Dogs smell diabetes by detecting specific chemical changes in a person's breath or sweat when blood sugar levels drop (hypoglycemia) or rise (hyperglycemia), using their incredibly powerful sense of smell to identify volatile organic compounds like isoprene, which significantly increases during low blood sugar episodes, acting as a unique scent signature for the dog to alert their owner.

How do dogs act when they smell diabetes?

If the scent is detected by the dog, they then “alert” the person with diabetes, usually by touching them in a significant way such as pawing or nudging them. The handler then knows to check his or her blood sugar level. As a result, they may need to get something to eat or drink to prevent hypoglycemia.

Can dogs sense diabetes in humans?

Researchers from the University of Bristol have assessed how 27 dogs could detect some diabetes-related issues. The dogs were trained to alert their human in case of low or high blood sugar. The study found that they detected 83% of hypoglycemic episodes and 64% of hyperglycemic episodes.

How do dogs know when blood sugar is high?

Dogs have an amazing sense of smell and can detect many scents that human noses can not. When your blood sugar has spikes/lows, the scent of your breath changes. Service dogs can be trained to detect these scent changes and alert to them, so they can let their handler know if their blood sugar is spiking or dropping.

They sense time through routines, smells, and body changes, not abstract clocks.
