Is Muster-John-Henry toxic to dogs?

Tagetes minuta

Mildly toxic to dogs

Mildly. The ASPCA lists muster-john-henry as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Tagetes species are listed by the ASPCA as mildly toxic to dogs and cats due to thiophene compounds in the foliage and sap. T. minuta contains high concentrations of essential oils (including dihydrotagetone and ocimenone) that may cause gastrointestinal upset or contact dermatitis in pets and sensitive humans. The plant is not individually listed by ASPCA but falls under the Tagetes genus advisory.
