As a bicyclist, I discovered a very cheap but effective means of deterring dog attacks. a mixture of 2 parts water and one part ammonia in a spray bottle works wonders! As the dog runs through the mist, it suddenly gets very uninterested in pursuing you. The small amount of the mixture spray is not enough to cause any damage to the animal, but just enough to cause it to have a sneezing fit for about ten seconds.
