SmartLeash® is the FIRST and ONLY retractable leash that automatically stops your dog when he or she tries to suddenly run or lunge. SmartLeash operates like a regular retractable leash unless your dog tries to run -- then Smartleash locks, quickly, safely and automatically. Like a seatbelt! It stays locked as long as your dog has tension on the leash. When your dog releases tension, SmartLeash resets instantly, ready to protect your pet again.

SmartLeash features a bright yellow reflective tape so others can see you and your dog, a comfortable rubberized grip and a convenient push-button manual brake. Every leash comes with a removable reflective wrist strap for added security. Medium and Large models have a high-strength bungee attached to the clasp to absorb the normal stresses associated with walking your dog when the leash is locked.  

Medium - up to 28lbs

Large- up to 50lbs

Once you try SmartLeash you'll never use another retractable leash again!
