This involves placing our hand (palm facing our dog) between our dog and the object or source of the disturbance. Since our dogs communicate mainly with body language, they learn anything visual very easily. This signal is easy to do and possible to do as often is needed in most situations.
We observed that the hand signal has a dog physiological impact on the dog. It permits the pulse to stan-by or decrease in case of a threatning situation because the hand signal is a neutral, universal language and non invasive gesture you can do towards the dog in different situations.
