Pet emergency

My dog ate Quince — what to do

Step by step

  1. Take quince away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet, or a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. Follow their advice.
  5. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.

My dog ate quince — FAQ

Is quince poisonous to dogs?

Yes — Quince (Cydonia oblonga) is regarded as mildly toxic to dogs, based on genus- and family-level toxicity data. Cydonia oblonga is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its pet status is not authoritatively classified. As a member of the rose family (Maloideae), the seeds and leaves contain trace cyanogenic compounds (amygdalin) that can release small amounts of cyanide if chewed in quantity. Treat with caution and verify with a vet before assuming it is safe around pets.

How serious is it if my dog ate quince?

Quince 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. Cydonia oblonga is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its pet status is not authoritatively classified. As a member of the rose family (Maloideae), the seeds and leaves contain trace cyanogenic compounds (amygdalin) that can release small amounts of cyanide if chewed in quantity. Treat with caution and verify with a vet before assuming it is safe around pets. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.

How do I stop this happening again?

Keep quince well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
