Rounding the corner I saw this scene unfold.
The pony is apparently a fallabella originally breed in Argentina from Shetland ponies but now very popular in Ireland. What you might ask are they doing in the inner city of Dublin. This area is a cross section of emigrants and settled travellers. The Irish element love their horses and keep in inner city yards a wide variety of shapes and sizes, Dublin seems to be unique in Western Europe where the working classes aspire to have their own pony's or horses in the city centre. And frequently ride them in the busy urban environment.
