Dogs Trust, known until 2003 as the National Canine Defence League, is a British animal welfare charity and humane society in the United Kingdom which specialises in the well-being of dogs. It is the largest dog welfare charity in the United Kingdom, caring for over 15,000 animals each year. Dogs Trust's primary objective is to protect all dogs in the UK and elsewhere from maltreatment, cruelty and suffering. It focuses on the rehabilitation and rehoming of dogs which have been either abandoned or given up by their owners through rehoming services.
Dogs Trust has 20 rehoming centres across the UK. Its first international rehoming centre opened in November 2009 in Dublin, Ireland. Its charity guidelines ensure that no mentally or physically healthy dog taken into the protection of its rehoming centres are euthanised. Dogs Trust also manages microchipping and neutering schemes in the United Kingdom and abroad, in order to reduce the number of unwanted litters of puppies and stray dogs.
