Troy is right, that is the recommended procedure. However. the trap that killed Maggie was a 220 conibear. I have since tried to practice to open just using my hands, but I just don't get it. I also tried using the woven rope, but every second is important and with a struggling dog, I don't know if I can do it in time. It was recommended to carry a small pair of bolt cutters. If you cut through the spring it is an instant release of the trap. I will happily pay for the trap. Even so, there is no guarantee if you get the trap off quick, that the dog will not suffer damage to the trachea, esophagus or the vascular system in the neck.
