What You Need to Know
Autumn crocus contains colchicine — the same compound used as medication for gout in humans but highly toxic to dogs at uncontrolled plant concentrations. It causes severe multi-organ failure affecting the kidneys, liver, and bone marrow. A particularly dangerous feature is delayed onset — symptoms may not appear for 2-3 days after ingestion, by which time significant organ damage has occurred. Spring crocus (Crocus sativus) is less toxic but still causes gastrointestinal upset. This is always a veterinary emergency.
