Dogs blamed for collapsing lampposts
Urinating dogs are being blamed for a rash of collapsing lampposts in Croatia.
A report from the state-run power company says the urine left when male dogs mark their territory is corroding lampposts to the point where they collapse after a few years.
The report, based on research by scientists at the University of Zagreb, blamed the ammonia in the urine.
City officials who issued the report appealed to pet owners to make their dogs urinate somewhere else.
