My dog ate Bitter Vetch — what to do
Step by step
- Take bitter vetch away and remove any plant material from your dog's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My dog ate bitter vetch — FAQ
Is bitter vetch poisonous to dogs?
Yes — the ASPCA lists Bitter Vetch (Lathyrus linifolius) as mildly toxic to dogs. The Lathyrus genus contains toxic amino acids (lathyrogens, including beta-aminopropionitrile/BAPN) concentrated especially in the seeds. ASPCA lists Lathyrus latifolius (perennial sweet pea) as non-toxic to cats and dogs but toxic to horses. L. linifolius is expected to share this profile; large seed ingestion could cause gastrointestinal upset or, in horses, neurological signs (lathyrism). Pets should be prevented from grazing the seeds.
How serious is it if my dog ate bitter vetch?
Bitter Vetch is mildly toxic, so most dogs get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your dog ate a lot or symptoms persist.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. The Lathyrus genus contains toxic amino acids (lathyrogens, including beta-aminopropionitrile/BAPN) concentrated especially in the seeds. ASPCA lists Lathyrus latifolius (perennial sweet pea) as non-toxic to cats and dogs but toxic to horses. L. linifolius is expected to share this profile; large seed ingestion could cause gastrointestinal upset or, in horses, neurological signs (lathyrism). Pets should be prevented from grazing the seeds. Any worsening or persistent symptoms warrant an immediate vet visit.
Should I make my dog vomit?
No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.
How do I stop this happening again?
Keep bitter vetch well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
