Is Hart's Pennyroyal toxic to dogs?
Mentha cervina
Mildly. The ASPCA lists hart's pennyroyal 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. Mentha cervina (Hart's Pennyroyal) is not individually listed by the ASPCA. The Mentha genus is generally considered non-toxic to dogs and cats at small doses, but concentrated mint oils (pulegone) in related pennyroyal species (especially Mentha pulegium) are hepatotoxic in cats and dogs. As a pennyroyal-type mint of uncertain oil profile, caution is warranted: keep away from pets and do not administer as an essential oil or extract to animals. Consult a veterinarian before allowing pet access.
