The deadly mauling of a Pointe-aux-Trembles woman in her backyard may have come from a boxer, even though police described the dog as a pit bull.

The Humane Society International obtained a copy of the registration documents for the dog owned by Franklin Junior Frontal which states his dog was a boxer. 

In early June, Christiane Vadnais, 55, was mauled in her backyard by Frontal's dog.

Police stated at the time that the dog was a pit bull. They now say the investigation into the dog's breed is with the borough's dog inspector. 

Frontal's lawyer, Audrey Amzallag, told CBC News she could not confirm whether the permit labeling the dog a boxer was for the animal involved in the attack.

The incident set off a series of votes on the subject of dangerous dogs in Quebec.

Quebec City announced a pit bull ban shortly following the attack which was met with such resistance that police worried for the mayor's safety. 

Longueuil moved forward with a ban in early July even after Quebec City and Sherbrooke backtracked on theirs.  

Montreal announced a pit bull ban could be in place by September which led to pit bull owners saying they would move if needed.
