Autumn Crocus is among the most dangerous plants a dog can eat. Every part contains colchicine — concentrated most heavily in the seeds and bulbs — and ingestion can lead to multi-organ failure. This is an emergency, not a wait-and-see.
Early signs are severe drooling, bloody vomiting, and bloody diarrhea. Within hours to days, signs can progress to shock, liver and kidney damage, central-nervous-system effects including seizures, bone-marrow suppression, and respiratory failure. Even a small ingestion can be fatal.
Clinical signs can be seen within hours of ingestion but may also be delayed for days; the delayed onset is part of what makes colchicine poisoning so dangerous.
Call immediately. ASPCA Poison Control: (888) 426-4435. Pet Poison Helpline: (855) 764-7661. Then drive to the nearest emergency vet — don't wait for symptoms to appear.
