A 16-year-old boy has been charged with murder after the body of 54-year-old woman was found dead at her home in west Wales.
Dog rescuer Ffiona Scourfield, who was also known as Suzi Wales, lived in the small town of St Clears in Carmarthenshire.
Dyfed-Powys Police were called to the property just before 6pm on Tuesday.
A volunteer for the UK German Shepherd Rescue, Ms Scourfield was described by colleagues as someone who worked "tirelessly to make the world a better place for animals".
A Facebook tribute showing a picture of Ms Scourfield fundraising with her rescue dog Bruno said "she could always be relied upon to help a dog in need".
The charity described German Shepherd Bruno as her "absolute world".
"To say the rescue is devastated would be a massive understatement," the post said.
No one else is wanted in connection with the incident and Ms Scourfield's family have been informed.
The teenager will appear at Llanelli Magistrates' Court on Friday.
