Why is my dog reactive on leash but not off leash?
AVI'S ANSWER
Many dogs are completely fine off leash but become reactive the moment the leash goes on. Part of the reason is that the leash limits a dog's freedom to move, create space, and make its own choices.
But the bigger piece most owners miss is what happens on the other end of the leash.
When we anticipate a problem, tighten our grip, or focus on what might go wrong — our dogs feel it immediately. Over time many dogs begin reacting not just to the other dog or distraction, but to the tension and anxiety surrounding the situation.
The leash doesn't create the reactivity. It reveals it — and sometimes amplifies it.
This is why leash reactivity is often as much about communication and leadership as it is about the dog itself. One of the main things I help owners do is teach their dogs that they don't need to manage every situation on a walk. Through clear communication, structure, and guidance, dogs learn to relax and look to their owners instead of reacting to everything around them.
If your dog is calm off leash but turns into a different dog when the leash goes on — I'd be happy to help you create calmer, more enjoyable walks for both of you.

Why does my dog bark and lunge at other dogs on leash?
AVI'S ANSWER
Dogs bark and lunge on leash for many different reasons — and the bark and the lunge are actually two different conversations happening at the same time.
The bark is communication. Some dogs bark out of excitement and frustration because they want to get to something. Others bark because they're anxious or uncomfortable and are trying to create distance from whatever is stressing them. And some dogs have simply learned that barking works — it moves things away, gets attention, or changes what happens around them.
The question isn't "How do I stop the bark?" The question is "What is the bark trying to say?"
The bark is the symptom. The emotion behind it is the cause.
The lunge is something different altogether.
The lunge is a learned behavior — and for many dogs it has become one of the most effective tools they have.
When a dog lunges at a jogger, cyclist, or skateboarder, that person moves away. When it lunges at another dog, the owner pulls their dog back. Either way the dog has just controlled the entire dynamic of the situation from the end of a leash.
And it works. Every single time it works, the behavior gets stronger.
A balanced dog will ignore the lunge. An insecure reactive dog will lunge back. An aggressive dog will match the intensity and raise it — which only confirms to the lunging dog that the threat was real and the lunge was necessary.
Most owners have almost no control in that moment. The dog lunges, the owner holds on, and the dog is completely running the engagement. The more it practices this, the more ingrained it becomes. The dog isn't misbehaving. It's doing exactly what experience has taught it to do.
The key to breaking this cycle isn't correction in the moment. It's showing the dog — before the moment arrives — that you are managing the situation. That comes through spatial decompression, calm redirection, and approaching triggers with loose leash confidence instead of a tight grip and tense body.
When a dog feels its owner tighten up, it reads that as confirmation that something dangerous is coming. It then does the only thing it knows how to do — try to chase the threat away for both of you.
When you take over the management of the environment, the dog no longer has to.
That's when the lunging stops — not because the dog was corrected out of it, but because the dog finally trusted someone else to handle it.

How do I stop my dog from reacting to other dogs on walks?
AVI's ANSWER:
The biggest mistake people make is thinking they fix reactivity when their dog starts barking and lunging. In reality, you don't fix reactivity in the moment it happens. You fix it with everything that comes before it.
Calm walks start before you ever leave the house. If your dog is bursting through the front door, dragging you down the driveway, and already pulling before you've taken a single step — you're starting the walk in a state of excitement, stress, and disconnection.
The walk is already lost.
The first goal is a calm exit, a loose leash, and a dog that is engaged with you. The human should be controlling the pace, direction, and flow of the walk. If your dog is making all the decisions, you're already a passenger instead of the driver.
Reactivity can come from anxiety, insecurity, frustration, or overstimulation — but the solution starts the same way every time. Clear communication, calm guidance, and helping your dog understand that it doesn't need to manage every situation it encounters.
A reactive dog doesn't need a human riding shotgun.
It needs a human driving the bus.
When dogs trust that their owner is leading the walk and handling the environment — the need to bark, lunge, and overreact often decreases dramatically.

Why does my dog listen inside but ignore me outside?
AVI'S ANSWER
Most people think their dog listens inside but ignores them outside because there are more distractions outdoors. While that's certainly part of it, the real question is — does your dog truly listen inside?
If your dog only responds when a treat is visible, ignores you when something more interesting appears, or struggles to disengage from a window, door, squirrel, or another dog — the issue isn't the environment. The issue is engagement.
A dog that is truly connected to its owner doesn't stop listening the moment the environment becomes interesting. That dog has learned that paying attention to its person is valuable, rewarding, and safe. The goal isn't to compete with every distraction your dog encounters. The goal is to build enough engagement, trust, and communication that your dog naturally wants to stay connected to you.
Treats can absolutely be part of that process — but they should reward good decisions, not bribe a dog that only listens when food is visible.
Communication tools like Look, 1-2-3, Go Find, recall, and calm leash handling help create a real conversation between you and your dog.
These aren't tricks. They're a language.
Used together strategically, they help a dog disengage from distractions, reconnect with its owner, and stay successful even in the most stimulating outdoor environments.
The issue isn't the environment. The issue is engagement.
That's why I spend so much time building engagement before worrying about obedience. You don't build focus outside. You build it inside first — then bring it with you into the real world.
