It’s just a small news item in the Los Angeles and San Diego newspapers…but it’s another story of how special dogs are – and how they use their detection skills to help humans.

On 26 January 2017, a therapy dog at San Diego Cooperative Charter School in Mountain View wouldn’t drink the water a teacher had poured for it from the classroom sink.

The teacher noticed a sheen on the water, which was tested and initially revealed the substance vinyl chloride.  Subsequent testing has revealed levels of lead some of which exceed health standards.

A district-wide water testing program is underway in all City of San Diego schools.

All because of one keen-nosed therapy dog with discerning tastes!
