Sydney: An elderly woman was attacked by a large kangaroo on a farm in Australia and was lucky to be alive after a pet dog leapt to her aid

her son said on Saturday.
The 2-metre kangaroo lunged at 65-year-old Rosemary Neal without warning Friday as she went to check on some horses on the property near Mudgee 265 kilometres northwest of Sydney

son Darren Neal said.
"The kangaroo just jumped up and launched straight at her

" he said. "He hit her once and she just dropped and rolled. My dog heard her screaming and bolted down and chased him off.
"If it wasn't for the dog

she'd probably be dead."
Rosemary Neal was hospitalised with a concussion and deep cuts to her face

hands and back

he said.
Kangaroos are widespread across Australia and there are dozens of species ranging from tiny

500-gram potoroos to red kangaroos

the world's largest marsupial that can grow past 1.8 metres tall and weigh more than 90 kilograms.
Most species are not considered aggressive toward humans

and attacks are extremely rare. But males fight each other for mates

rearing up on their tails to scratch at the soft flesh of the bellies of their rivals with the powerful legs they more commonly use for their trademark leaps.
Darren Neal said mobs of kangaroos had become common on their farm

and his mother thought nothing of walking through them. Usually

they just jumped away.
"You can't drive down the street without swerving to miss them

" he said.
