Cherry Laurel and Dogs — Toxicity Guide
Cherry laurel (Prunus laurocerasus) is a common evergreen hedge and garden plant across the UK. Its leaves, seeds, and cut or wilted hedge material can contain cyanogenic glycosides. When plant material is chewed, these compounds can release hydrogen cyanide, so hedge clippings should never be left where dogs can eat them.
Which Parts of Cherry Laurel Are Dangerous?
The main concern is chewed or crushed plant material, especially leaves and seeds. Cherry laurel is also risky after hedge trimming because fallen leaves and branches can wilt, dry, and remain accessible in garden waste. The risk depends on the part eaten, how much was consumed, whether it was chewed, and the dog's size, but there is no reliable safe home dose.
Cherry laurel is part of the Prunus family. Other Prunus plants, including cherry, plum, peach, apricot, and damson, can also pose a cyanogenic-glycoside risk when seeds or stones are chewed and swallowed.
Signs of Cherry Laurel Exposure in Dogs
Dogs may develop drooling, vomiting, diarrhoea, abdominal discomfort, or reduced appetite after eating plant material. Cyanide poisoning is uncommon in dogs and cats but can be severe: frothing at the mouth, unusually large pupils, breathing difficulty, weakness, collapse, or sudden death require emergency veterinary treatment.
Signs can appear quickly or may be delayed. A dog that seems well after eating cherry laurel still needs prompt advice, particularly after eating leaves, seeds, or a large amount of hedge trimmings.
What to Do If Your Dog Eats Cherry Laurel
Contact your vet or an emergency veterinary practice immediately and explain which part of the plant was eaten, approximately how much, when it happened, and whether it was chewed. Take a clear photograph or a sample of the plant if this can be done safely. In the UK, the Animal PoisonLine can provide telephone triage advice on 01202 509 000 (charges apply).
Do not induce vomiting or give home remedies unless a veterinary professional specifically tells you to. If your dog is struggling to breathe, collapsing, having seizures, or showing severe weakness, go straight to an emergency vet.
Preventing Cherry Laurel Poisoning
Keep dogs away while cherry laurel hedges are being cut, collect every leaf and branch, and secure garden waste before allowing pets back into the area. Do not put accessible trimmings in an open compost heap. If replacing a hedge, ask a qualified local nursery or landscaper about dog-safe alternatives, and supervise dogs around any unfamiliar plant until it has been identified.
