What temperature is safe for dogs? A simple UK guide

Elderly dogs like my girl Angel need extra help in hot and cold weather.

Dogs may have fur coats, but they can still feel the cold and heat just like humans. A dog’s comfort depends on many factors including breed, coat type, body fat, age, health and how used they are to different climates. While dogs naturally have a slightly higher body temperature than people, not all are equally protected against extreme weather.

In the UK, most dogs are comfortable in cool to mild temperatures (around 5–15°C), though smaller, short-haired, elderly, or unwell dogs may need extra warmth below 10°C. Very cold weather (below 5°C) increases risk, especially when combined with wind or rain, and prolonged exposure below freezing is unsafe for many breeds. On the other end of the scale, dogs usually cope well with 15–25°C, but temperatures above 25–27°C significantly raise the risk of heat stress and heatstroke.

Conditions like wind chill, wet weather, activity level and sun exposure can make temperatures feel far colder or hotter than the thermometer suggests. Practical steps such as providing warm bedding, using coats for vulnerable dogs, limiting walks in extreme weather, ensuring constant access to water, and watching for signs of distress (shivering, excessive panting, lethargy) are essential.

Ultimately, responsible dog ownership means adapting care to the individual dog and the unpredictable UK climate. When in doubt, err on the side of caution and seek veterinary advice to keep dogs safe, comfortable, and healthy year-round
