While we can’t know for sure how dogs feel the carabiner weight, it’s fair to assume smaller dogs benefit from a smaller size, while for larger dogs the weight plays less of a role. All our carabiners are made from aluminum alloy, feature a locking mechanism, and have a breaking load of 400 kg, so they’re all strong and secure.
General advice based on dog weight:
- Up to 10 kg: S size carabiner (screw lock)
- 10+ kg: M or S size carabiner (screw lock)
- 20+ kg: L size carabiner (twist lock) or M size carabiner (screw lock)
Screw lock vs twist lock
- Screw lock: loosen the screw first (if it was locked), then push the gate open, and then tighten the screw again to lock it.
- Twist lock: twist the locking mechanism and push the gate at the same time. It closes automatically and twists back into the locked position when you let go. This can feel tricky if you have any weakness in your hands.
We offer locking carabiners by default for maximum security, but if you’d like a carabiner without a locking mechanism, that’s possible on request.
