I suppose different cultures and countries have different views on things.
My American friend came to stay, and out in the car on her first day, she asked why there were so many dogs being walked along the roads (we are in a rural area) and even in town. I was a bit puzzled, after all, thats what we DO, isn't it? She explained that where she is, you rarely see a dog walking along with its owner!!! This lady has dogs, but has her own fields to run them on. This left me wondering about people who live in towns - what do they do if they do not walk them in the street?
