Are Retractable Leashes Really THAT Dangerous? Yes, They Are & Here’s Why

Are Retractable Leashes Dangerous?

Retractable leashes often pose more risks than traditional ones, and many pet owners may not realize just how dangerous they can be. For those asking, "Why are retractable leashes dangerous?" the answer lies in the sheer number of injuries they’ve caused. On one side, you have dog owners who love the extra 30 feet of freedom these leashes offer their pets. On the other, critics view them as accidents waiting to happen—tools of chaos that can harm both pets and humans alike.

 

The debate between retractable leash opponents and proponents is a heated one among dog owners. Critics argue that allowing a dog to roam 30 feet away on what they see as a “retractable weapon” is simply inviting disaster. On the other hand, supporters of retractable leashes believe it’s unfair to condemn a product solely because of misuse or human error. When used responsibly, they assert, these leashes can be perfectly safe. Proper use requires common sense, attentiveness, and an understanding of the leash's limitations. While retractable leashes aren't suitable for every situation, the ongoing debate highlights the strong opinions among dog owners about whether these tools are helpful or hazardous.

What Is A Retractable Leash?

A retractable leash is a dog leash designed with a thin, durable cord coiled inside a spring-loaded mechanism housed in a handheld plastic handle. This leash allows you to adjust its length, giving your dog the freedom to explore at varying distances. Equipped with a convenient locking feature, you can easily control and set the leash to your desired length. When unlocked, the cord extends freely until you lock it to stop further extension or retraction, ensuring optimal control during walks. 

Pros: Why Some Like Retractable Leashes

When used correctly, retractable leashes allow well-trained dogs to explore up to 20 to 30 feet away from their owner. This gives them the chance to happily sniff around new scents and investigate their surroundings, all while enjoying a sense of freedom. Advocates of retractable leashes argue that these tools strike the perfect balance—offering dogs a taste of adventure without exposing them to the serious risks faced by those who roam freely.

Cons: Why Retractable Leashes Are Bad

The drawbacks of retractable leashes often stem from human error, including poor judgment, inattention, or misuse. Regardless of how well-trained your dog may be, the risks associated with these leashes usually arise from the handler's lack of awareness, not the dog at the other end. Unfortunately, mishaps can be severe — such as fingers getting injured or amputated when tangled in the leash. Retractable leashes are particularly unsuitable for crowded, urban, or confined environments. Here’s why:

  • City Streets: Managing your dog from 30 feet away in a busy urban area can be nearly impossible. Picture the narrow sidewalks of Greenwich Village in New York City on a bustling weekend — dodging umbrellas, oversized bags, and rushing pedestrians is hard enough without the added chaos of a wandering dog. In such environments, a playful Lab on a retractable leash could cause serious disruptions or accidents. And when it comes to crowded spaces like subway stations? Retractable leashes are a no-go!
  • Confined Spaces: Take the vet’s office, for example. Retractable leashes can be a recipe for disaster in tight areas. Imagine this recent scenario: A woman at my front desk was reviewing her dog’s discharge instructions, barely paying attention to her pet. Meanwhile, her aggressive dog, attached to a retractable leash, wandered behind the reception desk and began intimidating my receptionist. Panicked, the woman yanked the leash to pull her dog back, startling him and causing him to growl and snarl. It was a tense, unsettling moment for everyone involved.

Stories like these are far too common in veterinary practices. These incidents highlight why some vet offices and pet stores have embraced friendly yet firm policies, with signs that read, “No Retractable Leashes, Please.” Prioritizing safety over convenience helps prevent accidents and avoids unnecessary legal issues. It’s a small step that ensures a more controlled and secure environment for everyone.

Trauma to People

One concern is retractable leash injuries. There is a warning right on the handle to take caution with your fingers. Fingers have been amputated when entangled in these leashes. Humans have suffered serious rope burns and deep gashes as well. Not only can the person holding the leash get injured, but also people in the path of the long cord can get badly hurt or knocked over. Dog fights are also more likely, and pet parents trying to break up a fight is dangerous enough without a retractable leash cord involved. We have all met another dog on a leash while walking our dog and done the funny figure-8-untangle-our-pooches game. This becomes much more nefarious when a retractable leash is involved.

Trauma to Dogs

Retractable leashes can wrap around a dog’s leg and cause much more serious injury than a traditional leash. One of the dangers of retractable leashes is that if you try to retract the leash, the leash naturally becomes tighter around the victim. Clearly, with less control over your dog at a 30-foot distance, dogs have been known to wander into the street and get hit. But there’s another problem with these leashes. If your dog is running or heading toward danger, you naturally try to retract that leash as quickly as possible. Jerking your dog back forcefully to avoid a traffic accident can also cause severe injury to the dog’s neck or back. Recently, a dog’s trachea was ripped open — not by the vehicle that hit it, but by the intense jolt of the retractable leash when the caretaker tried to pull the dog back from the street.

Behavioral Problems

Many behaviorists believe retractable leashes encourage pulling and not listening to commands, the antithesis of what leash training is all about. If you lose total control and drop the leash, the dog can get spooked as if it’s being chased by something. The dragging handle thumps behind the dog causing fear or panic. A dog ran up the stairs of an apartment building with the leash trailing behind it, through an open door to the roof, and plummeted off the roof.

Walk The Walk: Final Thoughts On Retractable Leashes

These leashes present a unique problem to me. Many people don’t seem to have total control of their dog when using one. “The button. The button. Use the button,” I hear myself saying in my waiting room. There is a learning curve with this product. It’s as if you should be licensed before operating! Practice using it in a safe, unpopulated area. Folks who think it’s ridiculous to consider regulating or warning people about these leashes are just not owning up to how easily distracted people can get in this modern world of ours and how that can make retractable leashes dangerous. When you are multitasking, and one of those tasks is holding your husky on a retractable leash, the odds go up on the mayhem-may-happen meter. Picture this: Your dog and your kids pile out of your car in a parking lot at the same time, and White Fang runs the extra 20 or 30 feet on his retractable leash because he thought that piece of blowing trash was a cat. Then your cellphone rings while you’re trying to lock your leash, but White Fang has already entangled himself around a shopping cart.


Life happens while we’re thinking of something else. We are all only human. Be extra careful and mindful when using a retractable leash.
