Are Newfoundlands good in hot weather?
Newfoundlands were built for cold climates, so a hot spell asks for real care. They can be kept comfortable, but not by accident.
How Newfoundlands handle the heat
The cooling problem
Newfoundlands carry a dense double coat evolved to trap warmth. It insulates against heat as well as cold to a point, but in high temperatures it works against them, and humidity makes it worse. The coat is a heat store they cannot simply shed on a hot day.
Practical summer management
Shift walks to early morning and late evening, and skip them entirely on the hottest days. Carry water on every outing, provide deep shade in the garden, and give access to cool floors indoors. The pavement test is simple: press the back of your hand to the ground for seven seconds, and if it is too hot for your hand it is too hot for paws.
Never shave a double coat to "cool the dog down". It removes the insulating layer that also blocks heat and can leave the skin exposed to sunburn. Regular brushing to clear dead undercoat is the right approach.
Exercise in warm weather
Newfoundlands have moderate exercise needs, which makes summer easier to manage. It is straightforward to shift their activity into the cooler hours without leaving them under-exercised.
What temperature is too hot?
There is no single cutoff, because humidity, age, weight, and coat all matter. As a guide, take extra care above 20C and treat anything above 25C as high risk for a heavy-coated breed like this. When in doubt, keep them home and cool.
Personality and summer walks
A bear-sized dog with the temperament of a saint. Devoted to children, drools on everything, and sheds like a winter storm.
A gentle temperament tends to slow down sensibly in hot weather, resting rather than pushing through discomfort the way a more driven dog often will. Patient dogs cope well with a slower, more restricted routine on a hot day, waiting out the worst of the heat indoors without becoming restless. A devoted dog will keep following its owner around a sunny garden rather than choosing the shade on its own, so redirecting it toward a cooler spot makes a real difference.
Heat, training and behaviour
Teaching a dog to settle in the shade
Newfoundlands generally learn a reliable "settle" or "go to your bed" command without much difficulty, which is useful on a hot day when the goal is to keep the dog resting in a cool spot rather than pacing about.
Barking and restlessness in a heatwave
Newfoundlands rarely bark much, so discomfort in hot weather is more likely to show as excessive panting or reluctance to move than as noise.
Family and other pets in a heatwave
Newfoundlands generally do well around children, though hot weather adds a job for parents: making sure excitable play with kids in the garden does not run on longer than the dog can safely handle. They typically share a house with a cat without issue, and both species tend to gravitate to the same cool spots during a heatwave.
Cost and ageing in hot weather
Newfoundlands typically live 8 to 10 years, and older dogs of any breed regulate heat less efficiently than a fit adult, so senior newfoundlands need shorter, cooler outings and closer watching during a heatwave. Insurance for a Newfoundland in the UK typically costs about £65 to £140 a month, and heatstroke is exactly the kind of sudden, serious vet visit that cover exists for. A Newfoundland puppy, usually priced around £1200 to £2500, overheats more easily than an adult dog as well, since puppies have less developed temperature regulation and tire without always showing it.
