Pig Detectives / Cerdos detectives
Animal Detectives / Detectives del reino animal
While some pigs live on farms and roll in the mud, others are performing valuable services to people. Pigs have a great sense of smell and have been put to work for centuries sniffing out truffles, which are highly-prized mushrooms used in cooking and to make oil. Pigs are also used to sniff out bombs and drugs, and to do search and rescue work.
