A $1 million lawsuit filed by a Dallas pet-sitting company against a Plano couple who wrote a one-star review has been dismissed.

Prestigious Pets and its owner filed the lawsuit against Michelle and Robert Duchouquette, accusing them of defamation, business disparagement and a breach of contract after the couple posted the negative review on Yelp.

Thompson & Knight, the law firm representing the Duchouquettes, said in a prepared statement that a Dallas County district court granted the couple's motion to dismiss the case Friday.

The Duchouquettes argued the case should be dismissed based on the Texas Anti-SLAPP statute, meant to allow judges to dismiss frivolous suits filed against people who speak out about a matter of public concern.

Prestigious Pets sought between $200,000 and $1 million in damages, up from an initial $6,700, which Bill Richmond, the attorney for the company, said was made to reflect a loss in business.

Richmond said Prestigious Pets is reviewing its options and may consider appealing the decision.

"The pets and this business mean everything to the company and its owner," he said in a statement. "They remain confident that Texas law supports enforcing their contract, including the non-disparagement clause, particularly given the proof presented that Prestigious Pets never agreed to care for the fish, was not paid or hired to care for the fish, and the fish was never harmed."

He said the company tried to resolve the issues before taking legal steps, but "it is unfortunate that those efforts were ignored in favor of the Defendants' ongoing media campaign."

The Duchouquettes hired Prestigious Pets in October 2015 to watch their two dogs and betta fish, Gordy, while they were on vacation, according to court documents.

In the Yelp review, the Duchouquettes said their betta fish's tank looked murky in a video feed, the billing was messed up and the company tried to charge to return the keys to the family.

"The one star is for potentially harming my fish, otherwise it would have been 2 stars," the review stated.

The family said in the review that the care for their dogs "was fine."

Prestigious Pets said the Duchouquettes violated a nondisparagement clause in their contract by posting the review, and that their statements were false and defamatory.

In the complaint, Prestigious Pets and its owner Kalle McWhorter said the family did not initially tell the company it had a fish and that the sitter agreed to feed the betta for free after the Duchouquettes "demanded" it. The sitter did not agree to clean the fish bowl or change the water and was told to feed it less, according to court documents.

Documents provided by Richmond, the company's attorney, show only two pets on the contract -- dogs Bogey and Barley.

The complaint also said McWhorter and her husband "have had to deal with numerous rape and death threats" and other forms of harassment.

The Duchouquettes' review is still up on the page, which has an average of 4.5 stars, but the Yelp page for the company now features a consumer alert reminding reviewers that they have a First Amendment right to express their opinions.

The business "may be trying to abuse the legal system in an effort to stifle free speech, including issuing questionable legal threats against reviewers," the alert states.
