My Dog Trainer Told Me to Throw Away My Retractable Leash. She Was Right.

The cord was still wrapped around her leg when she walked into the training session.

Not tightly. Margot had unwound it before the burn fully set in. But you could see the pink stripe across her shin above her sock. Her Doodle, Frank, was doing his best to read the room. He was failing. Frank is not a subtle dog.

"Is that from a retractable leash?" her trainer asked.

Margot nodded.

"Okay." She went to a cabinet, pulled out a plain six-foot leash. Nothing fancy. Probably cost eight dollars. She held it out. "Take Frank outside. Walk him for five minutes. Come back and tell me what you feel."

Margot gave me this story six months later. She walked out of the training facility a little annoyed, because she'd spent forty dollars on that retractable leash and liked the idea of giving Frank room to roam. She walked Frank once around the parking lot. Then she stopped.

"I could feel exactly where he was," she told me. "Like, with my hand. Every move he made, I felt it."

She has not touched a retractable leash since.

What a Retractable Leash Is Actually Doing

Retractable leashes are designed around one premise: that your dog should have as much freedom as the mechanism allows. Sounds generous. In practice, it creates a string of problems that don't show up until they do. And when they do, they show up fast.

The cord itself is the first issue. At full extension, a thin braided cord generates enough friction to cut skin in under a second. It's happened to fingers, ankles, and legs. If that cord is between two dogs mid-greeting, it's happened to necks.

The second issue is communication. A 16-foot line with a spring-loaded reel gives your dog almost no information about what you want. And it gives you almost no information about what your dog is about to do. You're not connected. You're just nearby.

The third issue is behavior. Retractable leashes teach dogs to pull. Every time the dog moves forward and the reel extends, the dog learns that pulling forward opens up more space. You're not training loose-leash walking. You're training the dog to drag you toward things.

Let's be honest. Most of us figured this out the hard way.

So What Should You Actually Be Using?

This depends entirely on one question, and it's the only question worth asking: What is this leash for?

For daily walks in a neighborhood or park: A standard 4 to 6 foot leash. It gives you control, connection, and the ability to communicate through the line. Length and handle comfort matter more than anything else. Get the length right for your dog and your walking style, and the rest falls into place.

For training sessions: Same 4 to 6 foot range. Pay attention to weight. A heavier leash creates more feedback for the dog. A lighter leash requires more precision from you. Most trainers working on loose-leash skills prefer something with a little substance to it.

For running or walking multiple dogs: I run with my hands-free heavy duty leash around my waist and it changes everything. No grip fatigue, no leash swap mid-stride, no face-plant when the dog decides right now is the moment. I also use it when I walk two dogs at once. One dog on the hands-free around my waist, the other on a standard six-foot leash in my hand. That setup gives me full control of both dogs and a free hand for my phone, a coffee, or whatever else the morning requires. It's that simple.

For small dogs: Length matters more than you'd think. A 6-foot leash on a 12-pound dog can still give too much slack in tight spaces. A 4-foot leash gives you precision without feeling restrictive.

The Leash Is Not Passive Equipment

I think the reason most people default to retractable leashes is that they feel generous. You're giving the dog freedom. You're not being controlling. And I understand that instinct. I really do.

But a leash isn't a constraint. It's a conversation.

At LUCKY+DOG, every leash we make starts from that premise. The length, the material, the handle weight. All of it is built around what you're actually doing with your dog. Our standard 6-foot leash is the workhorse. Our hands-free heavy duty leash exists because some people actually run with their dogs and need both hands free.


It's all in the nitty gritty details. The ones you don't notice until you've got a cord wrapped around your leg in a parking lot, realizing you've been having the wrong conversation this whole time.

Margot upgraded her setup the week after that training session. Frank has not wrapped a cord around anyone's leg since.

It's that simple.
