My dog ate Devil's Walking Stick - what should I do?

Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, lethargy, and potential oral inflammation.
Escalation note
The plant contains compounds that can irritate the digestive tract. Seek veterinary care if your dog shows signs of illness after exposure.
What to watch for
Most-to-least common signs in dogs: hypersalivation/drooling, vomiting, diarrhea, and skin or oral irritation around the muzzle. Severity is usually mild to moderate; the spines themselves can cause additional mechanical injury to the mouth.
Time window
Onset and duration are not well documented in the ASPCA entry; expect oral and GI signs within hours of ingestion in line with other irritant plants.
When to call the vet
Call your vet if drooling or vomiting persists more than a few hours, if your dog refuses food and water, if you see oral swelling, or if there is any visible bleeding from spine wounds.
What this means for your dog
Dogs that chew or bite this thorny shrub typically get a mouthful of irritation rather than a life-threatening dose. ASPCA lists Aralia spinosa as toxic to dogs because of its araliin content, but the most likely outcome from a curious nibble is mouth and stomach upset.
