About Us

Suburban K9 offers a wide variety of dog training classes, in home training, private training, and our premier dog boot camp.  After our head trainer appeared on Animal Planet, we have had various opportunities to train for high profile clients from all over the country.  Clients routinely send their dogs from out of state, and we work with them to ensure a seamless training experience.  Our mission is to modify negative behavior which may lessen the enjoyment you get from your dog and impact your quality of life together. Matt and the other trainers instruct owners using methods that have been in development at Suburban K9 for close to a decade.  Our method is like no other and allows us to help both dogs and clients quickly.  Our method is specifically designed to be easy to apply so that clients get the best possible results with the lowest upfront training cost.  We focus on two main goals with our training.  We teach dogs to be respectful and calm.  When clients call us asking for help, invariably the issue is one of either respect or calmness and our trainers are experts at identifying which approach to use in each situation.

While we train for a variety of reasons, our main purpose is helping clients and their dogs enjoy their lives together.  Many of our clients have rambunctious dogs that make life stressful for both dog and human.  Some of our clients have dogs with severe issues such as fear.  Our trainers are experts at rehabilitating fearful dogs and helping them regain a balanced and calm state of mind.  The improved state of mind helps the dogs become more social with people and other dogs.  All of our trainers gained experience working with rescue dogs from a variety of organizations in order to become proficient in handling all issues.  We feel very fortunate that our training is so well regarded in the dog community that we are able to help other dog trainers, boarding facilities, animal communicators, dog rescue groups, and veterinarians with dogs that they are having issues with. We have even been called in from time to time to help out champion show dogs that are starting to develop behavioral issues both in and out of the ring.  Our trainers are very proud of the fact that so many local veterinarians refer us to their customers when their dogs need a little extra help.

Our dedication to ensuring every dog gets a chance at their best life has led to our special relationship with the West Suburban Humane Society.  We provide specialized training for dogs in their care to assist with preparing these dogs to be successfully placed in “forever homes.”Additionally, we donate time to train the staff and volunteers at West Suburban Humane Society to help ensure the dogs in their care are handled properly every day. Some of the other animal rescue groups that we have had the privilege of working with include:

• Almost Home Foundation
• Animal Rescue Foundation (A.R.F.)
• Animals Deserving Of Proper Treatment (A.D.O.P.T.)
• Shih Tzu Rescue, Adoption, and Education Safehouse (S.T.R.A.E.S.)
• New Beginnings Shih Tzu Rescue
• H.E.L.P
• Illinois Animal Rescue
• Illinois Doberman Rescue
• Romeoville Humane Society
• Second City Canine Rescue

Matt Covey

Having grown up in a family that spent their time breeding and showing dogs, it was only natural that Matt’s long time passion for dogs turned into his profession.  Matt’s training skills have given him the opportunity to train for celebrities such as Antonio Davis of the Chicago Bulls and Bobby Simmons of the Milwaukee Bucks.  Matt’s reputation recently allowed him the incredible opportunity to work as the head dog trainer for a new series on Animal Planet.  The pilot episode went well so hopefully you will be seeing him on television soon.  When Matt isn’t busy training dogs or spending time with his family he managed to squeeze in the time to earn a law degree from Northwestern University.  Matt also writes and edits dog behavior articles for various newsletters and websites.
