Just days after the game, then called "Dog Wars," was pulled from the apps store's Web site over trademark concerns, the creaters, Kage Games, had it back up for sale with the revamped name.
The game notes the controversy it has raised and is pitched as "an app that will never appear in the iPhone App Store!"
"Raise your dog to beat the best!" the marketing copy says. "Feed, water, train and FIGHT your virtual dog against other players ... ."
It cheekily concludes "No dogs were harmed in the making of this app ... a few flies got swatted."
The Los Angeles Times reported Kage Games said in an e-mail to the newspaper this week the game's aim is to educate the public on the evils of animal cruelty.
The game has come under fire from several directions, including the head of the Los Angeles police union, the Humane Society of the United States and NFL quarterback Michael Vick, who served time in federal prison for his role in real-life dogfighting.
"The game teaches users how to breed, train, fight, medicate and kill virtual dogs," LAPD police union President Paul Weber wrote to Google Chief Executive Officer Larry Page in a letter asking he ban the game from the site. "The entire concept is repulsive and sickening."
The Times said it wasn't known what Google's next step might be.
