The PDSA Dickin Medal was instituted in 1943 in the United Kingdom by Maria Dickin to honour the work of animals in World War II. It is a bronze medallion, bearing the words "For Gallantry" and "We Also Serve" within a laurel wreath, carried on a ribbon of striped green, dark brown, and pale blue. It is awarded to animals that have displayed "conspicuous gallantry or devotion to duty while serving or associated with any branch of the Armed Forces or Civil Defence Units". The award is commonly referred to as "the animals' Victoria Cross".

The People's Dispensary for Sick Animals (PDSA) is a veterinary charity in the United Kingdom. It was founded in 1917 by Maria Dickin to provide care for sick and injured animals of the poor. It is the UK's leading veterinary charity, carrying out more than one million free veterinary consultations a year, and was until 2009 the largest private employer of fully qualified veterinary surgeons and veterinary nurses in the UK. Use of the PDSA's services are restricted to those within their catchment area.
