Walking the dog

Its a sunny morning on the way to work, turning into Choumert Road there are two people with buggies walking towards me on the pathway. First is a man with his daughter. He is talking to her, pointing stuff out. The second is a grandma with the rainhood over the buggy. As I pass I realise that the granny actually has two yorkshire terriers in her buggy - its a specially designed dog buggy by the look of it. Doesn't it sort of defeat the purpose of walking the dog if they are riding?
