Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, and abdominal discomfort.
Escalation note
Ingestion may lead to digestive irritation. Monitor your pet closely and consult a veterinarian if symptoms occur.
What to watch for
Mild vomiting and diarrhea are the typical signs. Also watch for drooling, decreased appetite, and minor lethargy. Larger ingestions or dogs with sensitive stomachs may show more pronounced or longer-lasting GI signs.
Time window
Onset is not specifically documented in the cited sources. For similar essential-oil plants, mild GI signs typically begin within a few hours of ingestion and resolve within 24–48 hours with supportive care.
When to call the vet
Call your vet if vomiting or diarrhea persists beyond a few hours, if your dog seems weak, dehydrated, or cannot keep water down, or if you see any neurological signs such as tremors or unsteadiness. ASPCA Poison Control: (888) 426-4435.
What this means for your dog
Tarragon is toxic to dogs per the ASPCA, with essential oils as the toxic principle. Reactions are usually limited to mild GI upset rather than serious systemic illness, so a single nibble of garden tarragon rarely turns into an emergency — but it is not a safe treat to encourage either.
