It's been called a miracle drug for dogs suffering from arthritis. But now, the U.S. Food and Drug Administration is raising alarms about Librela, warning veterinarians of potential adverse effects, including death, in some dogs receiving the treatment.

A Kane In Your Corner investigation uncovers government records that reveal over 8,000 complaints to the FDA from dog owners about adverse reactions following Librela injections. The FDA's recent letter to veterinarians highlighted ataxia, a loss of muscle control, as one of the most frequent side effects, with some cases resulting in death.
