Yes, cassia is toxic to dogs. Eating the leaves, flowers or especially the pods causes violent laxative effects and gut inflammation.

Also known as: Golden Shower Tree, Senna · Cassia spp.

What makes it toxic

Anthraquinone glycosides and saponins in the foliage, flowers, pods and seeds, which act as powerful stimulant laxatives and gut irritants.

Warning signs to watch for

Vomiting, repeated watery diarrhea, abdominal cramping, drooling and weakness within hours. Heavy pod consumption risks serious dehydration.

What to do if your dog eats it

Take away the plant material, encourage drinking and monitor stool. Call your vet if diarrhea repeats or the dog becomes quiet; treat severe diarrhea as urgent.

Common questions

My dog ate cassia pods under the tree — is that bad?

Pods are the most toxic part. Expect significant diarrhea and call your vet early, especially for a small dog, since dehydration develops fast.

Will one flower cause problems?

A single flower usually causes nothing or mild loose stool. Larger amounts, or any pod, deserve closer monitoring.
