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?
The cyanogenic glycosides found in hydrangeas release cyanide when metabolized. Although the concentration of these compounds is relatively low, ingestion can still cause digestive upset and discomfort in dogs.
