My dog chewed on a hydrangea flower but didn’t eat any—should I be worried about toxicity anyway?

This afternoon while in the garden, my dog got hold of a hydrangea flower and chewed on it a bit but didn't swallow any. I’ve read that these plants can be toxic to dogs. Should I be worried about any potential toxicity from just chewing on the flowers or is he likely to be okay?

Answer

Your dog chewed on a hydrangea flower, which can be mildly toxic to dogs. However, if he did not swallow any part of it, the risk of toxicity is low, and he is likely to be okay.

  • Hydrangea plants contain cyanogenic glycosides, which can be toxic if ingested in large amounts.
  • Since your dog only chewed and did not swallow, the chance of significant harm is minimal.
  • Monitor for any symptoms, such as vomiting or diarrhea, and contact a vet if they occur.

Hydrangeas contain compounds that can release cyanide when metabolized, but toxicity is rare and generally only occurs if large amounts are consumed. It's always wise to monitor your dog for any signs of illness, such as vomiting or diarrhea, over the next 24 hours. If symptoms like these develop, it would be best to consult a vet for advice tailored to your dog's situation.
