Welcome to Deer Creek Mastiffs

My life revolves around our dogs. They are always by our side whether it be hanging out on the couch, playing in the yard, going for a hike, working in the garage, taking care of our farm animals, they love to be right with us! Our dogs also enjoy going on car rides and they love when we have visitors. We have a 5 year old son who loves our dogs and puppies. All of our dogs are super gentle with him and he loves to give them treats. Our son Hunter loves to pet our dogs and feed them treats. He also enjoys bouncing around on their giant dog beds with them.

Our dogs are happy, healthy, and well loved. Located in Southern York County PA.

“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!”
