An Auckland student had "chunks of flesh" ripped out of him after a dog attack on Tuesday morning.
The seven-year-old was near the Preston Rd entrance of Rongomai School in Otara when the dog launched at him.
In a Facebook post, the school says it was a "tan dog" and possibly a red-nose pitbull.
"Our student endured a couple of chunks of flesh being ripped from his arm, and was quickly rushed to the hospital," the post says.
"We're not sure who owns the dogs but it might be best for our students to avoid walking to school via the Preston Rd entrance unless they're with a group of other Rongomaites or [an] adult."
Auckland Council's animal management spokesperson Kerri Fergusson told Stuff the boy is at Middlemore Hospital being treated for bites and scratches to his leg and face.
"Our thoughts are with the boy and his family, who have been left traumatised by this incident."
She says animal management is taking the incident "very seriously".
"We will be speaking with the boy's family as soon as we can to get any more details about the attack."
Rongomai School asks people to contact Animal Control on 0800 462 685 if they have any information about the attack.
