Canadian authorities say a woman was killed and a 2-year-old girl was mauled in an attack at an Alberta residence last week.

According to CTV News, the victim owned the animal, which was identified as a Pitbull and boxer mixed breed.

The fatal attack took place inside the woman’s home in Rocky View, reports indicate.

Police believe the dog initially snapped at the toddler, leaving her with serious injuries. Officials say she is expected to recover.

At some point during the incident, the animal apparently shifted focus to the woman, killing her in what was described as an unprovoked act of aggression.

According to witnesses, the pet had not shown any evidence of such behavior and appeared to be a normal dog.

There was another dog inside the home at the time of the attack, police reported.

The 50-year-old victim was not immediately identified and police did not provide any details about her possible relationship to the toddler, as reported by CBC.

As of the latest updates available, both animals had been transported to a facility in Calgary where they remained quarantined.

Officials were said to be monitoring the dogs, but few additional details were immediately available.

“With any dog bite in Alberta if the dog isn’t euthanized right away, typically the dog will be quarantined … and that’s to monitor the dog for afflictions such as rabies,” said Royal Canadian Mounted Police Staff Sgt. John Spaans.

He said that, since one victim survived the attack, “it’s best to be monitored to see if they had potentially been infected.”
