French Bulldog Temperature Tolerance Ultimate Guide 

Extreme temperatures are no friend to French bulldogs. Because of their muzzled flat face they have problems regulating their temperature.

In Summer, they are prone to overheating because of their compact structures along with being brachycephalic. On the contrary, in winter, they might face difficulty breathing due to the narrow nostrils that don’t allow sufficient airflow. As a result, they lose the heat at the same speed as they produced it. 

Seems like a tricky thing to handle. Right? 

But this tiny thing shouldn’t stop you from becoming a proud Frenchie parent.

You can take some precautions and maintain your furry Frenchie companions’ temperature efficiently. 

To help, we have created this detailed French bulldog temperature tolerance guide so that you know everything that will help you keep your Frenchie at ease in extreme weather.

Is the French Bulldog an Outside Dog?

The French Bulldog, or “Frenchie,” is a small, adorable breed of dog that has gained immense popularity over the past decade. 

Known for their playful, friendly temperament and distinctive, “bat-like” ears, Frenchies have become a popular choice for families and city dwellers alike. Many prospective Frenchie owners ask whether this breed can be kept as an outside dog.

First, it’s worth noting that French Bulldogs are not typically considered outdoor dogs. Their short, flat nose and small airways make them a brachycephalic breed. 

This can make them more prone to overheating in hot weather, leading to heat exhaustion and other health problems. Additionally, Frenchies are a social breed that loves human interaction, and they may become bored or anxious if left outside for extended periods.

That being said, there are some situations in which a French Bulldog can live outdoors comfortably. 

For example, if you live in a mild climate and can provide your Frenchie with a well-insulated doghouse and plenty of shade and water, they may be able to spend some time outside during the day. Additionally, if you have a large, securely fenced yard that your Frenchie can run and play in, this may be an excellent way to give them some exercise and fresh air while keeping them close to home.

However, it’s important to remember that French Bulldogs are not natural outdoor dogs; they will require plenty of attention and care if you keep them outside. 

You will need to ensure they have access to clean water at all times, and you may need to invest in additional tools, like a heated dog bed or cooling pad, to help regulate their temperature in extreme weather conditions. You must also provide your Frenchie with plenty of socialization and exercise, even if they are primarily outdoor pets.

While French Bulldogs are not typically considered outdoor dogs, they can thrive in the right environment with proper care and attention. 

If you are considering keeping a Frenchie as an outdoor pet, take the time to research their needs and talk to a veterinarian or experienced Frenchie owner to get more information. Your French Bulldog can be a happy and healthy outdoor companion with the proper setup and care.

French Bulldog Heat Tolerance: The Ideal Temperature Range for a French Bulldog

If you want to get an idea of the ideal temperature range for a French bulldog, it has to be somewhere in the range of 15°C (59°F) and  21°C (70°F). 

And, you have to be really careful about the temperature going up or the weather turning chilly because anything up to 26°C (80°F) and lower than 7°C (45°F) can be a potential danger to your beloved.

Even your French bulldog will start showing discomfort at 10°C (50°F). 

The temperature thresholds can differ with their age. 

French Bulldog Signs of Overheating

French Bulldogs, like all dogs, are susceptible to overheating, especially during hot weather or when exercising vigorously. Here are some signs to look out for if you suspect your French Bulldog may be overheating:

  1. Excessive Panting: Panting is normal for dogs, but excessive panting can be a sign that your French Bulldog is overheating.
  2. Drooling: Excessive drooling is another sign that your French Bulldog may be overheating. This is because dogs sweat through their tongues, and they may drool more than usual when overheating.
  3. Lethargy: Overheating can make your French Bulldog feel tired and sluggish. If your dog seems less energetic than usual or is unwilling to play or exercise, it may be overheated.
  4. Red or pale gums: Check your French Bulldog’s gums. If they are bright red or pale, this could be a sign of overheating.
  5. Vomiting or diarrhea: Overheating can cause your French Bulldog to vomit or have diarrhea.

If you suspect that your French Bulldog is overheating, take immediate action to cool them down. 

Move them to a cooler area, offer them water, and use cool (not cold) water to wet their fur or use a damp towel to help lower their body temperature. 

If their symptoms persist, contact your veterinarian for further advice. Avoiding hot weather and providing plenty of water and shade when exercising or spending time outdoors with your French Bulldog is essential to prevent overheating.

