A drug-sniffing dog has led to a methamphetamine seizure that authorities in Slovakia are calling the country’s largest ever.

The meth was found at the end of May with the help of Hutch, a service dog employed by the country’s financial administration.

Hutch went to work after customs officials became suspicious about the contents of two large metal containers for transporting liquids.
