The person who posted the picture said the woman was aware she was not supposed to bring her dog into St. Mary's Cemetery, the Canadian Broadcasting Corp. reported Friday. The cemetery has signs posted that no dogs are allowed.
"After being notified that dogs are not allowed, this woman admitted to knowing that dogs aren't allowed (apparently the rules don't apply to her). ... I hope a dog craps on her grave. What a disrespectful woman," said the post.
The post has generated a huge response with a dozen pages of feedback. Many of the responders are angry at the woman.
But some say the photo should not have been put online and instead should have been given to Calgary police or the managers of the cemetery.
Mike Morrison, a Calgary blogger, said he believes social media should be used for positive discussions and encouraging people to behave well.
"There's no privacy anymore and everything is up for public consumption and I don't think that's fair," he said.
