Is Milkweed safe for dogs?

Yes, milkweed (Asclepias species) is toxic to dogs. All parts of the plant contain cardiac glycosides that can affect the cardiovascular and nervous systems, making prompt veterinary care essential if your dog has eaten any part of it.

Early signs include drooling, vomiting, abdominal pain, profound depression, weakness, anorexia, and diarrhea. As poisoning progresses, dogs may develop seizures, difficulty breathing, a rapid weak pulse, dilated pupils, and in severe cases kidney or liver failure, coma, or respiratory paralysis. ASPCA reports onset within 2 hours of ingestion, with signs potentially persisting 4–5 days.

Remove your dog from the plant and clear any leaves or milky sap from the mouth, then call your vet, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661 immediately — do not wait for symptoms to appear. Do NOT induce vomiting unless explicitly directed by a vet or poison helpline, as they may prefer activated charcoal or controlled emesis depending on timing. Bring a piece of the plant or a photo to the clinic for identification.

Signs can appear within 2 hours of ingestion. Most dogs that receive prompt treatment recover within a day or two in a calm, supportive environment, according to Pet Poison Helpline. Treatment may include activated charcoal, induced emesis, or digoxin-specific antibodies depending on the timing of ingestion and the Asclepias species involved — early intervention is the key factor in outcome.
