Safety status
What this means for your dog
Dogs can get sick from chewing yarrow, but it is rarely a true emergency. ASPCA lists yarrow as toxic to dogs because of its glycoalkaloids, monoterpenes, and sesquiterpene lactones, and the typical picture is gastrointestinal upset rather than organ damage.
What to watch for
Most-common signs are vomiting, diarrhea, drooling, and loss of appetite. Some dogs also show colic-style abdominal discomfort, depression, or skin irritation (dermatitis) where the plant contacted the skin.
Time window
Onset is typically within a few hours of ingestion. Most dogs recover within 24–48 hours with supportive care; ASPCA notes yarrow is not organ-toxic, so persistent signs beyond that window warrant a vet recheck.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) if your dog is vomiting more than once or twice, has bloody or persistent diarrhea, won't eat or drink for more than a few hours, or seems unusually depressed or wobbly. Small or young dogs and any dog that ate a large amount should be evaluated promptly.
First aid at home
Gently wipe out your dog's mouth with a damp cloth to remove any plant residue and offer fresh water. Do not induce vomiting at home. Call your veterinarian or the ASPCA APCC at (888) 426-4435 before giving any treatment.
