What to do if your pet ate it
Contact your vet or a poison line right away, report how much wisteria was eaten and your pet's weight, and keep any packaging or leftovers. Do not induce vomiting unless your vet tells you to.
Signs to watch for
- Vomiting and diarrhoea
- Lethargy and weakness
- Loss of appetite
- Severe: tremors, breathing trouble, collapse
If your pet shows vomiting, lethargy or any unusual behaviour after eating wisteria, go to the nearest emergency vet immediately.
Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Why these cautions matter
Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
Frequently asked questions
Can dogs eat wisteria?
NO — do not feed. Wisteria vines, flowers and seed pods have toxic lectins and cyanogenic glycosides. When a dog or cat chews the foliage, they may develop oral burning, vomiting, diarrhea and lethargy. Severe cases can lead to low blood pressure and collapse.
What if my dog already ate wisteria?
Call your vet or a poison line now with the amount of wisteria eaten and your dog's weight, and do not induce vomiting unless a vet tells you to. If wisteria was eaten and you then see vomiting, lethargy, tremors or breathing changes, go straight to the nearest emergency clinic.
Is there a safe amount of wisteria for dogs?
There is no accepted safe dose of wisteria for dogs; it is classed as toxic or dangerous, and reactions vary with the individual animal, so it is not something to feed at any amount.
How often can dogs have wisteria?
wisteria is not something to feed at any interval; it stays off the menu entirely.
What are safer treats than wisteria for dogs?
Pick from the safe list instead — Cooked eggs or Green beans carry none of the risk that wisteria does, and they work better as an everyday treat.
