I thought Valencia was bad. Madrid is worse. Dogs!
The animal seems to be the accessory du jour in this country and they are everywhere, including in the cities. Which is, I imagine, the problem: no owner is game enough to carry a small plastic bag for scooping up they’re friend’s droppings while walking along the Gran Via or Calle Mayor. It’s just not the look!
Thus, be careful here and keep an eye out underfoot. But an Aussie traveller I met in Valencia tells me that Paris tops the lot. He missed half the French capital thanks to dog poo. Such was the cost of his vigilance.