Tips to prevent overheating 

In Summer, your Frenchie can easily get overheated. Here are some tips to keep them cool and prevent overheating: 

  1. Arrange whatever you can to keep your Frenchie cool. Do you have a fan? Well, that can help. Can you pamper him with an Air Conditioned space? That will be great! Just do whatever you can provide your dog with whatever they not need in their surroundings to keep them within the recommended temperatures. 
  2. Keeping your dog hydrated will also be a great way to keep their body temperature in control. You may also add some ice cubes to their water or even cold treats (ie. frozen pumpkin ice cubes).
  3. Buy a Cooling vest for your adorable companion. This will be one of the best investments you’ll ever make for your Frenchie. A cooling vest is handy whether you want to stay inside with your dog or go outside with your Frenchie. 
  4. Play and exercise your French bulldog in a cool environment.

French Bulldog Cold Tolerance

Just like French bulldogs can’t keep up the summer heat, they also have a hard time in cold temperatures. 

We have already mentioned an ideal range of temperatures that a French bulldog can tolerate. Still, if we specifically talk about winters, you should take action when the temperature drops below 7°C or 45°F. 

You can take the following steps to make your dog warm right away. 

Step 1: Bring your French Bulldog inside. 

Step 2: Dress your Frenchie in warmer clothes. 

Before we talk about some signs that your French Bulldog is feeling cold or give you some tips to keep them warm, let’s tell you about some top reasons you shouldn’t expose your French Bulldog to colder temperatures.

3 Top Reasons You Must Not Expose Your Frenchie to Cold Temperatures 

Below we discuss the top 3 reasons you must keep your French bulldog from cold temperatures.

  1. Your French bulldog has a relatively short coat which is not an excellent barrier to protect them from bone-chilling winds. 
  2. They have little to no adaptability to cold weather. 
  3. Frenchies are prone to respiratory problems that can get severe due to cold weather. 

Now let’s discuss them one by one in more detail.

  1. Short Coat: 

One of the main reasons French Bulldogs are sensitive to cold weather is their short, smooth coat. This type of fur provides very little insulation, which means your dog cannot retain body heat as effectively as other breeds with thicker fur.  This makes them more vulnerable to the elements, and they may feel cold and uncomfortable even in mildly cold weather.

Exposure to cold temperatures can cause your Frenchie to experience shivering and discomfort, which can eventually lead to hypothermia. Hypothermia is a serious medical condition when a dog’s body temperature drops too low. Left untreated can lead to organ failure, coma, and even death. 

This is particularly dangerous for French Bulldogs as they are a brachycephalic breed and can have breathing difficulties. As such, keeping your Frenchie warm and cozy during the colder months is crucial to prevent them from getting sick or uncomfortable.

Consider investing in a good quality coat or sweater to keep your French Bulldog warm and cozy. These can help provide additional insulation and keep your Frenchie’s body heat. 

You should also limit your dog’s time outdoors in cold weather and ensure they can access a warm and comfortable indoor space. Remember that Frenchies are not as adaptable to extreme temperatures as other breeds, so you must take extra precautions to protect them from the cold.

  1. Lack of Adaptability:

Another critical reason why French Bulldogs are sensitive to cold weather is their lack of adaptability. This breed is not well-suited to extreme temperatures and struggles to regulate its body temperature. They are more comfortable in moderate temperatures, so exposure to extreme cold can put them at risk of other health issues. This is especially true for puppies, senior dogs, and those with underlying health conditions.

This lack of adaptability also means that French Bulldogs should be kept from being outdoors for extended periods during the winter. 

If they must go outside, it’s essential to keep their outdoor time to a minimum and provide them with a warm and dry shelter. It is also essential to monitor their behavior closely and bring them indoors if they show discomfort or distress.

Owners must take extra care to protect their furry friends during colder months to prevent them from getting sick or uncomfortable. You can keep your Frenchie healthy and happy throughout the winter by providing a warm and cozy indoor environment and minimizing their outdoor exposure.

  1. Respiratory Problems: 

French Bulldogs are known to have respiratory problems due to their short snouts and flat faces. This can make it difficult for them to breathe properly, particularly in cold weather. When your French Bulldog is exposed to cold temperatures, their airways can become constricted, making it even more difficult for them to breathe. This can lead to serious health problems and even put their life at risk. 

