Man’s best friends have long been put to work, and a recent medical study has shown hounds can be trained to smell malaria in children. Is there anything they can’t do?
Truffles, ghosts and now malaria: things dogs can sniff out
Malaria is a disease with many identifiable symptoms, including sweating, vomiting and bloody stools. However, forget the traditional signs, because dogs can apparently smell it on you.
