Dog owners warned over ‘toxic’ plants you may have at home

Dog owners are being warned to inspect their houseplants this winter, as some of Britain’s most popular indoor varieties can prove toxic to dogs, , and pets don’t need to chew them to suffer.

Experts say the risk frequently stems from dropped leaves, plant sap and contaminated compost, which dogs may consume accidentally while grooming themselves or investigating their surroundings indoors.

Alyssa Ralph, Clinical Animal Behaviourist and Canine Nutritionist from fresh dog food brand Years.com, says numerous owners mistakenly believe plants pose no threat if their dog leaves them alone.

She explained: “Many owners assume that if their dog isn’t chewing a plant, there’s no danger. But toxicity can occur from licking sap or a fallen leaf, or even digging in soil where plant toxins have settled.”

The alert arrives as increasing numbers of people move plants inside during winter months to enhance their homes, raising the likelihood of accidental contact – especially for puppies, restless dogs and pets confined indoors for extended periods.

Ralph highlights some of the most frequently owned poisonous plants, including:

• Lilies – Extremely dangerous; ingestion can cause severe poisoning. Even the pollen can fall onto your dog’s coat, which can then be licked as they groom themselves and cause irritation.
• Aloe vera – The white sap can trigger vomiting, diarrhoea and lethargy.
• Ivy – Toxic compounds can be found in both leaves and berries.
• Peace lilies – Can cause oral irritation and digestive distress Snake plants – Mild to moderate toxicity that can cause drooling, vomiting and lethargy.

Ms Ralph cautioned that these are commonplace household plants.

She said: “These aren’t rare or exotic plants. They’re the ones people already have in their living rooms and kitchens.”

Why winter increases the risk

Pet specialists caution that the colder months create a “perfect storm” for plant-related incidents:

• Dogs spend more time indoors, heightening exposure.
• Plants are frequently relocated to ground level or lower surfaces for better light.
• Dry air from central heating causes leaves to drop, making fallen foliage more accessible for consumption.
• Puppies and under-stimulated dogs are more prone to digging in plant compost, due to curiosity and boredom coupled with greater exposure.

Signs of plant poisoning can be mild and are frequently confused with minor digestive issues. Initial indicators may include drooling, vomiting, diarrhoea, pawing at the mouth, lethargy or decreased appetite.

To minimise the risk, owners are recommended to position toxic plants entirely beyond reach, remove dropped leaves immediately and steer clear of ground-level plants in households with puppies or curious dogs.

Ms Ralph said insufficient knowledge is frequently the primary concern. She s:aid “With houseplants being an ever-more popular addition to many homes, pet-proofing advice hasn’t kept pace with modern living. The danger isn’t negligence – it’s lack of awareness.”
