Chihuahuas are expressive and crammed with personality compared to other dog breeds. Habitually, you will find Chihuahuas playful burrowing under sheets and licking everything that amuses them. They also possess confident, intelligent, peaceful, and bold traits that make them fit for keeping indoors. But the question is, “can Chihuahuas live outside in the cold?”
The answer is NO! It doesn’t count on whether your Chi has a bushy coat, longhaired, or short-haired. All Chihuahua are brachycephalic, which makes them more sensitive to dropping temperatures. To keep warm in the house, Chihuahuas will burrow under towels and blankets.
Always be careful next time you jump on your bed or sitting on your couch not to hurt your Chihuahua. Here are various reasons why the breed cannot live outside in the cold.
Physically Fragile
Chihuahuas are fragile, requiring more attention and monitoring, especially in cold or wet weather. During cold weather, their bodies lose heat quickly, causing them to tremble or shiver if left outside in the cold. Their short or long coats offer no protection to freezing, making the breed an indoor dog. They also develop cold flu and breathing complications due to elongated soft palate.

Sometimes the temperatures are too low in the house, but Chihuahuas are expressive by developing common symptoms. If you observe some of the following behaviors on a cold day, take action in keeping your Chi warmer.
- Trembling and shivering
- Tuck under towels or blankets. Some will make nests with clothes, sheets, or towels
- Lift their paws due to snow or wet ground
- Whining or barking
- Refusing to step outside
Leaving your Chihuahua in the cold can turn into a deadly condition known as hypothermia or frostbite. They are conditions that limit blood circulation, stiff muscles, slowed heartbeat, or to some extent, kidney failure. All these conditions could mean a death sentence to your pet.
4 Degrees Celsius (40 Degrees Fahrenheit)
Wondering how cold is too cold for your Chihuahuas? The lowest temperature Chihuahuas can withstand is an average of 4 degrees Celsius (40 degrees Fahrenheit). Cold winters can lower temperatures when combined with a rainy day. That increases the risk of suffering from cold for your young puppy or older Chihuahuas.
At some point, when it is too cold for a pet walk, Chihuahuas will lift their legs off the ground. It gives you a sign that the land is cold for its paws. Therefore, drying off their paws and keeping them warm will save them from deteriorating health conditions.
When Chihuahuas are exposed to lower than 4 degrees Celsius, maintaining or restoring their normal body temperatures is compromised. Chihuahua breeders will need to make special attention or clothing to keep them warm.

Body Sizes
Chihuahuas come in various sizes. The Teacups are the tiniest of all Chihuahuas. They accommodate more significant risks on health matters. However, leaving your Chihuahua outside in the cold can lead to difficulty in regulating their blood sugars.
You might have left your pet outside healthy and playful before heading to bed. But on waking up the following day, you find them inexplicably dead at your doorstep. The leading cause of such deaths is hypoglycemic shock. It is a condition that makes their internal organs cease functioning mainly because of cold temperatures or lack of eating for long.
Tips for Keeping Chihuahuas’ Warm Outside
