The dog doesn't wear any medal at all

Please contact a veterinarian, an animal shelter or the police to verify whether the dog has got a microchip (as from 1.1.2007 in principle all dogs should have a registered marking). If the dog hasn't got a microchip, please announce it to the cantonal authority in charge (cantonal authorities) and inform the local authority in charge. You may also make an entry on the following sites: www.tier-gefunden.ch and/or www.stmz.ch (Schweizerische Tiermeldezentrale).
