I WAS interested to read about Claire Tilby and her son, Tyrese, and the impact diabetes has had on their life (Life, November 11).
Without the use of 12 dogs to discover insulin, 51m Type 1 diabetics alive today would have died painful deaths. In the UK alone, there are thought to be 17,000 diabetic dogs, who would also have passed away.
As we mark World Diabetes Day, we might also spare a thought for the animals whose sacrifice saved so many lives, as well as the animals whose sacrifice is helping to lead us towards new treatments for diabetes.
