Is Rhubarb (leaves) toxic to dogs & cats?
Also known as: rhubarb leaves
🚑 What to do right after ingestion
Withhold food and see the vet for kidney and calcium assessment; even small amounts warrant checking.
Toxicity notes
Leaves are rich in oxalic acid — oral irritation, low calcium and kidney damage (linked to urinary stones).
Poisoning symptoms
- • Drooling
- • Vomiting
- • Mouth tremors
- • Weakness
- • Blood in urine / urination changes
Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.
FAQ
How much causes poisoning?
Leaves are rich in oxalic acid — oral irritation, low calcium and kidney damage (linked to urinary stones).
Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
