The Hidden Dangers of Retractable Leashes

As a lifelong pet caregiver and a certified professional pet sitter of over 20 years, I have tried and used just about every type of leash out there. There is one that I absolutely advise people NOT to use and there are many reasons for that. That is the "popular" retractable leash.

While I completely understand the appeal and theory behind them, my experience has taught me different. While the majority of pet owners use them for dogs, it is important to note that they are also used for cats, ferrets, rabbits, and other animals, too. Regardless of the type of pet you have, these leashes pose a potentially serious threat to both the owner/caregiver and the pet!

Retractable leashes are a common sight in pet stores and on sidewalks, promising freedom for pets and convenience for owners. At first glance, they seem like the perfect solution: your pet can explore at their own pace while still technically being “on leash.” However, many veterinarians, trainers, and experienced pet owners warn against their use — and for good reason. Behind the promise of flexibility lies a host of risks that can endanger both pets and people.

1. Risk of Injury to Pets

Retractable leashes can extend 10–30 feet, giving dogs far more range than a traditional leash. While this may sound great, it means:

• Sudden stops can cause neck injuries. If your dog hits the end of the line at full speed, the jolt can damage their trachea or spine.
• Tangled cords can cause cuts or burns. Dogs that wrap themselves in the thin cord risk painful rope burns or serious injuries if they struggle.
• Increased risk of accidents. With so much freedom, dogs can dart into traffic, approach aggressive animals, or eat something dangerous before the owner can react.

2. Risk of Injury to Humans

It’s not just pets at risk — retractable leashes have injured countless owners as well. I can't tell you how many people I know of that have had serious injuries from these leashes! Especially in situations that require quick reflexes and immediate action!

• Finger amputations and burns. If the cord wraps around a finger or hand during a sudden pull, it can slice deep into skin or even break bones.
• Falls and trips. Long cords stretched across sidewalks can trip other pedestrians, cyclists, or even the owner.
• Lack of control in emergencies. When a dog lunges at another animal or person, the thin handle and braking system are no match for a strong, determined pull.

3. Behavioral Issues

Trainers often discourage retractable leashes because they undermine important leash manners.

• Encourages pulling. Dogs(and other pets) learn that pulling gives them more freedom, which makes them harder to manage on standard leashes.
• Reduces owner leadership. Instead of walking with their person, dogs end up in charge of the walk, which can reinforce unwanted behaviors.
• Startles or threatens others. Not everyone wants a strange dog rushing up to them — retractable leashes make it nearly impossible to prevent.

4. Durability Problems

Retractable leashes are often made with thin cords or flimsy mechanisms. These can:

• Snap under pressure from large or strong dogs.
• Break down over time, leaving pet owners with a false sense of security.
• Fail at the worst possible time — when quick control is most needed.

5. Safer Alternatives

For the safety of your pet and yourself, consider these alternatives:

• Standard fixed-length leashes (4–6 feet). These give enough freedom for exploration while keeping your dog under control.
• Long-line training leads. For dogs that need more range (like in parks or open fields), a 15–30 foot training lead is safer, sturdier, and offers more control.
• Harnesses. Pairing a sturdy leash with a properly fitted harness reduces strain on your dog’s neck and gives you better handling.

Final Thoughts

Retractable leashes may seem convenient, but they come with hidden dangers that far outweigh the benefits. From serious injuries to compromised training, they put both pets and owners at risk. A sturdy, fixed-length leash paired with consistent training is the safest way to ensure enjoyable, stress-free walks.

When it comes to your dog’s safety — and your own — it’s better to skip the retractable leash.

I always advise my clients, family and friends to stick with a fixed length leash of leather, web/woven material, or even braided rope and ALWAYS check the condition prior to taking your pet for a walk! Replace leashes that may be worn, frayed, or chewed. Your pet's safety depends on it.
