False Advertising Roundup: Misleading Pet Supplement Claims and Deceptive Email Subject Lines

Two developing class action stories are drawing attention in early 2026 — one involving a major dog supplement brand accused of misleading marketing, and another exposing a wave of lawsuits targeting national retailers over deceptive promotional emails. Here's what consumers should know.

1. Cosequin Dog Supplements — $11.5 Million Settlement

Deadline: Check the settlement administrator's website for the current claim filing deadline

Estimated Payout: Varies based on the number of valid claims filed and purchase history

Who Qualifies: U.S. consumers who purchased Cosequin dog supplements during the applicable class period

Nutramax Laboratories has agreed to an $11.5 million class action settlement to resolve allegations that it advertised its Cosequin line of dog supplements using misleading claims, according to settlement records. The lawsuit alleged that Nutramax's marketing overstated the health and efficacy benefits of the products — representations that, plaintiffs argued, persuaded consumers to pay a premium price they would not have otherwise paid.

Nutramax has not admitted wrongdoing as part of the settlement. The company's decision to resolve the case does not constitute a legal finding that any claims were false or misleading.

Dog owners who purchased Cosequin products during the class period may be eligible to submit a claim for a portion of the settlement fund. The amount any individual claimant could receive depends on the total number of approved claims, the volume of purchases documented, and whether proof of purchase is required or available.

2. Misleading Email Subject Lines — CEMA Class Actions Targeting National Retailers

Deadline: Varies by individual case — litigation is ongoing

Estimated Payout: Statutory damages under Washington's CEMA; amounts vary

Who Qualifies: Washington state residents who received allegedly deceptive promotional emails from named retailers

A significant wave of class action lawsuits is taking shape in Washington state, targeting national retailers over the use of allegedly misleading email subject lines in promotional campaigns. The suits are filed under Washington's Commercial Electronic Mail Act, commonly known as CEMA, which prohibits deceptive subject lines in commercial email messages.

The litigation was triggered in large part by the Washington Supreme Court's 2025 ruling in Brown v. Old Navy LLC, which clarified the scope of consumer protections under CEMA and opened the door to broader private enforcement. According to legal observers, plaintiffs in these cases allege that retailers used subject lines — such as urgent-sounding discount offers or false countdown language — that misrepresented the nature or contents of the emails.

Defendants in these cases have pushed back aggressively. According to legal analysis of the emerging case law, retailers have increasingly raised two primary defenses: first, that CEMA is preempted by the federal CAN-SPAM Act, which sets a national baseline for commercial email regulation; and second, that CEMA's statutory damage provisions raise constitutional due process concerns. District courts, however, appear largely skeptical of both arguments, according to recent legal reporting on the cases — a development that could sustain the litigation as it moves forward.

Consumers who are Washington state residents and who believe they received promotional emails with deceptive subject lines from a major retailer may want to monitor these cases for further developments.

How to claim: These cases remain in active litigation. No settlements have been announced at this time. Consumers interested in potential eligibility may wish to consult an attorney familiar with Washington consumer protection law.

Key Takeaways

• Pet product marketing is under scrutiny. The Cosequin settlement is a reminder that efficacy and health claims in pet supplement advertising can form the basis of consumer fraud litigation — even when the products are widely sold and trusted by pet owners.
• Your inbox could be evidence. The CEMA lawsuits demonstrate that promotional emails with allegedly misleading subject lines may expose retailers to class-wide liability under state law — not just federal oversight.
• Federal law doesn't always preempt state protections. Courts appear to be signaling that Washington's CEMA can coexist with the federal CAN-SPAM Act, which may encourage similar state-level enforcement efforts in other jurisdictions.
• Claim deadlines matter. For the Cosequin settlement, missing the filing deadline likely means forfeiting any potential compensation. Eligible consumers should verify deadlines directly through the official settlement site.
