Common questions

My dog ate a chicken dish with tarragon — should I worry?

The herb itself is a mild concern. Watch for upset stomach from the herb and the rich food, and call your vet if vomiting is repeated or the dog seems painful.

Is tarragon in a dog treat recipe safe?

Small culinary amounts are generally tolerated, but regular use is best avoided because estragole content raises long-term questions in animals.
