The attack happened yesterday afternoon at a residential property in Dún Laoghaire, south Co Dublin.
It is the latest serious incident involving dogs in recent months – there was a fatal attack in Limerick in June.
Emergency services received reports of a dog attack at around 1pm yesterday.
Gardaí, including members of the armed support unit, raced to the scene.
Paramedics were the first to arrive, but were unable to tend to the woman as the dogs posed a threat to them.
When gardaí arrived a short time later, they moved the animals from the kitchen into an adjoining room.
The woman was treated at the scene before being taken to hospital with serious injuries.
Gardaí have begun an investigation into the incident and are trying to identify the registered owner of the dogs.
It is understood they were in the care of a person known to the victim. They were taken into the custody of the local warden.
It has not been established if the breed of the dogs is on the restricted list.
A garda spokesperson said: “Gardaí were alerted by emergency services to an incident at a residence in Dún Laoghaire, Co Dublin.
“A woman was attacked by a number of dogs. She has been taken to St. Vincent’s Hospital for treatment. Investigations are ongoing.”
Concerns have been raised about the number of serious dog attacks around the country in recent months.
On June 3, Nicole Morey was killed after two dogs attacked her at her home in Ballyneety, Co Limerick.

One of the dogs, an XL Bully, was shot dead at the scene by gardaí. Three other dogs at the property were later destroyed.
The day before, gardaí received reports of a care worker being attacked by a number of dogs in the Maryland area of south inner-city Dublin.
Weeks later, a man needed hospital treatment after being attacked by a rottweiler in Co Donegal.
He was jogging on a greenway between the villages of Muff and Quigley’s Point on the Inishowen peninsula when the dog pounced.
Minister for Rural and Community Development Heather Humphreys recently announced a ban on XL Bully dogs. From next month, the importing, breeding, selling and re-homing of such animals will be illegal.
