The RCMP in Fort Liard, N.W.T., are trying to piece together what led to a vicious dog attack in the community last weekend.

A nurse who works at the health clinic was attacked by at least two dogs while walking on a remote gravel road by the airport.

The woman sustained serious bites to her scalp.

The dogs were roaming off leash during the attack.

"She was walking along as she came across several dogs that were actually with their owners and the dogs proceeded to attack her. Apparently she fell to the ground and she sustained quite serious injuries," said RCMP Cpl. Monica Schimanke.

The woman was later flown by air ambulance from Fort Liard to a hospital in Edmonton. She is expected to return home later this week.

The RCMP plans to meet with the community‚Äôs chief to talk about dog safety. The community currently has no dog by-laws.

The RCMP said charges could still be laid.
