Lawsuit Claims Bayer HealthCare and Merial Limited Make False Claims For Flea and Tick Products

A class action lawsuit in Ohio has been filed on behalf of dog and cat owners alleging, among other things, that Bayer HealthCare, LLC, and Merial Limited regularly make false and deceptive claims in advertisements for their flea and tick pet products.  Bayer is the manufacturer of the family products made for dogs and cats under the trade names Advantage and Advantage II.  Merial is the manufacturer of the family of products made for dogs and cats under the trade names Frontline and Frontline Plus.  These products are sold as treatments for dogs and cats suffering with fleas, ticks, adult flea eggs, larvae, mosquito, heartworm, ear mites, and sarcoptic mange.  While each one of the individual products targets only a limited subset of the pet aliments, all of the products target fleas and their larvae.  The lawsuit alleges that Bayer and Merial collectively sell approximately $2 billion of these products annually under the allegedly false and/or misleading assertions claiming that the products: are self-dispersing and cover the entire surface area of the dog or cat’s body when applied in a single limited spot; are effective for one month and require monthly application to continue to be effective; do not enter the blood stream of the pet and instead move across the pet’s skin to cover the pet; and are waterproof and remain effective following shampoo treatments, swimming, or after exposure to rain or sunlight.  The suit seeks to prevent Bayer and Merial from continuing to allegedly misrepresent these products and seeks to recover damages on behalf of all those who purchased the products.  The attorneys at Balkan & Patterson, LLP are experienced in class action litigation and will act to protect consumers against corporate wrongdoers.
