How Cold is Too Cold for Shih Tzus: 

Signs of Hypothermia & Frostbite

Overview

Shih Tzus, with their small size, brachycephalic profile, and coats of hair (not fur), are particularly vulnerable to cold weather. Unlike breeds with double coats of fur designed to insulate against the elements, Shih Tzus often need some help staying warm and safe during cold winter months. When temperatures drop, the risk of hypothermia or frostbite increases.  

This article is your complete guide to understanding how cold is too cold for Shih Tzus, the early warning signs of hypothermia and frostbite, and cold weather safety tips for both puppies and adult dogs. From temperature limits to practical tips for outdoor adventures, we’ll help you ensure your Shih Tzu remains cozy, healthy, and happy through the colder months.

Why Are Shih Tzus Sensitive to Cold?

Though it varies from dog to dog, some Shih Tzus are particularly vulnerable to cold weather in comparison to many other breeds due to several factors:

• Small Body Size and Low Body Fat: Shih Tzus can lose body heat quickly because of their petite frames and minimal fat reserves, which are essential for retaining warmth. For young or undersized Shih Tzu, this is very relevant.
• Hair, Not Fur: Unlike breeds with double coats of fur designed for insulation, Shih Tzus have a double coat of hair. While beautiful, it offers far less protection against cold temperatures.
• Brachycephalic Anatomy: Their short noses and flat faces make it harder for Shih Tzus to regulate their body temperature, increasing their sensitivity to both heat and cold.
• Primarily Indoor Living: Shih Tzus are indoor dogs and are less acclimated to chilly outdoor conditions than some other breeds.

What Temperatures Are Too Cold for Shih Tzus?

Let’s take a look at the exact temperatures that most Shih Tzu dogs may find chilly or cold and when it’s too cold to go outside. 

Temperature Guidelines for Shih Tzus:

• 50°F (10°C): Shih Tzus may start to feel chilly at this temperature, especially during extended outdoor activities. A well-fitting dog coat or sweater can help keep them comfortable.
• 40°F (4°C): At this point, discomfort becomes more noticeable. Most Shih Tzu dogs will tolerate this temperature better if they wear a warm vest. Young puppies under 5 months old should have very limited time outdoors in this temperature range, especially if there’s wind or dampness, which can make it feel colder.
• 32°F (0°C): Freezing temperatures bring a significant risk of hypothermia. Outdoor exposure should be limited to about 15 minutes, and ensure your Shih Tzu is dressed warmly with a lined coat and possibly dog booties to protect their paws.
• 20°F (-6°C): This is a dangerous temperature for most Shih Tzu dogs. Avoid outdoor exposure unless absolutely necessary, as frostbite and hypothermia can occur quickly.

Factors That Affect Safety:

• Wind Chill: Even if the thermometer reads above freezing, wind chill can make it feel much colder, significantly increasing the risk of cold-related issues. Always account for the "feels-like" temperature when planning outings.
• Dampness and Wet Conditions: Wet hair and paws from snow, rain, or ice can lower your dog’s body temperature rapidly. Dry your Shih Tzu thoroughly after any time outside, even if it’s brief.
• Activity Level: Short bursts of play can help keep your dog warm, but prolonged exposure, especially if they’re inactive, increases the risk of cold-related health issues.

Signs of Hypothermia in Shih Tzus & Actions to Take

Hypothermia is an often-dangerous condition that occurs when one's body temperature drops below its normal range, usually due to prolonged exposure to cold conditions. Taking action early is important for preventing serious health complications. Here’s what to watch for at each stage:

Mild Hypothermia

Signs:

• Shivering
• Cold ears or paws
• Restlessness or reluctance to move

What to Do:

• Bring your Shih Tzu indoors immediately: Move them to a warm, draft-free area in the home.
• Provide extra warmth: Wrap your dog in a cozy blanket, focusing on warming their core. If you have a pet-safe heating pad, use it on a low setting.
• Offer warm (not hot) liquids: If your Shih Tzu is shivering or seems restless, warm water or low-sodium chicken broth can help increase their body temperature.
• Monitor closely: Watch for worsening symptoms, such as lethargy or shallow breathing, which indicate moderate hypothermia (see next).

