Seven-year-old Elcee Heke is back at school after a dog attack outside Rongomai School in south Auckland.

As Elcee Heke approached his Auckland school's gates, two dogs attacked him, "scratching and shaking him like a rag doll".

The 7-year-old was on his usual walk to school on March 3 when two dogs attacked him, leaving him with severe puncture wounds on his legs and scratches on his arms and face.

His mum, Alexandra Heke, said nothing could have prepared her for what happened, and more than a week later, she tears up talking about the "worst day" of her life.

TORIKA TOKALAU/STUFF Elcee's mum Alexandra says the day her son was attacked by dogs was the worst in her life.

"I was in shock, Elcee was in shock, there was blood everywhere," Heke said.

"He was bawling his eyes out and I was the same. I tried to stay strong for him but I knew my son was in so much pain, he was shaking so much."

TORIKA TOKALAU/STUFF Elcee Heke was attacked by two dogs whiel walking to school.

Her son had been walking the short route from his house to Rongomai Primary School in Ōtara, south Auckland, when the attack happened.

She was alerted to the dog attack just minutes after it happened and ran out the house to see if her son was okay.

One of the dogs had latched its teeth onto Elcee's knee while the other was on his back, "scratching and shaking him like a rag doll", she said.

The dogs were described as tan coloured and did not appear to have any owners with them.

"He had bites on his knee and at the back of it. The dogs also dragged their teeth across his knee when Elcee was fighting them away."

She said Elcee also has visible scratch marks on both his arms and face.

TORIKA TOKALAU/STUFF Elcee had puncture wounds on and around his knees, and scatches on his arms and face.

"I never thought anything like this could happen. That was the worst day of my life."

Elcee had to be rushed to Middlemore Hospital for his injuries.

Heke thanked the teenager who came to Elcee's rescue that day, and all the teachers and parents who acted quickly to make sure her son was okay.

"I am so angry. Keep your dogs on a leash or behind closed gates, not running around near schools.

"I never want this to happen to someone else's baby."

Elcee was back at school six days after the attack but Heke said he freezes up every time he sees dogs nearby.

"I felt so helpless seeing him like that after the attack but he's just happy to be back at school and being around his friends again."

Rongomai School spokesperson Trina Mataroa said the support from the Ōtara community has been amazing.

Parents have voluntarily been monitoring roads before and after school to make sure students get to school safely.

Animal Management impounded one dog that was found roaming in the area right after the incident but could not confirm if it was involved in the attack.
