Can Dogs Eat Hops?
✗ Toxic : Moderate Risk
From brewing. Causes rapid temperature increase, seizures.
Hops are highly toxic to dogs and should never be fed under any circumstances. Even small amounts can cause a dangerous spike in body temperature, leading to hyperthermia, severe muscle rigidity, seizures, and ultimately death. Dogs who consume hops require immediate emergency veterinary treatment. Symptoms can appear within 6-12 hours and include tremors, panting, rapid heartbeat, and seizures. Keep all brewing equipment, hop pellets, and spent brewing materials completely away from dogs. If ingestion is suspected, contact your vet or emergency clinic immediately.
Why Hops Should Be Avoided
Hops (Humulus lupulus) used in beer brewing cause a condition called malignant hyperthermia in dogs. Body temperature can spike to fatal levels very rapidly. Both fresh and dried hops are dangerous. Greyhounds and sighthound breeds appear especially susceptible.
What To Do If Your Dog Eats Hops
Treat as an emergency. Cool your dog with wet towels and seek immediate veterinary care.

Watch out: Owners assume hops are safe because they come from plants. Some may underestimate severity or delay seeking help. Others leave brewing equipment unattended where dogs can access it. Never assume recovery is possible without emergency treatment; hops toxicity has a high fatality rate.
