Sniffer Dogs: How Dogs (and Their Noses) Save the World
by Nancy Castaldo (Author)
Booktalk: Anyone who has ever spent time with a dog knows that dogs love sniffing! They sniff out hidden food, dirty socks, and the visitor who comes to the door. But some dogs work with police officers, soldiers and even scientists to put their “sniffers” to work. Sniffer dogs make use of the amazing biology behind their noses to protect people from bombs, catch criminals smuggling drugs, or help researchers locate a hard to find snail in a forest.
Snippet: During World War I and Wrld War II, dogs were used to help locate injured soldiers on or near the battlefield. These dogs were also called casualty or ambulance dogs. They were also used by the military as scouts, trackers, sentries, and messengers.
