The Full Story

A plain summary built from the channels that reported this story.

Medical detection dogs are trained to alert their owners to changes in their bodies that can signal a medical emergency. Two such dogs, Kenny and Winnie, have transformed the lives of their owners, giving them independence and safety.

Kenny belongs to Kate Hegan from Shepton Mallet, who has Mast Cell Activation Syndrome (MCAS) and Postural Tachycardia Syndrome (POTS). MCAS can cause severe allergic reactions, while POTS leads to fainting multiple times a day. Before Kenny, Kate was chaperoned 24 hours a day and could not be left alone. Kenny alerts her when she is about to pass out, giving her time to get to a safe place. He has alerted to about 40 anaphylactic episodes in a year, and on one occasion, his warning allowed Kate to use her EpiPen and call an ambulance before her throat closed. The medical team told her that without Kenny, she would not have made it.

Winnie is a five-year-old poodle cross owned by May, who has an autoimmune condition that causes her to faint up to 15 times a day. May receives a treatment that replaces plasma containing bad antibodies, which has reduced her episodes to five to eight a day. Winnie was trained by Medical Detection Dogs to detect changes in May's body odour and taps her with her paw to warn her about five minutes before she faints. Winnie has also started tapping staff at the NHS blood and transplant unit where May receives treatment, alerting them to changes in May's blood pressure.

Both dogs use their incredible sense of smell. Dogs have 300 million scent receptors in their noses, compared to 5 million in humans. They can detect a teaspoon of sugar in two Olympic-sized swimming pools. The dogs are trained to associate a change in odour with a reward, and they alert their owners when that change occurs.

Medical Detection Dogs is a charity that trains these dogs and matches them with clients. They are expanding their work, including in the Bristol area, where they are looking for volunteers to help socialise puppies and transport dogs and clients. For Kate, Kenny has given her a future. As she says, 'With Kenny, it's just completely changed my life.'
