The Dogs of War: The Vital Roles of Animals in World War One

Animals were used in the First World War on an unprecedented scale.

Horses were certainly the most important animals in the war effort, but numerous other animals played their part – particularly pigeons and dogs.  The front required constant, huge supplies of munitions and supplies, and the transport of massive armies meant that animals had an essential role to play as beasts of burden.

By World War Two most of the supply roles had become mechanized, so the First World War was unique in that modern problems were met with animal solutions.

Horses and Cavalry

While the romantic ideals of gallant mass cavalry charges were soon proven ineffective by rapid firing rifles and machine guns, they still had a major role to play in reconnaissance and logistics, along with of plugging advances quickly.

At the beginning of the war most sides anticipated a fluid war which would require extensive use of cavalry

But advances in small arms and artillery meant the battlefield was rarely a good place for horses


As artillery became more powerful, battlefields were increasingly devastated – often turning No Man’s Land into a largely impassable quagmire of mud. 

On the first day of the Battle of Verdun 7,000 horses were killed by shelling


Horses and mules maintained a very important role in logistics

Horses and mules had a particularly important role transporting artillery and munitions

 In the Middle Eastern campaign, the war remained fluid – often camel replaced the roles of horses as cavalry mounts

Horses had important roles to play in transporting artillery, and when batteries were gas shelled horses needed similar protection to the men

80% of horses tended to by the AVC were able to return to the front.

By the end of the war, 800,000 horses and mules were in service in the British army

With so many horses enlisted in the war effort, workers were forced to look to alternative, more exotic sources of animal labour

Pigeons and Communication

Pigeons were another multi-purpose animal in the war effort. In an age of under developed telephony and battlefield radio, they served in important roles for relaying messages.


In Britain killing, wounding or molesting a homing pigeon was punishable with 6 months imprisonment


This came into force after the Defence of the Realm Act (1916).

Cher Ami saves the lost battalion

One Pigeon was named ‘Cher Ami’ (Dear Friend) and was awarded the Croix de Guerre avec Palme for her assistance in saving 194 American soldiers trapped behind German lines in 1918. She made it back to her loft despite having been shot through the breast, blinded in one eye, covered in blood and with a leg hanging only by a tendon.

Some pigeons were equipped with cameras to survey the battlefields


Small, quick and reliable, pigeons proved excellent on reconnaissance missions.

Dogs and Cats

These normally domesticated animals served as logistics assistants, medical assistants and as companions to fighting men.

Mercy Dogs were sent into No-Man’s Land to search out the wounded


They carried supplies so that a casualty could treat himself, or they simply provided companionship to the dying in their final moments.

Messenger dogs were often used to relay information between different lines

Sergeant Stubby: The most decorated dog of the war


Sergeant Stubby started out as the mascot of the 102nd Infantry, 26th Yankee Division, and ended up becoming a full-fledged combat dog. Brought up to the front lines, he was injured in a gas attack early on, which gave him a sensitivity to gas that later allowed him to warn his soldiers of incoming gas attacks by running and barking. He helped find wounded soldiers, and even cornered and captured a German spy who was trying to map allied trenches.

A dog born into warfare


This dog was born on the battlefield and adopted by a French Howitzer battery. He was injured twice and treated by the Blue Cross vets who bandaged his lacerated ear.

Individual regiments often had their own animal mascot

The First World War is rightly remembered for the enormous loss of human life, but it should not be forgotten that many animals were also required to make that ultimate sacrifice.
