Dog owners are being warned to keep their pooches away from bluebells during their spring walks.
The plants contains scillarens, a chemical which can reduce a dog's heart rate and cause disorientation, vomiting, diarrhoea and lethargy.
As people head out for the bank holiday weekend, the Blue Cross is urging owners to remain vigilant and contact their vet as soon as possible if they believe their dog has ingested a toxic plant.
