What happens if my dog eats a chrysanthemum?

Expect possible gastrointestinal upset: vomiting, diarrhea, and hypersalivation. Larger amounts can cause incoordination (wobbliness), and skin contact may cause dermatitis. Signs are typically mild, but contact your veterinarian or ASPCA Animal Poison Control (888-426-4435) if your dog ate a significant amount or shows symptoms.

Are mums toxic to cats too?

Yes. The ASPCA lists chrysanthemums as toxic to cats and horses as well as dogs, due to the same toxic principles (sesquiterpene lactones and pyrethrins). Cats can be particularly sensitive to pyrethrins, so keep mums out of reach of all pets.
