I think we go through this every year, so here is my two cents worth! My dog died from ingesting FRESH hops from my vines! The vet did a necropsy and found them in her stomach and ruled it the cause of death due to malignant hyperthermia. She was a border collie, lab mix. It can happen to any dog!

Here is some reading for everyone.

Hops, a plant used in making beer, can cause malignant hyperthermia in dogs, usually with fatal results. Certain breeds, such as Greyhounds, seem particularly sensitive to hop toxicity, but hops should be kept away from all dogs. Even small amounts of hops can trigger a potentially deadly reaction, even if the hops are "spent" after use in brewing.


Unbeknownst to most vets, at least eight cases of hop toxicity in dogs have been recorded by the National Animal Poison Control Center at the University of Illinois in Urbana, IL. Seven of the dogs have been Greyhounds, with one remaining case being a Labrador Retriever cross.



This is a warning that the ingestion of used hops from home brewing can be fatal to dogs. Some breeds have a toxic reaction that triggers the onset of Malignant Hyperthermia (MH), a life threatening condition in which the body uncontrollably overheats. Do not mulch your used hops - seal them in a container and dispose of in the trash!


A study conducted by the National Animal Poison Control Center, University of Illinois in Urbana in 1995 showed this to be true. Of the eight dogs, seven were Greyhounds, one was a Labrador Retriever, all cases were fatal. The dogs had ingested spent hops. Dogs are attracted to the sweet wort covering the hops.







This might make a good sticky!

chemman14: Rather than argue about the nuances of Malignant Hyperthermia can we all just agree to recommend that hops be kept away from dogs?

thantos: Sorry for your loss. Thanks for the resources.
