Meet Corey Rosier

Owner of The Modern K9

Founded in 2018, The Modern K9 was built on a simple principle: to facilitate communication between dog and owner in an effective and ethical manner. At the center of that mission is Corey Rosier, whose diverse background and relentless pursuit of knowledge have earned him a reputation for producing real, lasting results for both working dogs and family companions.

More About Corey

A Higher Standard of Care for Your Dog

While we are the best in the business in changing behavior and building relationships. We also pamper your dog while they are with us. Each dog gets a complimentary grooming package when they are here. We will bathe, blow out, brush, and trim your dog’s nails (if needed).

20 acres of fields, woods, and trails for your dog to enjoy.

Family-Owned Dog Training With a Personal Touch

We are a family owned and operated dog training business located in central Maryland. We specialize in training companion pet dogs as well as sport dogs and police k9s.

The Modern K9 was founded in 2018 and since then we have helped hundreds of dogs and puppies through our specialized, board and train programs as well as private lessons. Our expert training programs are custom tailored to your dogs needs. Whether your dog is dealing with reactivity, separation anxiety, or just a young rambunctious dog who needs a little structure, we have a program for you. Any age or breed, on leash or off, we can help!

Your dog will stay in our home with our family. We do not utilize kennel buildings or leave your dogs at a facility. This allows us much more time to work with your dog because we are not limited to an 8 hour workday at which point the trainer goes home until the next morning. Your dog will be with us night and day. We are fully insured and practice stringent safety measures. We pride ourselves in not having dog fights, disease or accidents. Your dog is our number one priority.

We guarantee your dogs success! Reach out today to schedule a free consultation to begin working with the best dog trainers in Maryland!
