How It Works

SmartLeash quickly, safely and automatically locks the leash when your dog tries to run or lunge. SmartLeash  stays locked until your dog releases tension on the leash. There are many distractions when out walking – both for you and  your pet – but SmartLeash is always on guard. A quick click is heard when the leash locks and silently unlocks when tension is released.

All of our leashes have bright yellow reflective tapes – no dangerous ropes! Reflective side panels and a detachable wrist strap add to your safety and comfort.

Your dog should never be allowed to run away from you on a retractable leash. With SmartLeash, she or he can’t.

Thousands of satisfied customers!

Product Story

Joe Ek was walking his parent’s Miniature Dachshund, Gretel, one Minnesota summer afternoon using a traditional retractable leash. When Gretel saw a squirrel she took off, going behind Joe and quickly pulling the leash cord across his calf. He received a serious rope burn he will never forget, from a 9lb dog. Joe thought this is crazy, I had no idea these leashes could be dangerous, and set out to fix the problem inherent in all other retractable leashes: the suddenly running dog.

Years of experimentation ensued, Joe knew the leash had to be safe, reliable and affordable. The SmartLeash you can buy here is the result of thousands of hours of testing, building and retesting. We think all retractable leashes should have an automatic brake but until that day, there’s SmartLeash.

Frequently Asked Questions (FAQs)

How is SmartLeash different from a standard retractable leash?
SmartLeash operates like any other retractable leash until your dog tries to run or bolt from you — then SmartLeash quickly and safely stops the leash from extending farther. A quiet click is heard when the leash activates automatically. SmartLeash stays locked until your pet releases tension on the leash. You can always push the brake button until it clicks to lock or unlock the leash manually, just like a standard retractable leash.

How can I use the automatic brake to bring my dog closer?
If you pull back on the leash by swinging your arm back, the automatic brake will lock, temporarily locking the leash without you touching the brake button. If you do this repeatedly, you can use this feature to bring your dog closer to you. It’s much more convenient than locking and unlocking the leash using the manual (thumb) brake. Try it!

How quickly does SmartLeash automatically react?
It depends how fast your dog tries to run! Generally SmartLeash will stop your dog within about 18 inches, much sooner than most people can react using a standard retractable leash.

After my SmartLeash stops my dog, what should I do?
As long as your dog keeps tension on the leash it will stay locked. When your dog releases the tension, your SmartLeash will instantly and automatically reset itself, ready to activate again. You can keep the leash locked by pushing the thumb button until it clicks.

Will stopping my dog quickly hurt him or her?
SmartLeash stops your dog more quickly than a person can react so your pet doesn’t gain enough speed to become injured. It’s much safer than stopping a standard retractable after the dog has covered some distance and gained speed.

My dog isn’t well trained and he takes off frequently, is SmartLeash appropriate for him?
SmartLeash is not a substitute for proper obedience training but will reinforce that your pet should not try to chase or run without your permission.

Can I use SmartLeash with my puppy?
Yes! Experience with puppies has shown that puppies quickly learn they cannot bolt or run from you on SmartLeash and modify their behavior fairly quickly.

Why do only the medium and large feature the bungee on the end of the leash?
A smaller dog doesn’t generate enough force to extend the bungee so it would serve no purpose. A very small dog will find it more of a nuisance than a help.

My dog likes to hide her toy under the couch and then barks at me to retrieve. Will SmartLeash solve this problem?

Sadly this problem as stumped us as well.

“In all honesty, I don’t usually use retractable leashes since they are very thin leashes and my dogs can be very strong pullers who love to bolt and lunge. That being said, this leash is quite strong enough for my big boys. Moreover, I especially love this leash’s auto break.”

    I love my smart leash. Honey is only 25 lbs but she must be a slow learner because we have groundhogs along our waking path and after 6 months, she still chases after them. You would think she would get it eventually. She did break the first leash but Joe replaced it in 3 days. It is nice that someone honors their guarantee!

    I HIGHLY recommend Smartleash for many reasons. The bungee feature works great, as does the automatic brake. The leash itself is made from more of a “ribbon” than a rope which makes it safer in my opinion. I bought my first smartleash for my first dog who passed away a few years ago and used it again when we got our golden puppy. When it finally broke, I contacted the company and to my surprise they sent me a new one no questions asked. The customer service is over the top, they really make it personal. Well done Smartleash…and continued success!!

    I have a very strong 65 lb Staffordshire Bull Terrier mix who is great on leash, that is until he sees a squirrel. For that reason I love the automatic brake on this leash and I think it’s the bungee that makes it so strong so I don’t have to worry about being caught unaware once he sees that squirrel before I do. Really well designed and I was even more pleased when they provided a replacement for free once a small plastic piece broke. Even without the free replacement I would have purchased this leash again because it’s a favorite.

    Customer service at its best! My dog damaged our new Smart Leash. I asked PPI if it could be repaired. They said that they would rather replace it. After about 10 days I hadn’t received it so I contacted them again. I again got an immediate response stating that they shipped the replacement within two days via priority mail and sent me the tracking number. The new leash showed up two days later. The USPS was responsible for the slow delivery. Needless to say, PPI was very responsive both via their web contact page and through email. They had no responsibility to replace our leash as our dog damaged it. There was nothing wrong with the product yet they still replaced it. This is outstanding customer service. I highly recommend PPI.

    Simply put it is the best leash on the market. You cannot find a better one period. Pet Product Innovations is the Gold Standard in customer service that all companies should strive to achieve unfortunately most are not close.
    When the retract spring failed I was going to buy another one, my wife said why don’t you contact them. Why waste my time I thought. I would most likely get the same song and dance I get from every other company I’ve contacted about a product that had failed, nothing but frustration, anger and no remedy other than buy again.
    So I contacted them and low and be hold no song and dance! Another SmartLeash is on the way!!!!
