Today I encountered two very different sniffer dogs at the Customs and Excise Museum.
Two of our roleplayers, dressed as the larger-than-life characters Smugglebuster the customs officer and Sniffer the dog, were greeting visitors to the museum.
Outside I met the real deal - customs officer Claire Dewhirst with her sniffer dog, who were at the museum today doing demonstrations for the public.
If you missed today's demonstrations then you have another chance to see a real sniffer dog at the museum next Thursday.
Smugglebuster and Sniffer will also be back at the museum soon. For full details of all the events and activities taking place over the next few weeks have a look at the What's On listings.
