Dog saves owner Bernadetta Henry's life every night | Metro.co.uk
Bernadetta Henry suffers from sleep apnoea, which affects her airways and causes her to stop breathing several times each night.

Bernadetta Henry and Boris, who acts as a hearing dog
But faithful Boris lies next to the grandmother as she sleeps and carefully monitors her life-threatening condition through the night.
The bichon frise listens out for her - and puts his paw on her chest to wake her when her breathing stops.
'He means everything to me. If it wasn't for him, I would be dead,' said Mrs Henry, from Llangollen, Denbighshire, in north-east Wales.
Boris has been her hearing dog since she became almost completely deaf as a result of a blood clot. Mrs Henry later had an allergic reaction to the blood-thinning drug warfarin, resulting in a brain haemorrhage.
After physiotherapy, she was confined to a wheelchair, making her more dependent on her family.
But, since the death of her husband five years ago, Mrs Henry, who is in her 70s, has been reliant on Boris and depends on him to alert her when the phone or doorbell rings and when the cooker's timer goes off.
'I couldn't live on my own without him and we both love each other. He's full of fun and can be very mischievous,' she said.
