Garden hazards for pets: Five common causes of pet poisoning in the UK

Pet poisoning is more common than many UK pet owners realise, and the garden is one of the most frequent sources. From lawn treatments to toxic plants, everyday items can pose a serious risk to dogs and cats if ingested, inhaled or absorbed through the skin.

Understanding the most common garden hazards for pets can help prevent accidents and reduce the risk of emergency veterinary treatment.

1. Slug and snail pellets and dog poisoning

Slug and snail pellets remain one of the leading causes of dog poisoning in UK gardens. Many products contain metaldehyde, which is extremely toxic to dogs and can cause severe neurological symptoms within hours of exposure.

Even small amounts can lead to tremors, seizures and overheating, making this a frequent cause of emergency vet admissions.

Reducing risk:

• Avoid metaldehyde-based pellets entirely
• Use pet-safe pest control alternatives
• Store all garden treatments out of reach

2. Weedkiller, lawn feed and chemical exposure

Weedkillers, fertilisers and moss killers are common contributors to pet poisoning symptoms, particularly when pets walk across treated grass and later lick their paws.

Repeated exposure can cause vomiting, drooling, diarrhoea or skin irritation in both dogs and cats.

Reducing risk:

• Keep pets off lawns until products are fully dry
• Follow application instructions carefully
• Choose pet-safe or organic garden products

3. Compost bins and toxic food waste

Compost bins can contain moulds and toxins that pose a risk to dogs. Ingesting rotting food waste is a known cause of tremors and gastrointestinal illness.

Dogs are particularly vulnerable due to scavenging behaviour.

Reducing risk:

• Secure compost bins with tight-fitting lids
• Restrict access to garden waste areas
• Avoid composting cooked or mouldy food

4. Toxic plants for pets in UK gardens

Many popular plants are toxic to pets in the UK, including foxgloves, daffodils, azaleas and rhododendrons. Lilies are especially dangerous for cats, with even minimal exposure potentially causing kidney failure.

Plant toxicity is one of the most overlooked pet poisoning risks, particularly in spring and summer.

Reducing risk:

• Research plant safety before planting
• Remove highly toxic species
• Supervise pets that chew or dig

5. Antifreeze and garden chemicals

Antifreeze is extremely toxic to pets and is fatal in small amounts. It may be stored in sheds or garages, but leaks or spills can expose pets in garden areas.

Because antifreeze has a sweet taste, pets may ingest it unknowingly.

Reducing risk:

• Store chemicals in locked cupboards or sheds
• Clean spills immediately
• Never leave open containers unattended

What are the symptoms of pet poisoning?

Common pet poisoning symptoms include vomiting, drooling, tremors, lethargy, seizures and difficulty breathing. Some poisons act quickly, while others cause delayed symptoms.

If poisoning is suspected:

• Contact your vet immediately
• Do not induce vomiting unless advised
• Bring the product packaging where possible

Does pet insurance cover poisoning?

Treatment for pet poisoning can involve emergency consultations, blood tests, hospitalisation and intensive care. These costs can escalate rapidly, particularly for poisoning cases that require overnight monitoring.

Having pet insurance in the UK can help cover the cost of unexpected veterinary treatment, ensuring financial concerns do not delay urgent care.
