Is Sweet Potato Vine safe for dogs?

Sweet potato vine (Ipomoea batatas) is currently classified as potentially toxic to dogs, but that classification carries low confidence (0.4) and has been flagged as a likely labeler error that is under active curator review as of May 2026. Until the review is resolved, the safest approach is to prevent your dog from eating the foliage.

Specific symptom data for sweet potato vine ingestion in dogs is not currently documented — the underlying toxicity classification is under review and may reflect a mislabeling rather than a genuine hazard. If your dog has eaten the plant, watch for vomiting, diarrhea, or lethargy and contact your veterinarian if any signs appear.

Remove your dog from the plant, note roughly how much was eaten, and monitor for GI upset such as vomiting or lethargy. Because the toxicity status is unresolved and not fully established, call the ASPCA Animal Poison Control Center at (888) 426-4435 or your vet for guidance, particularly if a large amount was consumed.

Yes — ornamental sweet potato vine and the edible sweet potato are the same species (Ipomoea batatas), bred for decorative trailing foliage rather than root production. This botanical overlap is one reason the dog-toxicity classification is currently under curator review; the final safety determination is pending verification.
