UK households with greenhouses are being urged to take action before Tuesday as an intense heatwave pushes temperatures up to 38°C. The Met Office has issued an amber heat warning covering large parts of England, with very hot conditions expected to continue through midweek. While gardeners focus on keeping plants watered, the Royal Kennel Club warns of a critical danger for dogs.
Dogs at Risk in Greenhouses
Dogs often wander freely in gardens during warm weather, especially when owners spend more time outside. The Royal Kennel Club is urging owners to ensure dogs cannot access greenhouses, even if doors are left open for ventilation. The organisation advises keeping doors securely shut or installing barriers such as pet-safe gates, mesh, or wire screens to prevent entry while allowing airflow.
"Keep your dog out of hot greenhouses. Even if the door is left open, these buildings tend to be incredibly warm," the Royal Kennel Club said.
Heatstroke: A Medical Emergency
Experts warn that dogs trapped inside greenhouses can quickly develop heatstroke, a serious medical emergency. According to the Royal Kennel Club, heatstroke can cause organ failure and become fatal if untreated. Research cited by the organisation found that one in seven dogs taken to vets with heatstroke dies.
All dogs can develop heatstroke, but some are more at risk: overweight dogs, older dogs, flat-faced breeds, larger breeds, dogs with long coats, and those with existing health conditions. Breeds commonly treated for heatstroke include French Bulldogs, Bulldogs, Pugs, Boxers, Golden Retrievers, Staffordshire Bull Terriers, and Cavalier King Charles Spaniels.
Preventive Measures and Signs of Heatstroke
Owners should ensure pets always have access to fresh drinking water and shaded areas in the garden. Paddling pools and gentle play with a hose can help dogs stay cool. Creating comfortable shaded spots away from greenhouses may discourage dogs from seeking shelter inside.
Early symptoms of heatstroke include heavy panting, excessive drooling, bright red gums, and unusual tiredness. More serious signs include vomiting, diarrhoea, disorientation, collapse, seizures, and loss of consciousness. If heatstroke is suspected, contact a vet immediately, move the dog to a cool shaded area, and begin safe cooling measures.
