Is Common Poppy toxic to dogs?

Papaver rhoeas

Toxic to dogs

Yes — common poppy is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Papaver rhoeas is listed as toxic to dogs, cats, and horses. It contains isoquinoline alkaloids including rhoeadine, coptisine, and allotropine, which act as CNS depressants and produce opioid-like toxicity. Ingestion can cause sedation, ataxia, pinpoint pupils (dogs) or dilated pupils (cats), drooling, vomiting, respiratory depression, and in severe cases coma. All parts of the plant — including the green stems, leaves, sap, and unripe seed heads — are considered toxic; the milky sap is the most potent. Contact the ASPCA Animal Poison Control Center (888-426-4435) if ingestion is suspected.
