Dixon is engaged with various animal rights organisations and is also a pescetarian. She is Vice-President of the League Against Cruel Sports, a charity which works to end cruelty to animals in the name of sport and featured in a charity appeal due to concerns that the Hunting Act 2004 could be repealed. In 2012, Dixon travelled to Romania with World Animal Protection to rescue two brown bears from Onesti Zoo, which had closed years previously. The bears were moved to a nearby sanctuary. In 2014, Dixon encouraged her Twitter followers to sign an online petition calling for the ban of slaughtering animals without being stunned first. UK and EU law requires that animals must be stunned before slaughter, unless for religious purposes (Halal or Kosher meat). Dixon is also a supporter of the PetRetreat scheme launched by the Royal Society for the Prevention of Cruelty to Animals (RSPCA). The scheme fosters pets belonging to victims of domestic abuse, who often have to leave behind animals, as many refuges and safe houses do not allow pets. The pets are later reunited with their original owners when possible.
