Safety status
What this means for your dog
Dogs usually tolerate a small accidental nibble of garden chamomile with only mild stomach upset, but ASPCA still lists Anthemis nobilis as toxic to dogs. The bigger risks are larger ingestions (a raided tea bag, a planter pulled apart in the yard) and ongoing supplementation, which the ASPCA links to bleeding tendencies.
What to watch for
Most common: vomiting, diarrhea, and reduced appetite. Watch also for excessive drooling, contact dermatitis or itchy red skin where the plant touched, and allergic reactions including facial swelling. With long-term exposure, ASPCA flags bleeding tendencies — bruising, prolonged bleeding from minor cuts, or unexplained nosebleeds — as a more serious sign.
Time window
Mild GI signs usually appear within hours of ingestion and resolve within roughly 24 hours with supportive care. Skin reactions can be immediate or delayed. Bleeding-tendency effects are associated with chronic, repeated exposure rather than a one-time nibble.
When to call the vet
Call the vet if vomiting or diarrhea is persistent or contains blood, if your dog seems lethargic or off food for more than 12 hours, if there is facial swelling or trouble breathing (possible allergic reaction), or if you see any sign of abnormal bleeding or bruising. Call right away if a dog ate a chamomile-containing essential oil, tincture, or a flavored tea bag (which may also contain xylitol or caffeine).
