Jose Manuel Crespo, former mountain climbing instructor, pilgrim, and member of the Asociacion de Amigos del Camino de Santiago de Madrid."Dogs usually will not approach you when they see you carrying a pole or a walking stick. Don't worry if they bark, but they could bite you if they growl. In that event do not hurry on, run, or show fear. Raise your hand holding the stick, and cry out loud: "a casa!" Sometimes they go away. Protect yourself by striking the pole upwards/downwards, so that you have time to repeat your cry. If you get bitten, go to a doctor or pharmacy and afterwrds fill out a report with the nearest Guardia Civil Post."
