The RCMP is being asked why officers shot and killed a dog during an arrest caught on video.
Cote is currently serving a 22-month sentence after pleading guilty for assault causing bodily harm.
The video was originally published last year but came to wider attention this week after being re-uploaded to LiveLeak.
The grainy cellphone footage was taken by Cote's girlfriend's sister and starts midway through the arrest. It shows the family's dog Duke lying on the grass when an officer calls out, "Get a shotgun to put this dog down." Another officer then approaches the dog with a shotgun and shoots him from a few feet away as the person filming cries for her pet.
The family disputes that Duke behaved aggressively.
Justine O'Soup, Cote's girlfriend, told CBC News the police overreacted and that Duke could still have been saved, despite being injured.
"Duke wasn't acting aggressive," she said. "Even if my dog was attacking the [police] dog, shooting him seven times in the body isn't the way to handle it. It's cruel the way they shot him. Why did my dog have to die?"
O'Soup has filed a formal complaint against the RCMP over the incident.
BuzzFeed Canada contacted O'Soup for comment.
The video contains graphic content.
Stories of pet dogs being shot by police often lead to intense backlash against the police departments involved.
Police officers say they get unfairly vilified when dogs are injured or killed.
