Safety status
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.
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.

Questions about Mint
Is mint toxic to dogs?
Mint (Mentha sp.) is classified as potentially toxic to dogs. The essential oils in mint can cause gastrointestinal distress, though a single leaf snatched from a planter typically causes only mild or no symptoms. Larger quantities or exposure to concentrated mint essential oils carry a higher risk of more serious effects.
What symptoms will my dog show after eating mint?
After eating mint, dogs most commonly show vomiting, diarrhea, and abdominal discomfort. Exposure to peppermint or mint essential oils can additionally cause drooling, weakness, unsteady walking (ataxia), and possible CNS depression. GI signs from fresh mint leaves usually appear within a few hours and resolve over 24–48 hours with supportive care.
When should I call the vet if my dog ate mint?
Call your vet or the ASPCA Animal Poison Control Center at (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 with no symptoms can generally be monitored at home.
Is mint essential oil more dangerous to dogs than fresh mint leaves?
Yes — mint essential oil is significantly more concentrated than fresh leaves and poses a greater risk. While fresh mint leaf ingestion usually causes mild GI upset, essential-oil exposure can cause faster-onset and more severe effects including drooling, weakness, ataxia, and CNS depression, and warrants an immediate call to your vet or the ASPCA APCC at (888) 426-4435.
