The classical retractable leash can be very dangerous for humans and dogs a like. A lot of the dangers don't have to with handling it the right way, but they come through situations you as a handler can not control.
I just read in another forum of a young lady accidentally amputating the first phalanx of a finger because of a flexi leash.
- they can lead to ugly cuts and burns when humans grasping the leash in reflex
-they're not easily seen in the dark which can lead to people falling over the leash or runing into it and hurting themself and the dog
- the stop button sometimes stops working and can lead to the dog running on the street: dog dead.
-when the leash spool slips out of your hand you can hit the dog with it and it gets hurt
- sudden contact with other dog, can lead to other dogs getting hurt
- a stronger dog can easily snap the cord, which is not very insecure and can lead to dog running away or infdront of a car
-the dog can get tangled up and the leascuts them
-everytime the leash is in tension and you push the stop button and make the dog stop suddenly it can hurt the dogs neck and/or spine.
Such a leash also doesn't help with leashtraining too
-the dog does learn that it is normal that there is tension on the leash, which incourages leash pulling
-the dog can not estimate how long the leash is until they get stopped forcefully
Yes, of course you can also hurt yourself and others with another leash, but because the Flexi gives even more opportunities to hurt others or yourself or a dog, please think about it carefully before buying and using a Flexi leash.
