What makes it toxic

Irisin and other iridoid glycosides in rhizomes, roots and foliage. They inflame the GI tract and can depress the nervous system in significant doses.

Warning signs to watch for

Drooling, vomiting, diarrhea, lethargy and abdominal discomfort within hours. Larger rhizome meals can leave a dog visibly dull.

What to do if your dog eats it

Take material away, offer water and call your vet, especially after rhizome exposure. Dogs that dig iris beds are the classic case — supportive care resolves most.
