Be careful when the temperature drops below 45 degrees Fahrenheit (around 7 degrees Celsius). It's not safe for small or medium dogs with fine fur to be outside, but large dogs with thicker fur are probably OK. Once the temperature drops below 20° F, dogs can begin to develop cold-related health problems, such as frostbite and hypothermia. You should limit outdoor time and monitor your puppy for behaviors such as chills and slowing down.
In general, most dogs can tolerate temperatures up to 40 degrees. Think of 45 degrees Fahrenheit or around 7.2 degrees Celsius as your cut-off point for extended periods of time outdoors. At around 12 to 15 degrees, most pets will probably be quite safe. At 10 degrees, you should watch for them, as it can be potentially unsafe depending on your age, general health, and race.
Seven degrees indicate that there is certainly a potential danger, and at four degrees the temperature is life-threatening. Animals should not have extended periods outdoors when temperatures are as low as this. Adelaide is currently experiencing overnight lows of 4 -5 degrees and pets should not be outdoors for long during these conditions. In general, if the outside temperature is 45° F (7.2° C) or higher, protection from the cold is not a concern.
Once the thermometer begins to lower and approaches the freezing point (32°F or 0°C), some considerations should be considered before going out with a pet.
