As a general rule of thumb: at 45°F (7°C) and below, most dogs will dogs will start to become uncomfortable. at 32°F (0°C) and below, small, thin-coated, young, old and sick dogs should not be left outside for long. at 20°F (-7°C) and below, dogs become vulnerable to hypothermia and frostbite.
It's potentially unsafe for little-or-medium-sized dogs with thin coats to be outside, but big dogs with heavier coats are probably OK. When the temperature drops to 20 degrees Fahrenheit and below, all dogs are at a higher risk of hypothermia and frostbite.
Medium dogs (25-50 pounds) can be outside for 30 seconds per degree. Small dogs (15-25 pounds) can only withstand 15 seconds per degree and extra small dogs (less than 15 pounds) 7 seconds per degree.
It's generally safe in temperatures of up to 19°C (68°F) but be careful when the mercury rises above this. Even at temperatures as low as 20°C (70°F) dogs are at risk of heat stroke.
Cold Temperature Guidelines for Dogs
In general, cold temperatures should not become a problem for most dogs until they fall below 45° F, at which point some cold-averse dogs might begin to feel uncomfortable.
Do Dogs Get Cold at Night? It is possible for dogs to get cold at night, even if they're kept indoors. "If you think your dog is getting cold at night, consider giving him a cozy blanket to snuggle up to in bed. Most dogs will not feel cold at night or will seek out a warmer place if they do," says Satchu.
As a general guide, above seven degrees is considered safe for most breeds. If the weather drops to below zero, it is beginning to become unsafe for most dogs. Below minus 12 degrees, while unlikely in Australia, is considered life-threatening.
Beyond that, more specific advice depends on the size of your dog and the density of its natural coat. Rachel says: "Temperatures around -4°C and below are too cold for short-haired dogs, while long-coated dogs can handle slightly lower temperatures, down to -9°C."
Seven degrees Celsius is possibly dangerous for some breeds. When the temperate drops to 4 degrees Celsius and below, it can be life threatening for most dogs. As well as temperature, consider the wind-chill. It is important to think about how cold it really feels.
In general, when the temperature dips below freezing, limit your dog's outdoor activity to 10 to 15 minutes. Watch closely for signs of distress like shivering, lethargy, disorientation, or whining. Just like you, your dog can suffer from hypothermia and frostbite.
Most healthy medium or large dogs can walk for 30-minutes if the temperature is above 20 degrees F. Smaller dogs should limit the walk to 15 or 20 minutes if temps are between 20 to 32 degrees F. If it's below 0 degrees, no dog should be out for a walk.
Cats and dogs should be kept inside during cold weather. It's a common belief that dogs and cats are more resistant than people to cold weather because of their fur, but it's untrue. Like people, cats and dogs are susceptible to frostbite and hypothermia and generally should be kept inside.
During winter, dogs paws are especially vulnerable.
Just like us, dogs are sensitive to cold. Exposure to cold air, rain and snow can cause chapped paws and dry, itchy skin. Then there's things like ice, chemicals and melting salts that can hurt your dog.
If your dog is whining, barking, or howling, start listening. Animals who have been outside in the cold too long may start to whine, bark, or howl. They're trying to tell you that they're freezing-cold and need to go inside and warm up—just like this dog, Charlie.
Although coastal Australia isn't known for especially cold weather, when the winter months arrive there are a number of steps you should take to keep your dog healthy and warm. Of course, some dog breeds handle winter weather better than others, but as the temperature drops, so does your pup's tolerance for the cold.
So, how do you know if it is too hot to walk your dog? Experts agree that it is generally safe to take your canine pal for a walk in temperatures of up to 68F, while anything over 77F is considered very risky.
For medium and large breed dogs, it's best to avoid temperatures colder than -10C, although this varies by breed.
How long should dogs be out in the cold? Large breeds can walk in -6°C for about 30 minutes, while smaller breeds should be limited to walks of fewer than 20 minutes in freezing temperatures. Dogs should never be left outdoors when the weather drops below 10°C.
Normal body temperature for dogs and cats is 101.0 to 102.5°F (38.3 to 39.2°C). Some people and some pets maintain a baseline temperature a little above or below the average, but if your pet's temperature rises above 104°F (40.0°C) or falls below 99°F (37.2°C), take your pet to your veterinarian.
We would advise all dog owners to be mindful about letting your dog sleep outside, and to take in a number of factors before doing so, such as temperature and weather conditions; security of the area; risk of other animals, and more.
Most experts agree: Cats and dogs are better off as indoor pets.
If the tips of your pet's ears are warm, they're probably warm enough all over – the extremities tend to get cold first. Animals which are smaller, leaner, or animals with shorter coats will feel the cold much more acutely.
Even if your dog has a thick, heavy coat, they might still feel chilly in the winter. Pets are just as likely to get frostbite (frozen skin and tissue) and hypothermia (low body temperature) as their owners.
Keep Your Dog Warm – Sleeping on a blanket instead of tile or a hardwood floor can provide your dog a source of warmth and comfort on a cold winter night. This is especially true if you don't sleep in the same room as your dog, or don't allow them on your living room furniture.
