Stumpy is a handsome labrador who was destined for a career as a guide dog. Sadly, problems with a deformed leg meant it wasn’t to be. But then Stumpy found a new way to help others: by giving blood.

The nine-year-old labrador has saved more than 100 canine lives since the age of one by donating blood for emergency transfusions.

Stumpy has been crowned the United Kingdom’s most prolific blood-donor dog. He has a negative blood type which is especially valuable because it allows his blood to be given to any dog.

Stumpy’s owner, vet Elly Pittaway, says: “Stumpy obviously has no idea what he’s doing it for, but if he did, I’m sure he’d be very proud of himself.” [Source: Daily Mail, BBC News]
