Dogs are not allowed in the exhibits and visitors facilities. This is also valid for guide dogs. On the one hand dogs can be a stress factor for the animals living within the exhibits and on the other hand these animals can also be dangerous for dogs.
For dogs there is a "Dog Hotelâ under the entrance bridge. The large enclosures are equipped with a water dish. This service is free of charge, however a deposit of CHF 20.- is requested when picking up the key at the reception.
