Cherry laurel or dog rose is a small deciduous tree native to central Europe. The leaves and roots in the bark of this plant contain an enzyme called aspergilloprunasin. Toxicity in dogs and cats is similar to cyanide toxicity. Prunasin, a glucoside of amygdalin, is produced in the seeds of the tree and is broken down by the enzyme glucosinolmycin. The resulting hydrogen cyanide (HCN), however, does not get broken down and accumulates in the blood stream. Dogs and cats that ingest cherry laurel may show sublethal signs of hydrogen cyanide toxicity, including muscle paralysis. If your pet came into contact with cherry laurel, they should immediately seek medical care for HCN
