Yes, euonymus is toxic to dogs. Eating the showy seeds or chewing bark and leaves exposes a dog to alkaloids and heart-affecting glycosides.

Also known as: Spindle Tree, Strawberry Bush · Euonymus europaeus

What makes it toxic

Alkaloids and cardenolide-like compounds strongest in seeds and bark, causing GI irritation and, in significant ingestions, cardiac effects.

Warning signs to watch for

Vomiting, diarrhea, drooling and lethargy within hours; larger amounts can cause weakness, tremors and heartbeat irregularities.

What to do if your dog eats it

Take away the plant material, rinse the mouth and estimate the amount eaten. Call your vet promptly and treat abnormal heartbeat or collapse as an emergency.

Common questions

My dog ate the pink-orange capsules under our spindle tree — what now?

The seeds inside are the most toxic part. Check the mouth, call your vet or a poison hotline, and watch closely for vomiting or weakness.

Is euonymus safe as a hedge if my dog never chews it?

A dog that reliably ignores it is low risk, but fallen seed capsules each autumn create repeated exposure opportunities. Rake them up regularly.
