Reunited: Nine-year-old 'lifesaver' thanked by elderly Mandurah woman

An elderly Mandurah woman has been reunited with a nine-year-old girl who "saved her life" last week.

Dianne Isgar, 75, told the Mandurah Mail on Tuesday she wanted to thank four girls who came to her rescue during a severe asthma attack, moments after her dog was mauled at Frasers Landing in Coodanup on April 30.

On Saturday, Ms Isgar met Dudley Park girl Shaliah Cooper, 9, and her sister Tennessee, 4, to thank the pair after their grandmother notified the Mail of their good deed.

The other two girls could not make the occasion, but will also receive a letter and $25 from Ms Isgar.

Ms Isgar was walking her two dogs, before a large bull terrier mauled her small dog 'Bonny', causing serious stomach injuries and a vet bill exceeding $900.

She said the owner, in his late 20s, "threw his dog to the ground, kicking and punching it" in front of the children, before fleeing the park without apologising or providing his details.

Ms Isgar said she suffered a "severe" asthma attack before the four girls ran to her aid, with nine-year-old Shalia taking charge.

"She fetched my asthma puffer from the car and was quick to help me when I was struggling to breathe," she said.

"She saved my life and I am so grateful. The man did not even ask if I was alright - he just took off.

"These girls should receive a bravery award. They were very responsible. I am really happy I could thank them in person."

Dudley Park Primary School year 4 student Shaliah said she was not expecting to see such a "scary" incident while playing with her friends.

"The big dog wasn't on a leash and got the black dog and swung it around," she said.

"The man beat up the dog, which wasn't the right thing to do. I got sad that he hurt the big dog - it was scary.

She's always looking out for everyone.

"We came here to play and not see scary things, but we saw someone sad so we ran over and helped."

Shaliah's father Lucas Cooper said his daughter was always looking out for her six brothers and sisters.

"It's pretty amazing that she did that, but I am not too surprised," he said.

"She's always looking out for everyone. It's pretty poor behaviour from that man and he can learn from the girls.

"I am really proud."
