This guide explains whether hydrangeas are poisonous to dogs, what symptoms to look for, and how to keep your pets safe while enjoying these beautiful shrubs.

Are Hydrangeas Poisonous to Dogs?

Yes, hydrangeas are toxic to dogs. The leaves, flowers, and stems of the hydrangea plant contain a compound called cyanogenic glycosides, which can be harmful if ingested. While severe poisoning is rare, consuming parts of the plant can cause mild to moderate symptoms in dogs.

Why Are Hydrangeas Toxic to Dogs?
