My dog ate Prairie Milkweed — what to do
Step by step
- Take prairie milkweed 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 prairie milkweed — FAQ
Is prairie milkweed poisonous to dogs?
Yes — the ASPCA lists Prairie Milkweed (Asclepias hirtella) as toxic to dogs. As an Asclepias species, Prairie Milkweed contains cardenolide cardiac glycosides and milky latex throughout all plant parts, consistent with ASPCA's classification of Asclepias (milkweeds) as toxic to dogs and cats. Ingestion of any plant part may cause vomiting, weakness, cardiac arrhythmias, and respiratory depression. Consult a veterinarian immediately if ingestion is suspected.
How serious is it if my dog ate prairie milkweed?
Prairie Milkweed is toxic to dogs and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. As an Asclepias species, Prairie Milkweed contains cardenolide cardiac glycosides and milky latex throughout all plant parts, consistent with ASPCA's classification of Asclepias (milkweeds) as toxic to dogs and cats. Ingestion of any plant part may cause vomiting, weakness, cardiac arrhythmias, and respiratory depression. Consult a veterinarian immediately if ingestion is suspected. Any worsening or persistent symptoms warrant an immediate vet visit.
