The woman bringing a potential class action against the maker of treats that allegedly killed her dog doesn't have to open her Facebook account to the defense, a federal judge has ruled.

The 648 pages of her Facebook posts, with redactions, that she provided are sufficient, U.S. Magistrate Judge Maureen P. Kelly of the Western District of Pennsylvania held.

Milo's Kitchen, the maker of the dog treats, had asked the court to compel Lisa Mazur, who brought the suit, to produce a complete and unredacted Facebook data file and her username and password for the site. Milo's argued that when Mazur had a public Facebook page, she had posted a statement blaming another major manufacturer of dog food for her dog's illness.
