Short answer

Coriander seeds are safe, but watch for 12-24 hours in case of rare allergies or mild stomach upset. Signs like vomiting or diarrhea would appear within this window. If your dog shows no symptoms after a day, no further action is needed. For severe reactions, your vet may run blood tests to check organ function.
