Alhanna Butler, from Doncaster, was told to get rid of her Akita dog Keola when she became pregnant.
But in a dramatic twist, the hero pooch convinced Alhanna to go to hospital by “barking, whinging and nudging” her.
She said: "Keola looked so sad and I knew something was bothering her. She just sat there staring at me and
The dog’s fears were confirmed when Alhanna collapsed in a hospital corridor.
The mum-to-be said: "I was 20 weeks pregnant and had been so unwell for weeks, I couldn't walk... and I hadn't kept anything down for weeks.
"Doctors put it down to me being so small and my spine not being able to manage with the extra weight well and just normal pregnancy symptoms.”
It was discovered that Alhanna had a double kidney infection, which was “one of the worst cases [doctors] had ever seen”.
She said: "On top of that I had an antibiotic resistant bug that had only ever affected one other person in the UK.
“It was killing me and the doctors told me if I had left it any longer I would have died and more than likely my son also.”
She paid tribute to hero Keola in a touching facebook video.
The heartwarming clip has racked up over 46,000 shares.
Pets have been known to save their owner’s lives in other cases.
Earlier this month, a Border Collie saved an American family’s life after the clever dog alerted them to a Carbon Monoxide leak.
And last month, a dog stopped a West London Librarian from choking on a biscuit when her pet papillon-cross administered a “Heimlich-like manoeuvre”.
