A proposed class action claims certain Doggie Dailies-brand glucosamine supplements are “a sham” in that their active ingredients do not improve joint function in dogs.
According to the lawsuit, Compana Pet Brands has falsely advertised the Doggie Dailies supplements—including Advanced Hip & Joint Supplement for Dogs; 5-in-1 Multivitamin; Senior Essentials Advanced Hip & Joint; and Senior Essentials 10-in-1 Senior Multivitamin—as able to help improve dogs’ joint health. The suit alleges, however, that the products’ key ingredients, glucosamine hydrochloride and chondroitin sulfate, have not been shown to improve dogs’ joint function.
Per the case, Compana “is undoubtedly aware” that studies have shown glucosamine supplements to be ineffective in improving joint health yet “continues to sell them to unsuspecting consumers.”
“To the extent that Defendant’s representations unequivocally state that the Supplements ‘contain glucosamine for joint health’ and ‘promote[] healthy hips, joints, and ligaments’ when in fact the products are ineffective, the labeling statements at issue intend to mislead unsuspecting customers who are looking for joint supplements to help reduce and treat canine arthritis symptoms,” the lawsuit reads.
According to the suit, the Doggie Dailies glucosamine supplements are specifically advertised, both on their labels and on the defendant’s website, as able to support and improve joint function in dogs. These representations are based on the fact that the supplements contain active ingredients glucosamine hydrochloride and chondroitin sulfate, the case relays.
The lawsuit alleges, however, that “[d]ecades of studies and peer-reviewed tests” have shown that glucosamine and chondroitin supplements do not improve joint function in dogs. For example, the case says, a 2003 study found that dogs treated with a glucosamine and chondroitin supplement “showed no significant improvements” in their gait, joint mobility, pain and discomfort, lameness and activity. Similarly, a 2017 study found that a glucosamine and chondroitin supplement “did not have a beneficial treatment effect” as compared to a placebo, the suit relays.
Moreover, several other publications have noted that the efficacy of glucosamine and chondroitin supplements for treating joint problems in dogs is “uncertain” and “has yet to be determined,” the lawsuit says.
According to the case, the defendant’s representations that the Doggie Dailies products can help improve dogs’ joint function are therefore false and misleading. The lawsuit argues that consumers would not have purchased the products, or would have paid less for them, had they known the supplements were ineffective at improving dogs’ joint health.
The case looks to cover anyone who purchased the Doggie Dailies products mentioned on this page in California.
