We went to Devon last Summer, and there were dog free zones, and do friendly zones, on beaches. Made perfect sense.
It is true that people who come from countries were packs of street dogs roam the streets, often starving and therefore aggressive in the search of food (understandably) and often carriers of diseases, worms and even rabies - have grown up fearing dogs and are often terrified of them. But that also applies to lots of people born and bred here.
kircubbin- in a dog free zone, the whole point is that there would be no dogs to jump on you, friendly or otherwise.
