Gosh sounds like it's all very uncomfortable just taking your dog for a walk! A lot of people are scared of dogs, my mum is phobic of them. There's been a lot of publicity the last year in England about dogs that attack as well. But this cultural aspect is interesting...
I notice a difference in parts of the country with attitude towards dogs and dog walkers. In London, all the dogs are on leads mostly, and people are more scared of them. The chav's have their pit bulls, staffs etc. off lead and it's used as part of an intimidation act. Up north, everyone has dogs and I go to the park just to watch them all running around, sniffing each others butts (the dogs this is), flopping their ears and wagging their tails and they look so happy! In London I seem to see more dogs being yanked away & pulled along! But there is more greenery up here, than in London. When I was down South in Cornwall, there were so many dogs I saw a day, and each i saw was a compeletely different breed- from huskies, to cross bred wolves, to sausage dogs! And all the owners were really friendly, and everyone seemed to go and have a chat with the owner and to pet the dog.
I guess London shows it's stiff upper lip and unfriendly attitude even when it comes to walking dogs.
