Wouldn't it be nice to have a dog in every doctor's office to screen for disease?

oh those kinds of dogs, what a shame thought you were talking about something else. I'm reminded of the st bernard from the hamlet adverts, well man's best friend is a cat, sorry, and if my cats lick me let alone anyone else it means its dinner time. There is some merit to this idea though, as pets are most intuitaive at times so who knows and dogs don't need batteries unlike the electronic gizmos.
