The most loyal and loving of pets come to the rescue of humans once again. Recent research has shown that dogs can be trained to alert diabetics about dangerously falling blood sugar levels.
During the study, researchers found that "glycaemia alert dogs" were able to spot the change in blood sugar levels of their owners and warn them.
Dogs have the intelligence and capability of detecting danger due to their sense of smell. They can pick up the chemical alterations in their owner's sweat or breath.
Similar research conducted has pointed to the ability of dogs to spot cancer by getting the scent of chemical compounds released by tumors.
Dr Nicola Rooney, who led the study said, "Some of the owners also describe their dogs responding even before their blood sugars are low but as they start to drop, so it is possible that the dogs are even more effective than this study suggests."
