Ascending and rappel
Once the rope is in place, the best way to ascend is by using blocking mechanic apparatuses. These are able to slide upwards and block themselves when the rope is pulled on downwards. The guide can go up the rope with a blocker making it run alternatively as he wishes. The blocking device, which will be located on the person's chest, will be directly attached to a waist harness while the second one will be situated further up and a stirrup will be tied onto it. The blocking device joins the chest harness to the waist, meaning that the weight will fall on the anchorage points of the latter. A security rope will be on the harness and another longer one will serve as a pedal so as to maintain the weight with your legs; be careful to not pull excessively with your hands. Keep in mind that in certain types of situations such as when in water or working with ice, mechanic blocking devices are more useful. To be able to descend over the rope in a controlled manner and stand, you will need to use a rappel that will be attached to the waist harness. There are certain types of rappels that allow the person to stand without having to manipulate it (these automatically break or slow down the descent considerably); this allows the person to be able to at the same time have his hands free, and this is very handy especially in the case of someone who is working with a dog. Allowing a dog to climb these areas might be dangerous since the dog could have an accident and it is unnecessary to expose the dog to this type of danger, besides this, the dog will also use up a lot of its energy climbing. It would be better if the guide himself were the one that transports and carries the dog up on his back with the required canine harness. To abseil the dog you will need to use the dog harness on your waist in the safest place possible depending on what the circumstances are.
