A woman who was mauled by a grizzly bear calmly called 911 with the animal behind her 'getting ready to attack' again.

After hearing her daughter's dog barking from their property next door in Frederick, Maryland back in 2016, Karen Osborne got her dog Miles and went to investigate.

As the then-63-year-old went round to check what made the noise at around 9pm at night, out of nowhere, a 200lb black bear emerged from the woods.

Karen was completely defenseless and so dropped to the floor and curled up into as small a ball as she could.

Alas, the bear kept coming, 'bit [her] face' and 'threw' her to the ground, she told Inside Edition.

Despite being mauled by the animal, Karen managed to grab her phone and call 911 for help and the recording of her conversation with an operator is extraordinary given how calm she sounds despite the horror of the incident.

A video posted to YouTube by Inside Edition features a recording of Karen's call to emergency services.

In the call, Karen says: "I've been attacked by a bear. My arms are broken, my leg is broken I think. I'm chewed up on the back of my head."

Karen was told animal control, police and an ambulance had been dispatched.

She then said: "Please don't leave me."

Karen was reassured services were coming 'as fast as they can' but when the call handler asked where the bear was now, the situation grew even more tense, with the bear's growls and murmurs being audible on the recording.

Karen explained: "He's behind me and he's snorting and stomping and digging in the ground like he's getting ready to attack

"I've been attacked by this bear. He's coming back. I'm bleeding and I'm going to die. Please hurry...Oh my God, here he comes."

According to a GoFundMe later set up to support Karen, the bear attacked her for a whopping 35 minutes - with the beast returning to her 'four separate times'.

When authorities arrived at the scene, the bear was shot dead and its cub was tranquilized.

Miraculously, Karen survived the attack but the bear more than left its mark, breaking her pelvic bone, crushing her lung and leaving her with 'wounds all over [her] body'.

Wildlife officer Paul Pedido said at the time the bear likely attacked Karen because she accidentally walked in-between it and its cub.

Karen resolved: "I don't want to tango with any more bears, I think I've had enough bears."
