Leash Reactivity Training Class

The Average Leash Reactivity Class
Leash reactivity is the number one behavior problem for dogs in Chicago. You will find various group classes and memberships in the area focused on leash reactivity, but we do things differently here.
In the average “leash reactivity group class,” all of the dogs are put in a classroom with visual barriers (opaque fences) in between them. They learn some training skills and then very slowly are exposed to a “demo dog” popping into their view and moving away. Typically, some progress is made in the classroom, and everything falls apart on neighborhood walks. The training plan moves too slowly, and the owner and dog are left struggling.
The Rehearsal Issue
Every time a dog lunges and barks on the leash, the habit of leash reactivity is further solidified. Leash reactivity training needs to move as fast as possible so that these events can be stopped.
Management and Distance
Typical leash reactivity training programs tell you to avoid the problem while you work on training. While this is sound advice, it is not practical for most dog owners in Chicago. Dogs are everywhere! When working on leash reactivity in the city, an aggressive and consistent training plan is needed to get the training dog working comfortably around other dogs as soon as possible.
A Group of All-Reactive Dogs
A group of all-reactive dogs together in one room is a bad vibe. Even if they can’t see each other, the dogs know that other dogs are there. Stress hormones fill the room. Some dogs feel trapped because they are indoors. Dogs hear each other whine and bark, and it echoes off the walls. It’s difficult to take breaks because you are trapped in a maze of visual barriers. This is no fun!
The Solution
Instead of integrating reactive dogs into group class by putting them with a group of other reactive dogs, I mix my recovering leash reactivity cases into my regular group classes – usually starting with my outdoor class Teamwork on the Town. The more experienced students in my classes act as positive role models for the new students, showing them how to be well-behaved.
Working outdoors allows dogs to take breaks and regulate naturally by sniffing, exploring, and stretching their legs – something that is not possible in small indoor classes.
Foundations
Most students need help first with foundational training skills (basic obedience, leash handling skills, etc.) and a group setting is not an appropriate environment to teach those skills for a dog with leash reactivity. At least 1 private lesson is required before joining group class. Click here to read more about private lessons.

The V&MK9 Promise
The Venus and Mars K9 difference is that dogs prone to leash reactivity are not treated like freaks or weirdos and kept in separate classes for the rest of their lives. Some dog trainers might try to convince you that you need to keep buying special courses for reactivity, or stay in special support groups indefinitely. While it is true that some dogs’ temperaments fundamentally make for a challenging training puzzle, it is also true that many trainers will make you feel like your dog is worse than they actually are – either because the trainer lacks skill, or because this is a business scheme to take more of your money.
Even if your dog’s reactivity is not 100% “solved” yet, we strive to integrate them into “normal” life as soon as possible – while of course ensuring that you and your dog are healthy, happy, and not overwhelmed. Please reach out if you have any questions about this system!
Why Does Leash Reactivity Happen?
"Leash reactivity" refers to a range of behaviors that mainly occur when your dog is on a leash. These behaviors might include freezing, pulling, whining, growling, lunging, barking, or snapping. The following are excerpts from my full guide about leash reactivity.
Leash Reactivity Causes and Training Plan:
Many things can be going on for a leash reactive dog: Play solicitation Demand barking at the dog for attention Frustration Predation Invitation to fight Fear Defensiveness Space seeking Surprise or startling Alarming/alerting Guarding territory Guarding handler And more… All of these feelings or intentions are augmented by the restraint of the leash. And don’t forget that a dog can be thinking and feeling multiple things at the same time, just like you or I can. In much of dog training, I am interested in assessing a behavioral sequence to analyze why the dog behaves a certain way, in order to create the best plan for changing that behavior. Leash reactivity cases tend to be quite different in this regard, for a few reasons. Generally, the behavior is cranked up so high that the primary thing that is going on is that the dog is simply freaking out. In other words, regardless of what the dog was initially thinking when they first started to display leash reactive behavior, there’s a good chance that they don’t know what their initial intention even was anymore. The leash reactivity is detached from real world happenings. When I say that leash reactive behavior is detached from real world happenings, I mean that most of my client dogs will start our lesson series screaming continuously at a dog who is standing 100 feet away and calmly looking in the other direction. Across many different personality types, you can watch these dogs bark and bark and see that there is not a single damn thought behind those eyes. If they ever thought they were accomplishing something, we have generally passed that point by the time the dog comes in for training. Why does this happen, you ask? I think of this situation in 2 ways: The leash reactive behavior is “intrinsically rewarding,” meaning that it taps into dogs’ little doggy brain instincts and needs no reinforcement from the environment to get stronger and stronger. For some dogs, it is inherently motivating to freak out - often because we bred them to bark at stuff for various reasons. The sight of another dog has taken on a strong association with stress and excitement. When the training dog sees another dog, the reactivity is simply an expression of emotion.
