A veterinary practice in the East Midlands has set up its own blood donor scheme to encourage dogs to donate blood for emergency surgery.
Ben's blood has saved the life of a collie
The Park Veterinary Group in Whetstone, Leicestershire has asked dog owners to come forward and register their pets so a blood bank can be built up.
Ben, a large brindle and white greyhound, has donated blood several times, once saving the life of Molly, an ailing collie cross who is anaemic.
"The donors must have a good temperament and be easy to work with," said veterinary surgeon Ciara Downes.
A tin of food
"We check their blood type and then take blood from their neck vein - we take about 200-300 millilitres of blood."
"The dogs don't get tea and biscuits, but they do get a nice tin of dog food afterwards."
Ms Downes said not all dogs are suited to giving blood - temperament is all important so dogs that are giddy or snappy are not acceptable.
"You want a healthy dog or reasonable weight - a little Yorkshire terrier isn't going to donate a lot of blood.
"We like dogs that weigh more than 15 kilograms," she said.
Ben is a very placid dog with a good nature, she said, but he is still in the care of a Leicestershire rescue centre.
Ms Downes said any owners with potential dog donors should contact their local surgery for advice.
