Pet emergency
My dog ate Brussels sprouts — what to do
Step by step
- Take brussels sprouts 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 brussels sprouts — FAQ
Is brussels sprouts poisonous to dogs?
Yes — the ASPCA lists Brussels sprouts (Brassica oleracea var. gemmifera) as mildly toxic to dogs. ASPCA-equivalent risk: Brassica oleracea contains isothiocyanates; small amounts are safe but large quantities cause GI upset and gas in cats and dogs.
How serious is it if my dog ate brussels sprouts?
Brussels sprouts 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. ASPCA-equivalent risk: Brassica oleracea contains isothiocyanates; small amounts are safe but large quantities cause GI upset and gas in cats and dogs. 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 brussels sprouts well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
