For instance, studies have shown that dogs can be trained to alert their owners when their blood sugar is low, and there is evidence that they can also detect cancer.

The study, which was published in the journal Frontiers in Physiology, found that dogs were able to detect changes in body odor before their owners showed any visible signs of fainting. While more research is needed to confirm these findings, they suggest that dogs could one day be used to help people with conditions like epilepsy or diabetes by warning them of an impending attack.  G...
