‘King of Terriers’, Airedales are the largest of the terrier family and were originally named after the Aire Valley in West Yorkshire. The Airedale is multi-talented: it can be used for hunting, as a watchdog, and in police and military work. The Airedale could also be described as ‘war dog’, because over 3,000 Airedales were recruited for military service in WWI. They were used for locating wounded soldiers and carrying messages behind enemy lines. Sadly, two Airedales went down on the Titanic.
