Pets who chew or swallow certain plants can suffer symptoms such as vomiting, diarrhoea, drooling, mouth irritation, and, in severe cases, tremors or collapse.

Years, a company that makes dog food, said the most dangerous plants include daffodils, tulips, crocuses and lilies, with bulbs posing the biggest threat due to their concentrated toxins.

Darren Beale, CEO of Years, said: "Spring is brilliant for people, but it’s peak risk season for dogs that explore the world with their mouths.

"The tricky part is how normal it all looks.

"A dog can chew a bulb in the garden, lick vase water indoors, or mouth a houseplant while you’re on a call.

"If you think they’ve eaten something toxic, don’t wait it out.

"Get advice quickly and take it seriously."

If a dog has eaten something in the garden, pet owners are advised to check their mouth for plant material and call a vet urgently, providing details of what was eaten, how much and when.

A sample or photograph of the plant to help with identification is also suggested.

Vets do not recommend inducing vomiting unless specifically advised, as it can worsen some poisonings.

Preventative steps include fencing off beds with bulbs, keeping cut flowers and houseplants out of reach, and never leaving vase water accessible to pets.
