he is now fully off leash, walking around, we have had him everywhere from the mall, Home Depot, Lowe’s, Bass pro shop, Publix grocery store, restaurants, everywhere! Haha and all while he is almost 200 pounds and off the leash. Our trainer said that if we wanted to get him serviced, we would be able to do so with no problem even though he’s only still a puppy, because of how well behaved & obedient he is! Katie and I keep in touch regularly as she checks in to see how he’s doing, which is really really nice! If you are looking for a mastiff, look no further than Deer Creek!

Katie was so great to work with in helping me find the perfect puppy. I waited through several litters to get the little dude I had been dreaming of. Katie was always very patient with me, super communicative and responsive. And I can’t say enough about our dog, he is beautiful, smart, loving, and just an all-around great example of the Mastiff breed, really everything we wanted.

Katie was so great to work with in helping me find the perfect puppy. I waited through several litters to get the little dude I had been dreaming of. Katie was always very patient with me, super communicative and responsive. And I can’t say enough about our dog, he is beautiful, smart, loving, and just an all-around great example of the Mastiff breed, really everything we wanted.

We looked for our Mastiff puppy for many months before stumbling across Deer Crek Mastiffs. This was by far, the most detail oriented, up front and trustworthy breeder we came across. After our first conversation, we were confident this is where we would find our next pup. We loved them so much, we left with two! Thank you for allowing us to adopt our beautiful girls.

Katie & Deer Creek Mastiffs we’re nothing short of amazing to deal with from start to finish! Upon my first call to her, we had an awesome conversation in which she helped me to choose Deer Creek, after I had spoke with numerous other breeders, we felt an immediate connection with Katie, you could just tell how much she cares about her puppies! We got Junior last summer when he was nine weeks old, and he has been outstanding since day one! Almost to the point where I remember telling my girlfriend who had never had a puppy, that he was remarkable, because most puppies are not like him! This has continued as he is growing into an adult now, still with the puppy side, very playful and loving, but he has done incredible with his training, he is now fully off leash, walking around, we have had him everywhere from the mall, Home Depot, Lowe’s, Bass pro shop, Publix grocery store, restaurants, everywhere! Haha and all while he is almost 200 pounds and off the leash. Our trainer said that if we wanted to get him serviced, we would be able to do so with no problem even though he’s only still a puppy, because of how well behaved & obedient he is! Katie and I keep in touch regularly as she checks in to see how he’s doing, which is really really nice! If you are looking for a mastiff, look no further than Deer Creek!

Puppy adoption was a great experience and we are absolutely in love with our boy. Beautiful mastiff that’s well tempered. Breeder was very knowledge and went above and beyond with food recommendations, vitamins, etc. I would highly recommend and if we decide to get another we will definitely be going through them.

Our beloved Olive’s (formerly Candy) first birthday is around the corner, and I just wanted to share what an amazing experience we had. I would recommend Deer Creek to anyone looking for an English Mastiff. Nothing but happy, healthy, well socialized puppies here! Ours has helped us foster over 20 dogs of various sizes and breeds since we brought her home, and she makes best friends with all of them. She is so patient, sweet, gentle, and intelligent. Words can’t really describe it, you really just have to wrap your arms around her and let her smush you. Thank you again so much! From 34 pounds to over 150 now, it’s been a memorable adventure our family will cherish forever. We’ll see you when it’s time for our next pup!

My husband came across the Deer Creek website while looking for a mastiff breeder close to our home (NJ). We lost both of our senior English Mastiffs in the past year, and were ready for another. We were very impressed by the website, the positive reviews, and the absolutely beautiful pups we saw photos of. I reached out to Katie and got an immediate response. She was full of information and never made me feel like I was asking too many questions. We took the ride up and decided on our girl, Minnie. Katie was very friendly, very professional with all of her paperwork, and made sure to send us home with food, a blanket, a toy and other goodies to make Minnie feel comfortable in her transition. We can't thank her enough for the wonderful experience and highly recommend to anyone looking for an English Mastiff puppy!
