Reactivity Is Not a Straight Line: What Progress Looks Like at K9U

Many owners of reactive dogs come to K9 University Chicago (K9U) hoping that training will lead to a finish line, a day when the reactivity is gone for good. Courtney Day, K9U’s General Manager, hears that hope often. Her answer is more realistic, and it helps owners know what to expect.

“Reactivity unfortunately is not a linear journey,” she says. In her experience, there is no single point where a dog crosses over and stops reacting for good. As a dog gets comfortable at K9U, more of its personality comes through. Moments of reactivity can still come up along the way, and K9U staff treat those moments as information about what the dog needs.

This article covers what progress looks like for a reactive dog at K9U, why the staff welcome large and reactive dogs that other facilities have turned away, and how K9U decides whether it can help your dog.

What Progress Looks Like for a Reactive Dog

Owners are often surprised by how their dog acts once it feels comfortable at K9U. Some see photos of their dog cuddling with a staff member. Others hand off the leash at drop-off and watch their dog walk in relaxed instead of tense.

Courtney explains that reactivity usually lessens as a dog settles in, but it does not go away completely. Staff stay alert to it even as a dog improves, because the reactivity is still there under the surface.

For owners, this means the goal is steady improvement, with a plan for the moments when reactivity still shows up. Knowing this ahead of time helps owners see a hard day as part of the process. K9U has written about six real reactive dog transformations if you want to see how that progress unfolds week by week.

Why K9U Welcomes Large and Reactive Dogs Other Facilities Turn Away

When Courtney talks about why K9U takes dogs that other places have turned away, she brings up size before behavior. She names Great Danes, Bullmastiffs, and Cane Corsos as examples. Many facilities cannot take dogs that large, whatever their temperament, because of the space and staffing those dogs require.

K9U has about 14,000 square feet of indoor space and about 20,000 square feet outdoors, with separate play sections for large dogs and small dogs. For dogs that are not ready for group play, K9U’s daycare and boarding for reactive dogs uses separate play areas and does not push a dog into interactions it is not ready for.

Courtney says the staff enjoy this work. “We get to love on and cuddle and play with these dogs that otherwise wouldn’t have that service,” she says. In her words, staff are “almost eager to try and crack that shell” with a reactive or intimidating dog.

What Owners of Reactive Dogs Notice on Their First Visit

Owners of reactive dogs often arrive nervous, especially if another facility has turned their dog away before. Courtney has seen this many times. Many of these owners expect the staff to find something wrong with their dog.

What surprises them is how the staff respond. Staff are less cautious around the dog than the owner expects, and several staff members often want to work with the dog. Clients have told Courtney things like, “we’ve never experienced this, people saying I love your dog.”

If your dog has been turned away before, this is what other owners in your position have described after their first visit to K9U.

How K9U Decides Whether It Can Help Your Dog

K9U does not accept every dog automatically, and Courtney is direct about that. She says the only real limit is safety for the staff who handle the dog.

Before a dog starts, staff ask the owner what happened at the last facility and why. Then they tell the owner plainly whether they think K9U can help. Sometimes the honest answer is “let’s see.”

K9U’s free evaluation for daycare and boarding gives staff a closer look at the dog. It includes three parts:

  • A one-on-one assessment of the dog’s body language, comfort level, energy, and signs of anxiety
  • Controlled introductions to well-socialized dogs, so staff can see how the dog plays and communicates
  • Time in different areas of the facility, so staff can see how the dog handles new sounds and spaces

Courtney says many clients come to K9U because another facility promised more than it could deliver, and the dog was the one who dealt with the consequences. In her view, honesty from the start is what builds trust with an owner who has already had a bad experience.

When you talk with any facility about a reactive dog, share what happened before, including what did not work. That history helps the staff give you an honest answer about whether they can help.

What to Do If You Feel Out of Options

Courtney hears from owners who feel they have run out of places to try. When she answers them, she points to what K9U can offer:

  • A team with years of experience in the industry, at a facility that has operated since 1992
  • Connections to rescues
  • A training department that works alongside daycare and boarding

Feeling out of options after one facility says no does not always mean there is nothing left to try. To those owners, Courtney says, “We would love to meet your dog.” Not every dog is easy, and the K9U team has spent years learning what harder cases need. You can contact K9U to ask about an evaluation for your dog.
