Shih Tzus are brachycephalic dogs, meaning they have short snouts and flat faces, which makes them more prone to overheating and breathing difficulties in hot weather. Unlike humans, dogs cannot sweat efficiently, so they rely on panting and heat dissipation through their paws to regulate body temperature.
During summer, Shih Tzus need extra care and protection to stay cool, comfortable, and safe from heatstroke. In this guide, you’ll learn how heat affects Shih Tzus, signs of overheating, and essential tips to keep your furry friend cool during hot days.
Why Are Shih Tzus Sensitive to Heat?
Shih Tzus struggle more in hot weather compared to some other breeds due to their physical characteristics and thick coat.
1. Short Snout (Brachycephalic Breeds Struggle to Breathe in Heat)
- Shih Tzus have narrow airways, making it harder for them to cool down by panting.
- Hot and humid air worsens breathing problems, increasing the risk of heatstroke.
2. Thick Double Coat (Heat Retention)
- Their long, dense fur can trap heat, making them overheat faster than short-haired breeds.
- Dark-colored Shih Tzus absorb more heat from sunlight.
3. Small Size (High Risk of Dehydration)
- Shih Tzus have small bodies, which means they lose water faster and can become dehydrated quickly.
- Puppies and senior dogs are especially vulnerable.
Because of these factors, Shih Tzus need proper cooling strategies and hydration to stay safe in the summer.
Signs of Overheating in a Shih Tzu
🚨 Watch for these warning signs of heat exhaustion and heatstroke:
- Excessive panting and drooling
- Red or pale gums
- Lethargy and weakness
- Difficulty breathing
- Increased heart rate
- Vomiting or diarrhea
- Collapse or seizures
🔥 If your Shih Tzu shows signs of heatstroke, act quickly! Move them to a cool place, offer fresh water, and apply cool (not icy) water to their paws and belly. Call your vet immediately!
How to Keep Your Shih Tzu Cool in Summer
1. Provide Plenty of Fresh Water
💧 Always keep clean, cool water available. Shih Tzus can become dehydrated quickly, especially in the heat.
- Add ice cubes to their water bowl.
- Use a pet water fountain to encourage drinking.
- Carry a portable water bottle when going outside.
2. Avoid Walks During the Hottest Hours
☀️ Walk your Shih Tzu during early mornings or late evenings when temperatures are cooler.
- Avoid asphalt and hot pavement—if it’s too hot for your hand, it’s too hot for your dog’s paws!
- Walk on grass or shaded areas to protect their paws from burns.
3. Keep Them Indoors in Extreme Heat
🏡 On very hot days, it’s safest to keep your Shih Tzu inside with fans or air conditioning.
- Create a cool resting area with a fan or an air-conditioned room.
- Provide a cooling mat or a damp towel for them to lie on.
- If using a fan, place it near their bed but not directly blowing on them.
4. Trim, But Don’t Shave, Their Fur
✂️ Many owners believe that shaving their Shih Tzu helps in the summer, but this can actually make them hotter!
- Trim their coat short, but never shave down to the skin, as their fur protects against sunburn and heat.
- Brush daily to remove loose fur and prevent overheating.
- If your dog has long fur, tie it up in a topknot to keep their face cool.
5. Provide Shade When Outdoors
🏖️ If your Shih Tzu spends time outside, make sure they have a shady spot to rest.
- Use an umbrella, dog tent, or shaded patio.
- If at the beach or park, bring a cooling mat or wet towel for them to lie on.
6. Give Cooling Treats
🍉 Offer hydrating treats to help regulate their body temperature.
- Frozen watermelon or cucumber pieces
- Dog-friendly ice cream (no sugar or dairy)
- Frozen yogurt mixed with peanut butter (xylitol-free)
7. Use a Cooling Vest or Bandana
🧊 Cooling vests or wet bandanas help lower body temperature by evaporating heat.
- Wet a dog cooling bandana and wrap it around their neck.
- Soak a towel in cool water and drape it over their back.
8. Never Leave a Shih Tzu in a Hot Car
🚗 Even a few minutes inside a hot car can be deadly.
- The temperature inside a car can rise quickly, even with the windows slightly open.
- If you need to go somewhere, leave your Shih Tzu at home in a cool environment.
9. Watch for Breathing Problems
🐶 If your Shih Tzu has difficulty breathing, use a humidifier indoors to help with airflow.
- Monitor their breathing closely on hot days.
- If they show labored breathing, consult a vet immediately.
How to Exercise a Shih Tzu Safely in Hot Weather
Shih Tzus still need exercise, but during summer, modify their activities:
🏠 Indoor play → Use interactive toys or gentle games inside a cool room.
💦 Water fun → Let them play in a shallow kiddie pool or sprinkler (never force them into water).
🐾 Shorter walks → Keep walks brief and in the shade.
What to Do If Your Shih Tzu Gets Too Hot
🚑 If your Shih Tzu shows signs of overheating, act fast:
1️⃣ Move them to a cool, shaded area immediately.
2️⃣ Give them small amounts of cool water (not ice-cold).
3️⃣ Wet a towel with cool water and place it on their paws, belly, and ears.
4️⃣ Turn on a fan or air conditioning to help them cool down.
5️⃣ Call your vet if symptoms persist!
Final Thoughts
Shih Tzus are extra sensitive to heat, but with proper care, you can keep them safe and comfortable during summer. Providing plenty of fresh water, avoiding extreme heat, and using cooling techniques will ensure your furry friend stays happy and healthy all season long.
