CAN DOGS EAT HOPS?
Hops used in home brewing cause malignant hyperthermia in dogs — a rapid, uncontrolled rise in body temperature that can be fatal without immediate intervention.
Can Dogs Eat Hops?
Why?
Hops (Humulus lupulus) contain compounds — including resins, essential oils, and alpha and beta acids — that trigger malignant hyperthermia in dogs. This is a syndrome of uncontrolled muscle metabolism that causes body temperature to spike to 106–108°F or higher. Without treatment, this causes organ failure and death rapidly.
Home brewing has made hops more accessible as a household item. Spent hops (used in brewing) retain their toxicity. Dogs who get into a homebrew setup, spent hops compost, or dried hops pellets are at serious risk.
How much is dangerous?
Even a small amount (a handful of dried hops pellets) can trigger malignant hyperthermia.
What are the symptoms?
- hyperthermia (body temp >104°F)
- panting aggressively
- anxious or restless behavior
- muscle tremors
- rapid heart rate
- vomiting
- seizures
- organ failure
What should I do?
Emergency veterinary care immediately. The dog's body temperature must be brought down while underlying toxicity is treated. This is a time-critical emergency.
Frequently asked questions.
Are spent hops still toxic?
Yes. Spent hops (used in brewing) retain their toxicity and are frequently composted — keep dogs away from homebrew waste.
Can dogs be around beer being brewed?
Keep dogs away from the entire brewing process and all hop-containing ingredients.
