Send them to Texas?

How embarassing. Drug detection dogs in Australia were having a hard time sniffing out cocaine. An investigation revealed they had mistakenly been trained using talcum powder instead of the drug when the Austrailian feds furnished the trainers with the bogus sample.

Assistant Commissioner Evans says the dogs involved will need to be re-trained.

"I'm sure our dogs have got very soft, nice smelling noses at the moment, but
they are in fact trained in detecting talcum powder so that means that they will have to be re-trained in detecting cocaine," he said.

However, as someone pointed out in an earlier story on this, the dogs could be useful in finding lost babies with their present training intact. It also occurs to me that town in Texas where they busted all those folks for wallboard chalk might be interested in them as well.
