Not for all dogs

Looks really good quality but for an English Springer Spaniel who is constantly twisting and turning the core gets very knotted and is a pain to unravel - it’s also painful when twisted around your hand so gloves are advisable. Carabiner also opened and slipped off on a main road which could have been disastrous. Doesn’t do it for me so sadly another expensive mistake.


Hi Ann, we are sorry to hear you had this experience. We certainly wouldn't expect the carabiner to open as the screw gate feature should guard against this. Please get in touch with our team via to discuss this further. Thanks

strong and durable

my dog pulls a lot (trying to train him) and this leash is really strong. I appreciate the locking carabiner because I know my dog will be safe and wont break free during walks.

Our go-to leash

The grip of this leash is so comfortable, easy to hold and doesn't dig into your hands. The 'rope' leash is super durable and strong. The carabiner clips is functional and easy to put on and take off with the added security of the locking mechanism. All of the parts are put together well and I have no doubt they will continue to hold up over time as we use this multiple times a day with a dog that pulls a bit. We also got the **** bag holder that fits nicely near the handle.
