St. Bernard Hot & Cold Weather Tolerance – What Temperatures Can They Handle?

St. Bernards have a rich history as mountain rescue dogs in the Swiss Alps, where they were bred to withstand harsh alpine conditions. Their remarkable adaptability to extreme weather is a result of several key factors:

  • Thick Double Coat: St. Bernards possess a thick double coat consisting of a soft and dense undercoat and a longer, rougher outer coat. This coat acts as natural insulation, providing protection against both cold and heat.
  • Large Body Mass: With their impressive size and build, St. Bernards have a larger body mass, which allows them to retain heat in cold weather while also moderating their body temperature in warmer climates.
  • Built for Snow: Their webbed feet and powerful limbs are adaptations that help them navigate snowy terrain with ease, making them well-suited for colder environments.
  • High Tolerance to Altitude: Being mountain dogs, St. Bernards have a high tolerance for altitude, which means they can handle lower oxygen levels often found in higher elevations.

St. Bernard Hot Weather:

What Temperature is Too Hot for St. Bernards

While St. Bernards can tolerate cold weather well, they are less heat-tolerant due to their thick fur and large size. In hot weather, St. Bernards can be susceptible to heat-related illnesses. Generally, temperatures above 26°C (80°F) can cause discomfort and anything above 32°C (90°F) becomes hazardous for them.

How to Keep Your St. Bernard Cool

To keep your St. Bernard comfortable in hot weather, consider the following measures:

  • Provide Shade: Ensure your St. Bernard has access to shaded areas, especially during peak sunlight hours.
  • Cooling Mats: Use cooling mats or damp towels for your dog to lie on to help lower body temperature.
  • Hydration: Always have fresh water available to prevent dehydration.
  • Avoid Overexertion: Limit physical activity during the hottest parts of the day.
  • Avoid Hot Surfaces: Prevent your dog from walking on hot pavement or surfaces that can burn their paws.

Factors That Impact a St. Bernard’s Heat Tolerance

Several factors can affect a St. Bernard’s ability to handle hot weather:

  • Age and Health: Puppies, seniors and dogs with pre-existing health conditions are more susceptible to heat stress.
  • Coat Thickness: Despite their dense fur, their undercoat plays a role in temperature regulation, but it is inadequate for extreme heat.
  • Fitness Level: Overweight dogs have greater difficulty dissipating heat due to their additional insulation.

Health Risks Associated With Hot Weather

St. Bernards are prone to heat exhaustion and heatstroke in hot weather. Signs of heatstroke include excessive panting, weakness, vomiting and collapse. Immediate action must be taken if heatstroke is suspected.

Signs of Heatstroke in St. Bernards

Watch for signs of heatstroke, such as excessive drooling, rapid pulse, glazed eyes and difficulty breathing. If you suspect heatstroke, move your dog to a cool area, wet them with cool water and seek immediate veterinary attention.

  • Panting: Rapid, excessive panting is a primary indicator.
  • Gums and Tongue: Red or pale gums and a bright red tongue, are concerning.
  • Lethargy: If your St. Bernard appears weak, fatigued, or disoriented, act promptly.

Should You Leave St. Bernards in Hot Cars?

Under no circumstances should St. Bernards be left unattended in hot cars. Even with the windows cracked, the temperature inside a car can escalate rapidly, leading to life-threatening conditions for your pet.

Nutrition & Hydration for Hot Weather

During hot weather, it’s essential to adjust your St. Bernard’s diet to keep them hydrated. Offer fresh water regularly and consider feeding them cooling foods like frozen treats or wet food to help maintain hydration.

  • Hydration: Ensure they have constant access to cool water.
  • Balanced Diet: Maintain a balanced diet to support their overall health and well-being.

St. Bernard Cold Weather:

Do St. Bernards Get Cold?

St. Bernards are well-adapted to handle cold weather, thanks to their thick double coat and large size. They excel in snowy conditions and thrive in colder climates.

How Cold Can a St. Bernard Handle?

St. Bernards can comfortably handle temperatures as low as -10°C (14°F) and even colder with proper care. Their thick fur provides insulation against cold and they often enjoy the colder weather.

How to Keep Your St. Bernard Warm

Even though St. Bernards are well-equipped for cold weather, it’s essential to take precautions during extreme cold:

  • Provide Shelter: Ensure your St. Bernard has access to a warm and insulated shelter when outdoors.
  • Winter Clothing: In severely cold conditions, consider using dog sweaters or coats to provide extra warmth.
  • Limit Outdoor Exposure: Minimize time outdoors during frigid temperatures.
  • Avoid Ice and Snow Buildup: Remove ice and snow from your dog’s paws and coat to prevent discomfort.

Factors That Impact a St. Bernard’s Cold Tolerance

Several factors can influence a St. Bernard’s ability to handle cold weather:

  • Coat Thickness: Dogs with thicker coats can tolerate colder temperatures better.
  • Health: Underlying health conditions can impact cold tolerance.
  • Age: Puppies and senior dogs may have a harder time retaining body heat.

Health Risks Associated With Cold Weather

St. Bernards are susceptible to frostbite and hypothermia in extremely cold weather. Signs of frostbite include discoloration of the skin and cold extremities. Hypothermia may present with shivering, lethargy and muscle stiffness.

  • Hypothermia Symptoms: Watch for shivering, lethargy and muscle stiffness.
  • Frostbite Concerns: Extremely cold conditions can lead to frostbite on their paws, ears and tail.

Nutrition & Hydration for Cold Weather

Adjust your St. Bernard’s diet to maintain optimal body condition during colder months. Make sure they have access to fresh water even in sub-zero temperatures.

Signs of Hypothermia in St. Bernards

Signs of hypothermia include shivering, weakness and confusion. If you suspect hypothermia, move your dog to a warm area, cover them with blankets and seek veterinary attention immediately.

  • Warmth and Care: Gently warm them with blankets and seek veterinary attention.

Can St. Bernards Live Outside?

Whether St. Bernards can live outside depends on the climate and specific conditions. While they can handle colder weather due to their thick coats, they are not well-suited for living in extremely hot environments. If kept outside, provide a well-insulated shelter and access to fresh water at all times.

Moving a St. Bernard From a Hot Climate to a Cool Climate (and Vice-Versa)

Moving a St. Bernard from a hot climate to a cool one or vice-versa requires careful acclimation. Gradually introduce your dog to the new environment, monitor their comfort and provide any necessary adjustments to ensure they adapt successfully.

St. Bernards are remarkable dogs known for their resilience in various weather conditions. Understanding their hot and cold weather tolerance is vital for prospective pet owners. By providing appropriate care, attention and understanding of their unique needs, St. Bernards can thrive and become cherished members of any loving family.
