In a statement Thursday, the city said the application was filed under the Dangerous Dogs Act, noting that a court date will be scheduled to consider the application. On June 5, a woman identified by neighbors as Betty Ann Williams was allegedly mauled by three dogs in a back alley while gardening in the Northwest Capitol community. Neighbors told CBC News they held Williams while she waited half an hour for an ambulance. An EMS spokesman said in June that paramedics took the woman to Foothills Medical Center, where she later died. Since then, EMS response time has come under scrutiny. Officials in charge of Alberta’s emergency response system said the call was initially recorded for the police response, which caused a delay. But neighbors said they were clear in their 911 calls that EMS was urgently needed. Police said the dogs were owned by a neighbor. Authorities believe the dogs are a mix of a North American Pit Bull Terrier, a North American Staffordshire mix and an American Pit Bull. The city added in its statement that community peace officers seized the three dogs and the animals will continue to be detained depending on the outcome of the petition. “Dangerous Dog Law enforcement is only concerned with the disposition of the dogs and is asking the court to order the dogs involved in the incident to be humanely euthanized,” the city wrote in a statement. An investigation by the Calgary Police Service and Calgary Community Standards is ongoing.
