Pet ingestion lookup
My dog ate Dock - what should I do?
Rumex sp.
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Oral irritation, excessive drooling, vomiting, and difficulty swallowing or pawing at the mouth.
Escalation note
While usually not life-threatening, the irritation can be distressing. Consult a veterinarian if you suspect your dog has consumed significant amounts of the plant.
What to watch for
Most-to-least common signs in dogs: salivation/drooling, gastrointestinal upset, and tremors after a larger ingestion. Acute kidney injury is described as rare but is the worst-case outcome to remain alert for.
Time window
ASPCA does not document a specific onset window; signs from soluble oxalate ingestions in dogs are generally reported within hours of exposure.
When to call the vet
Call your vet right away if you see tremors, weakness, or unsteady walking, or if your dog ate a large quantity. For mild drooling alone, monitor and call if it persists past a few hours or your dog refuses food.
What this means for your dog
Dogs that graze on a patch of dock are more likely than cats to swallow a meaningful quantity. ASPCA lists the plant as toxic to dogs via soluble calcium oxalates and identifies tremors and salivation as the main signs, with kidney failure described as rare.