The Training Plan My overall leash reactivity training plan has 3 phases: Foundations: Train formal skills and proof off of non-trigger distractions (meanwhile, accidental exposure to trigger is as close to 0 as possible) Set ups: Structured exposure to trigger in training set-ups only Real life: Training set-ups blend into real life practice and the training is taken into organic scenarios (which is a spectrum in itself, of course) Formal Skills: Why and How “Formal skills” is also known as obedience or trained behaviors - as in sit-stay, come, heel, etc. In challenging environments, you need a training plan that focuses on formal skills, because they help you give your dog guidance and thus more reliably influence their behavior. Sounds kind of obvious, right? Well, if I may get on a high horse, I frequently come across dogs who have dropped out of training with other trainers for leash reactivity using programs that primarily focus on a classical conditioning approach, meaning they simply pair the sight of other dogs with food.* This will fix the problem in very easy cases that could have done everything themselves at home with Youtube videos alone. Other than for easy dogs, frankly, this training plan sucks. It treats dogs like mice in a science lab instead of animals in a dynamic real world. It does not hold up, and it generally wastes a lot of time. *I like “look at that” in combination with other techniques. The problem is when people pay hundreds of dollars and leave with only LAT. On the other side of the spectrum, it's important to emphasize that skills taught with compulsion as the primary motivator will not effectively address leash reactivity either. I often encounter dogs that have been taught, for example, to heel primarily with an e-collar, and then essentially punished with a high-level stimulation for attempting to react to other dogs. However, these dogs were never given the skills to help them regulate their emotions. As a result, they may sulk past some dogs until they can't handle it anymore, leading to explosive reactions and potentially even more difficulty calming down than before the training program. When I come across either of these archetypes, I mostly restart their training with the below techniques. Sometimes their prior experience allows them to graduate some steps faster than average. Sometimes we are starting from scratch.
Troubleshooting and Extra Credit Leash reactivity can be tied to more global behavior problems that need to be addressed before the training can be considered successful. These concepts can also be the key to taking a leash reactivity routine that feels like a bandaid solution to truly feeling like the “problem” is “solved.” Many of these things have an obvious relationship with one another. Pulling on Leash and Overall Poor Leash Handling Skills A dog who is used to yanking their owner around and pulling towards what they want is going to be more prone to getting frustrated about not being allowed to move toward a dog that they want to get to. Additionally, proper leash handling and being able to forcefully move a training dog away from a problem scenario make a huge difference when episodes of reactivity do happen. Solution: Train leash skills separately from leash reactivity drills. In my experience, leash walking is the skill that having a professional coach you in live time is most helpful for, because it is such a dynamic exercise where it is also so easy to develop bad habits. Gear A dog who is further triggered by the sensation of tightness in their gear (harness, collar) and a dog who has too much physical leverage with their current gear set up is going to have a harder time training for leash reactivity. Solution: I customize gear recommendations for every team I work with. Demanding Behavior A dog who barks at, paws at, jumps on the owner, throws “tantrums” etc., to get what they want frequently throughout the day is more likely to generalize that obnoxious behavior towards seeing another dog on leash. Solution: My exact training plan is going to differ from dog to dog, situation to situation. You definitely don’t want to reward these behaviors if they are causing problems, but the training sometimes also requires a well-timed interruptor or punishment to be effective. Overall Life Structure Does your dog instantly get every single thing that they want all day every day besides access to another dog that they see on leash? That could be a problem! Solution: Practice confinement exercises (crates, tethers, baby gates). Practice impulse control such as waiting at doors, waiting for food bowls, waiting to be invited on the couch. Practice structured calm such as place/go to your bed while you do something nearby that your dog would like to be involved in. Conditioned to Ignore Handler and Ignore Cues Picture this: You routinely talk to your dog or try to give your dog a command, without success, and now they think your voice is irrelevant and inconsequential. A new person or trainer takes a dog, and the dog magically responds, and this is the simple reason why: The dog is desensitized to the owner’s voice, but not the trainer’s. Solution: Good, thoughtful, and consistent training that is integrated throughout the dog’s entire day. No Motivation to Train Picture this: A dog is overweight with a bowl of untouched kibble on the floor, has access to any toy he could ever want from the toy bin, busts through your door without looking back at you when they go