Hops Toxic?

Hops are highly toxic to dogs, particularly sighthounds and Golden Retrievers, with ingestion potentially leading to fatal outcomes.
Specific toxic compounds and mechanism of action for hops poisoning remain unconfirmed by leading toxicology authorities.
Rapidly progressive, life-threatening high fever is the primary hallmark symptom of hops poisoning in affected dogs.

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Induce vomiting immediately if hops ingestion occurred within the past 2 hours and the affected dog is conscious and not seizing.
- • Administer activated charcoal to absorb unabsorbed residual toxins once vomiting is successfully completed.
- • Continuously monitor core body temperature, apply active cooling measures (cool water sprays, fans) if temperature exceeds 39°C (102.2°F).
Contact Vet Immediately
- • Any confirmed or suspected ingestion of hops by a dog, regardless of quantity consumed.
- • Onset of symptoms including excessive panting, fever, rapid heart rate, disorientation or seizures post exposure.
- • If the exposed animal is a sighthound or Golden Retriever, even if no symptoms appear immediately after ingestion.
Prevention
- • Store all hops products (including home brewing supplies, hop pellets, spent brewing hops) in sealed, pet-proof containers out of reach of dogs.
- • Never feed any food, treats or homemade products containing hops to dogs of any breed.
- • Dispose of used brewing hops in secured outdoor waste bins that pets cannot access.
Treatment & Prognosis
- • Perform immediate gastrointestinal decontamination including emesis, activated charcoal administration, or gastric lavage for recent large ingestions.
- • Administer dantrolene at an initial dose of 2-3 mg/kg intravenously or 3.5 mg/kg orally, followed by 3.5 mg/kg every 12 hours as clinically required.
- • Provide supportive care including continuous temperature monitoring, anti-seizure medication, intravenous fluid therapy, and cardiac monitoring until symptoms fully resolve.
