Demand the End of Grey Hound racing Dogs being exported to China

I watched the program on 7.30 Report last night and the inhumane treatment of Australian Grey Hound racing dogs over in China after they are of no use racing was so disturbing to me, they are given an injection of some kind of poison and these humans if you can call them that put their feet on the poor dogs head until they are dead and then thrown away like rubbish. Shame to the Australian Politicians that allow such cruelty to innocent animals that humans use for their pleasure, DISGUSTING!
