Is Purple toadflax toxic to dogs?

Linaria purpurea

Mildly toxic to dogs

Mildly. The ASPCA lists purple toadflax 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. Linaria purpurea is not individually listed by the ASPCA. Like other Linaria species (Plantaginaceae), it contains iridoid glycosides that may cause mild gastrointestinal upset if consumed in significant quantities by pets or humans. Not considered severely toxic, but consumption should be discouraged.

What to do if your dog ate purple toadflax

  1. Remove any plant material from your dog's mouth and move purple toadflax out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of purple toadflax to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten purple toadflax, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
