Is Salsify 'Mammoth Sandwich Island' toxic to dogs?

Mildly. The ASPCA lists salsify 'mammoth sandwich island' 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. Tragopogon porrifolius is not individually listed in the ASPCA toxic/non-toxic plant database, so its pet status is treated as uncertain; the root and young leaves are a long-established human food and no specific animal toxicity is documented, but without ASPCA grounding it should be treated with caution and verified with a vet before feeding to pets.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to salsify 'mammoth sandwich island'.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
