Grace has been around dogs throughout her life. In many ways her life is centered around dogs. From training dogs, to relying on Medical Alert Service Dogs for daily tasks, to competing in National Agility competitions, dogs have been teammates, companions and life partners.

Grace’s home pack currently consists of four dogs each with their own special skills and gifts. She trains and competes in agility with her two Miniature Schnauzers Gus and Bernie, who qualified for nationals in his first year of competing! As well as her Standard Poodle, Rafiki, and her Sheltie, Bella, who is a NADAC Champion. Rafiki is also a working Medical Alert Dog and training for Water Fowl retrieval in her spare time.

At K9U Chicago Grace will teach all levels of Agility Training from puppies to competition and will be teaching group obedience training classes. Grace uses only positive training methods and believes in having fun while learning new skills that enhance the bond between dogs and their owners.

When not at K9U Chicago Grace volunteers with shelters and rescue groups in Naperville to help the disabled connect and train service dogs. She also founded Beard & Golden a hand-made custom clothing company providing dog gear and accessories.

Why Our Clients Love Us

K9 University is great. We’ve been going there for 7 and a half years. We’ve done training, we’ve done agility, we’ve done boarding and we’ve done daycare. The only thing we haven’t done is a drop off and pick up. My dog is kind of a nut and they deal with her well.

Debbie W.

I was referred by a previous customer. I had never used a daycare before and my experience has been wonderful since day ONE! The staff is friendly, welcoming and attentive to my dog (and me…LOL)…She loves going there.

Tracee A.

My dog has experienced everything at K9U: daycare, classes and boarding. When he is either picked up by the K9U van or dropped off his tail is wagging like crazy. When I pick him up he is happy to see me, goes outside to relieve himself and then pulls to go back in.

Jane F.

I’ve been a customer for 15 years and counting. K9 helped us raise our puppies and cherish our old girls. I can think of no other place I would trust more with my furry family.

Jonathan A.

This is really awesome dog place. We had a basic obedience training here, and our dog is changed! She listens now, and behaving well, our trainer is really good - she is like a dog whisperer. Love and recommend this place for all dog parents out there.

Yessie S.

K9U is great. They offer classes as well as day camp /sitting services. The size of the location is pretty impressive, as they have a large indoor and outdoor areas for dogs to play. (They even pick up and drop off your dog.). The staff and trainers are very friendly and extremely effective.
