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; only those living within the PDSA's catchment areas can use their services.
