Bring a bottle: Viennese dog owners told to dilute their pets’ urine to protect trees
Vienna city officials have advised dog owners to dilute their pets’ urine with water before it reaches trees. The guidance warns that concentrated ammonia in urine can erode bark and harm urban greenery. By watering down the waste, owners can reduce chemical damage and help preserve the health of the capital’s trees. The environment department says the step targets mature trees in parks and streets.