Moderate Hypothermia

If exposure to the cold continues, a Shih Tzu’s body will struggle to regulate its temperature.

Signs escalate to:

• Lethargy
• Shallow breathing
• Pale gums

What to Do:

• Seek immediate veterinary advice: Call your vet and describe the symptoms. They can provide guidance on first aid and whether emergency care is necessary.
• Continue warming gradually: Use body heat or a warm blanket to stabilize your dog’s temperature, ensuring their chest and abdomen are insulated.
• Avoid sudden, extreme temperature changes: Never use hot water bottles or heated blankets directly on your dog’s skin, as their reduced blood flow makes them more prone to burns.
• Limit movement: Keep your Shih Tzu calm and still, as exertion can cause further energy loss.

Severe Hypothermia

Severe hypothermia should be considered life-threatening and this calls for immediate veterinary care. 

Signs:

• Stiffness: The body begins to shut down, leading to muscle rigidity.
• Loss of consciousness: This is a critical emergency; a dog needs immediate warmth and medical attention.
• Slow heartbeat

What to Do: 

• Get to a vet immediately: Severe hypothermia is a medical emergency. Bring your Shih Tzu to the nearest veterinary clinic as quickly as possible.
• Warm carefully en route: Use your body heat by holding your Shih Tzu close or wrapping them in a thermal emergency blanket. Focus on warming their chest and abdomen.
• Do not attempt feeding or drinking: A severely hypothermic dog’s ability to swallow may be impaired, increasing the risk of choking.
• Follow professional advice: Once at the clinic, the vet may administer warmed IV fluids, oxygen, or other treatments to stabilize your Shih Tzu.
  

Additional Considerations

Keep in mind that Shih Tzus, due to their small size and coats of hair, are particularly vulnerable to hypothermia. They may show signs more quickly than larger or breeds with fur. Always monitor your dog’s behavior when temperatures drop, and be vigilant for early symptoms.



By understanding the signs of hypothermia, you can intervene before it becomes a serious risk, ensuring your Shih Tzu stays safe, warm, and healthy through the winter months.

Signs of Frostbite in Shih Tzus & Actions to Take

Frostbite occurs when the body directs blood flow away from extremities to preserve core temperature, causing the tissue in exposed areas to freeze. Due to their small size, coat of hair, and delicate paws, Shih Tzus are susceptible to frostbite, particularly on their ears, tail, and paw pads. Recognizing the signs early is crucial to prevent permanent damage.

Signs of Mild Frostbite:

Initially, frostbitten areas may appear pale or grayish-blue due to reduced blood flow. The skin may feel cold and hard to the touch, and a Shih Tzu might lick or chew at the affected area in discomfort.

Signs of Moderate Frostbite:

As frostbite progresses, the affected tissue may swell and become red or purple as blood flow begins to return. A Shih Tzu may yelp or pull away if you touch the area, as frostbite is painful. Vet care is crucial at this stage.

Signs of Severe Frostbite:

In severe cases, the tissue may turn dark or black, indicating necrosis (tissue death). At this stage, immediate veterinary intervention is required to prevent further complications or loss of the affected area.

What to Do if You Suspect Frostbite:

• Warm the affected area slowly using a warm (not hot) towel or pet-safe heating pad. Avoid applying direct heat, such as a hairdryer, as it can damage sensitive tissue.
• Keep your Shih Tzu calm and warm by wrapping them in a blanket and moving them indoors immediately.
• Do not rub the frostbitten area in an attempt to warm it, as this can cause further tissue damage.
• Contact your veterinarian as soon as possible, especially if the skin shows signs of moderate to severe frostbite or if your Shih Tzu seems lethargic or unresponsive.

Preventing Hypothermia & Frostbite in Shih Tzus

With the right precautions, you can keep your little guy or gal safe, warm, and comfortable even during freezing weather. Here’s what every Shih Tzu pet-parent should know to protect their dog from the dangers of cold temperatures.

