A US military dog who lost her leg on duty travels to London to become first to receive 'VC for dogs'

A US military dog who lost her leg while on duty in Afghanistan has become the first to be awarded the animal equivalent of a British Victoria Cross.

German Shepherd Lucca, aged 12, completed over 400 separate missions during six years of active service with the U.S. military, where she would sniff out explosives.