It’s essential to avoid exposing your Frenchie to cold temperatures to protect their respiratory health.

As a responsible pet owner, taking the necessary steps to protect your French Bulldog from the cold is essential. You can ensure they stay healthy and happy year-round by providing a warm and comfortable environment.

Signs Your French Bulldog is Too Cold

Your Frenchie furball can get too cold in the winter if not handled properly. Hence, you must keep your Frenchie warm and keep your eyes glued to the temperature scale on the thermometer so that you can take immediate action. 

The short coats of the Frenchies are the main culprit of making your dog feel too cold. Here are some signs that will notify you that your small furry Frenchie cannot keep themselves warm. (You may call it a quick “cool” test.)

  1. Shivering: Shivering clearly indicates that your French Bulldog is too cold. Just like humans, dogs shiver to generate heat and warm up their bodies.
  2. Slow movements: If your French Bulldog seems to be moving more slowly than usual, it could be a sign that they are too cold. When dogs are cold, their body movements can become slower and more sluggish.
  3. Whining or whimpering: Dogs may vocalize when uncomfortable or distressed. If your French Bulldog is whining or whimpering more often, it could be a sign that they are too cold. However, Frenchies suffer of separation anxiety so they could also be whimpering for you attention.
  4. Curling up: Dogs often curl up in a ball when they are feeling cold, which helps them conserve body heat. An overly cold French Bulldog might curl up more than usual.
  5. Cold ears or paws: Check your French Bulldog’s ears and paws. If they feel cold to the touch, this clearly indicates that your dog is too cold.

If you notice any of these signs, it’s essential to warm up your French Bulldog. You can offer them a warm blanket or sweater, turn up the heat in your home, or snuggle up with them to share your body heat. Avoid leaving your French Bulldog outside for extended periods in cold weather, and ensure they have access to warm shelter and plenty of water.

By being mindful of your French Bulldog’s needs and taking proactive steps to keep them warm, you can help ensure they stay happy and healthy during the colder months.

Can French Bulldogs Go in Snow?

French Bulldogs can go in the snow, but taking precautions is essential to ensure their safety and comfort in colder temperatures.

Like all dogs, French Bulldogs need exercise and outdoor time to maintain their physical and mental health. However, they are a brachycephalic breed, which means they have a shorter snout and can have trouble regulating their body temperature in extreme weather conditions. This makes it especially important to monitor their behavior outside in the snow.

To ensure your French Bulldog is comfortable in the snow, consider providing them with a warm coat or sweater to keep them warm and dry. Especially for dogs with thin fur or short hair, this can be helpful. You may also want to protect their paws from the cold, which can cause frostbite or other injuries. Consider using booties or paw wax to keep their paws safe and comfortable.

When taking your French Bulldog out in the snow, be mindful of its behavior and any signs of discomfort. If they start shivering or seem hesitant to move, it’s time to head back indoors and warm up. Keep your walks shorter and take frequent breaks to allow your dog to rest and warm up if needed.

French Bulldogs can enjoy the snow, but you must be mindful of their safety and comfort in colder temperatures. With some preparation and attention, you and your French Bulldog can play in the snow together!

Tips to Keep Your Frenchie Warm

When winter is around the corner, you must take steps to keep your Frenchie warm. Here are some actionable tips to get you started: 

  1. Help your Frenchie adapt and prepare for the forthcoming winters by keeping your thermostat levels above 12°C or 32°F.
  2. Next is the time to move your Frenchie’s bed. Shift it to a warm place, away from chilly areas. 
  3. Buy some cute sweaters and jackets for your French Bulldog. Adding some Frenchie booties and socks to the wardrobe also would be of great help. You can also DIY them using your old sweaters or jackets. Ensure the sweaters or any other wearable items fit your dog correctly. Too loose won’t give a snug feeling to your dog, and too tight might cause discomfort to the dog.   
  4. Don’t even think of getting your Frenchie wet in the winter! Whenever grooming and cleaning try to use less water than normal. Consider dry bathing them.
  5. Winters don’t mean that your French bulldog must remain in bed snuggling in the warm blanket all day. You must exercise them and play with them to maintain the activity levels.
