Toxicity to pets

Hops flowers are used in the fermentation process of brewing beer. After fermentation the used hops are discarded. Ingestion of used hops by dogs can result in rapid onset, life-threatening high fever with clinical signs of panting, racing heart rate, vomiting, seizure, and death. Any breed or mixed-breed of dog may be affected, but breeds predisposed to high fever disorder including Greyhound, Labrador Retriever, Saint Bernard, Pointer breeds, Doberman, Border Collie, and American Cocker Spaniel are at higher risk for hops poisoning.
