The female owner of a boxer pitbull cross was attacked and killed in her home near Langdon on September  15, shortly after 6 p.m. 
 
The dog showed no signs of aggression before the attack that initially started with a three-year-old female, but then turned on the owner once she intervened. 
 
When EMS and emergency services arrived the 49-year-old female was pronounced dead on the scene and the toddler was taken to the hospital with serious non-life threatening injuries. 
 
The dog and a second dog in the home were taken to Calgary and quarantined.
