The brave donor dogs giving blood to help others
Just like humans, sick and injured dogs may be in need of a vital blood transfusion.
The Pet Blood Bank runs a blood donation service for dogs, helping to top up supplies that vets can access in emergencies.
Operating like a human blood bank, fit and healthy dogs between the age of one and eight can donate several times a year.
Each unit of blood can help save up to four other canines, often meaning the difference between life and death for seriously ill patients.
The BBC visited a donation session in Dunfermline to meet two veteran donors, Fender and Sherbert.
