Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, and potential abdominal discomfort.
Escalation note
While generally mild, ingestion can lead to digestive irritation. Consult a veterinarian if you are concerned about the amount consumed.
What to watch for
Most common with leaf ingestion: vomiting and diarrhea, especially after large amounts. With essential-oil exposure: drooling, weakness, ataxia, and possible CNS depression. Severity is usually mild for casual nibbling and moderate-to-severe for big ingestions or oil exposure.
Time window
GI signs from fresh mint usually appear within a few hours and resolve over 24–48 hours with supportive care. Specific timing isn't given by ASPCA; large or essential-oil ingestions can cause faster onset.
When to call the vet
Call your vet or ASPCA APCC (888-426-4435) if your dog ate a large quantity of mint, is vomiting repeatedly, has bloody diarrhea, or got into peppermint or any mint essential oil. A single leaf snatched from a planter, with no symptoms, can usually be watched at home.
What this means for your dog
Garden mint is on the ASPCA's toxic-to-dogs list, with essential oils as the toxic principle. The good news for dog owners: a leaf or two grabbed from a herb pot is unlikely to cause more than mild stomach upset. The risk scales with the amount eaten — a dog that demolishes a whole mint plant or licks up spilled mint essential oil is much more likely to need a vet.