#1 Dress Your Shih Tzu for Winter

Proper winter gear is essential to help a Shih Tzu retain body heat and stay protected in cold or icy conditions:

• Insulated Coats: A well-fitted, insulated dog coat that covers their chest, back, and sides is vital. Look for options that are waterproof to protect against snow or rain. Avoid coats that are too loose, as they can let cold air in. One that we like a lot is the AimyDog Winter Coat, which has a built-in harness with a D-ring, is waterproof and windproof, has a thick polar fleece lining, and provides great coverage for the wide profile bodies of Shih Tzu dogs. 
• Paw Protection: Shih Tzu paws are vulnerable to frostbite and irritation from icy surfaces or de-icing chemicals. Use a quality paw wax like Musher's Secret to create a protective barrier against frost, salt and slippery surfaces. Alternatively, non-slip dog boots can shield paws and improve traction on slippery ground, but many dogs do not tolerate wearing them.

#2 Limit Outdoor Exposure According to the Temperature

Extreme cold weather is not only uncomfortable for a Shih Tzu; it can become dangerous, so keep the following in mind:

• Time Limits Based on Temperature: Keep outdoor walks brief when temperatures approach 32°F (0°C). When it dips below 20°F (-6°C), avoid outdoor exposure altogether except for very short potty needs. At these temperatures, frostbite and hypothermia become real risks.
• Monitor Conditions: Wind chill and dampness can make it feel much colder than the actual temperature. Always factor in the "feels-like" temperature when planning outings.

#3 Create a Warm-Up Routine

It can help to take a couple extra steps after outdoor time to ensure your little sweetie warms back up quickly. Let this become part of your Shih Tzu’s normal wintertime routine. 

• Dry Them Thoroughly: Wet hair can cause a Shih Tzu to lose heat rapidly. Use a towel to dry their paws, belly, and coat immediately after outdoor activities.
• Warm Resting Area: Provide a cozy spot with extra warmth, using blankets or line their dog bed with a pet-safe heating pad, like the Toozey Pet Heating Pad, to help your Shih Tzu regulate their body temperature. This is especially important to help remove the chill after being outside and is particually helpful for young pups and dogs 8+ years that may have some arthritis. 

Cold Weather FAQ

Do Shih Tzus like cold weather?

Some Shih Tzu dogs are happy to be outside no matter the temperature and others are full-fledged couch potatoes. This has a lot to do with age, but also is dependent on the Shih Tzu’s unique personality. Many don’t mind chilly days if they are bundled up and doing something fun. With snow, many prefer shoveled paths and will venture out for a while if they are encouraged. 

Can Shih Tzus tolerate snow?

Yes, Shih Tzus can tolerate snow in short or moderate bursts, but they are not naturally built for extended exposure to cold weather. Their small size and coats of hair make them lose heat quicker than their furred counterparts. Always limit their time in the snow, dress them in a warm coat, and monitor for signs of discomfort like shivering or reluctance to move.

How can I tell if my Shih Tzu is cold?

A Shih Tzu may show signs of being cold by shivering, tucking their tail, or seeking warmth by curling up or trying to climb into your lap. Cold ears, paws, or a reluctance to walk outdoors can also indicate discomfort. If you notice these signs, bring your little guy or gal inside and warm them up with a cozy blanket.

Should I walk my Shih Tzu during the winter?

Yes, you can and should walk your Shih Tzu during the winter, but it’s important to take precautions. Do not take extended walks when it’s 40°F (4°C) or below unless they are really bundled up well with an insulated coat and with their paws protected with paw wax or boots. Avoid walking them if temperatures drop below 20°F (-6°C) or if icy conditions make it unsafe.

A Final Thought

Caring for your Shih Tzu during the colder months requires extra attention, but the effort is well worth it to ensure their safety and happiness. As a breed particularly vulnerable to the effects of cold weather, Shih Tzus benefit from thoughtful adjustments to routines and preventive measures like warm clothing, shorter outdoor sessions, and plenty of indoor stimulation. By recognizing the early signs of hypothermia and frostbite, you can act quickly to protect your little companion.