outside, and maybe even goes to daycare or a dog park where they go crazy with other dogs and never once think of a human. Guess what! That dog has little reason to give you the time of day. Maybe you’re their buddy, but they certainly don’t see you as in charge of any executive decisions. Solution: Establish a relationship where your dog does work for the good stuff in their life. The owner becomes the “facilitator” of the dog’s want and needs. General Anxiety, Fear, Confidence Issues A dog who is super uncomfortable in their own skin while outside, jumping at traffic noises and spooking at a bag blowing in the wind is more likely to have trouble with seeing other dogs on leash, as described in the “trigger stacking” section. Solution: I may “prescribe” a variety of confidence boosting exercises such as defensive handler drills (think variations on body blocking), problem solving games as simple as trick training that make the dog feel cool and brave, obstacle work that changes the way the dog uses their body to engage with the environment, and more. Counter-conditioning protocols for other triggers and phobias may be relevant. There are certainly some cases of global anxiety that I refer to a vet behaviorist to discuss treating the anxiety from a medical lens. (Sometimes it is hard for me to make this call upon first meeting a dog, and I often will bring up the subject after knowing them for awhile.) Health and Enrichment Double Disclaimer I said it earlier but I’ll say it again - a clean bill of health and fulfilling a dog’s biological needs are imperative for successful training. Social Skills Greeting, coexisting off leash, and playing with other dogs is sometimes part of our plan - particularly with young dogs and dogs whose confidence has room to grow. We work on “direct” social skills only with “helper dogs” that are trustworthy, socially skilled, and matched to the training dog’s temperament and needs. Click here for my guide on socializing dogs.

Testimonials
Giovanna & Enzo
"I cannot speak highly enough of Cori. We began our journey with 1-on-1 sessions to address my dog's anxiety, reactivity, loose leash walking, and over-excitement. Cori's expertise and dedication were evident from the start.
Under their guidance, my dog's behavior has undergone a remarkable transformation. Cori's approach is both personalized and effective. They encouraged us to participate in group classes, even though I was initially nervous due to my dog's selectiveness with unfamiliar dogs. Cori keeps in mind dogs different skill levels and comfortability by managing distractions and visibility of other dogs.
Cori's genuine care for the success of both my dog and me sets them apart. We've been working with Cori for almost three years, and I wouldn't want to train with anyone else. Cori makes training enjoyable and shows you how to seamlessly incorporate it into everyday tasks.
I trust Cori completely and would follow them anywhere! Whenever I have questions, Cori is always ready to help, breaking down solutions for both me and my dog. I recommend Cori to everyone seeking professional, caring, and effective dog training. Cori truly is the best!"
Michelle & Storm
"Wow, Cori is a dream dog trainer and expert in dog behavior. I started working with them to help my THEN-reactive 5 yr old Doberman pinscher rescue (aptly named Storm) take the first steps to feel more comfortable around other dogs. I think what stands out about Cori’s approach are 3 things: 1) their realism about expectations and possibilities that training can provide, which was different from the dogma (no pun intended) about how “if you didn’t train your dog before age 2 they’re a lost cause” or “this 2 week board and train will solve everything” — Cori saw all the potential and worked to get us there. 2) step by step guides, videos, and feasible “homework” specially tailored for me and Storm to practice and work our way up to our goals. 3) deep understanding of dog behavior — Cori works to tackle root causes and the depth of their experience helps them easily “diagnose” what’s going on in any given situation.
The results over the past year of working with them have been astounding; my friends who knew Storm before ask me HOW DID YOU DO THAT?! Before, Storm couldn’t be within 20-30 ft of another dog without completely losing it. Barking, lunging, and and generally getting out of control - being 85 lbs this was becoming a safety issue. Bit by bit we worked to increase her confidence and build on the tools to actually get her to a place where she can socialize (albeit awkwardly) with other dogs. Cori devised a totally custom strategy for this that included group classes, 1:1’s, 2 week board and train, and calls to discuss homework. Fast forward, Storm now has a couple select dog friends, can even play in the park with other dogs! She still has her quirks and sometimes meets a dog that sets her off, but now we have the actual tools and SKILLS deeply engrained that can help us navigate. I don’t even have to ask her for a “down” when another dog is approaching. Storm does it on her own — because she knows it’s a safe space where she’s confident in herself. That’s the type of behavior change that Cori prioritizes in their work.
Last thing - I recently boarded Storm with Cori and honestly was a little jealous that I couldn’t get in on the fun :P They went on all sorts of adventures and pack walks and Storm came home even more confident around other dogs. Highly recommend all around."
