Book Description
for Pig Detectives by Rosie Albright
From the Publisher
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.
