I had not known that many Greyhounds have what is sometimes known as ETS (Escaping Tongue Syndrome), with their very long tongues often falling out the sides of their mouths, and even sticking to the floor!
The Greyhound racing industry in Australia is responsible for many thousands of Greyhound deaths every year. This is the personal story of one of those poor dogs, but at least this one had a precious few weeks of normal life at the end.
