How Dogs Regulate Their Body Temperature and How It Differs From Humans

Dogs have a normal body temperature range of 38°C to 39°C, which is slightly higher than humans, who have a standard range of 36.5°C to 37.5°C. Dogs also have a different way of regulating their body temperature than humans. 

While humans sweat through their skin to cool down, dogs only have sweat glands on their paw pads and nose, which are not very practical for cooling. Instead, dogs use panting to evaporate heat from their tongue and mouth. Panting also helps dogs circulate cool air through their lungs and blood vessels.

However, panting has limitations, especially in hot and humid conditions, where the air is saturated with moisture, and the evaporation rate is low. In such situations, dogs can overheat quickly and suffer from heatstroke, a life-threatening condition when the body temperature exceeds 41°C. Heatstroke can cause organ damage, seizures, coma, and death if not treated promptly.

On the other hand, dogs can also lose body heat rapidly in cold weather, especially if they are wet, windy, or have a thin coat. When the body temperature drops below 37°C, dogs can develop hypothermia, which is a condition that occurs when the body cannot produce enough heat to maintain normal functions. Hypothermia can cause shivering, lethargy, confusion, slow breathing, low blood pressure, and cardiac arrest if not treated promptly.

It’s essential to know what temperature is too cold for dogs in cold weather, as they are susceptible to hypothermia.

What Temperatures Are Too Hot for Dogs?

The temperature at which it is too hot for a dog to be outside depends on several factors, including the dog's breed, age, health, fitness level, and humidity level.
Generally, avoiding walking your dog in temperatures above 80 degrees Fahrenheit is best.

Dogs can’t sweat like humans and rely on panting to cool down. However, panting is not very effective when the air is hot and humid, as it reduces moisture evaporation from the tongue and mouth. This can lead to dehydration, sunburn, and heatstroke.

Heatstroke is life-threatening when the body temperature rises above 104 degrees Fahrenheit. It can cause organ failure, brain damage, seizures, coma, and death. Heatstroke can happen in minutes, especially if the dog is exercising or in direct sunlight.

The temperature that is too hot for dogs varies depending on their breed, size, coat type, and activity level. However, as a general rule of thumb, anything over 100 degrees Fahrenheit can be dangerous for most dogs. Some breeds that are more prone to heatstroke include brachycephalic breeds (such as pugs, bulldogs, and boxers), thick-coated breeds (such as huskies, malamutes, and chow chows), and overweight or elderly dogs.

Some signs of overheating in dogs include:

  • Excessive panting
  • Drooling
  • Lethargy
  • Vomiting
  • Diarrhoea
  • Increased thirst
  • Bright red gums and tongue

If you notice any of these signs in your dog, you should act quickly to lower their body temperature. Here are some steps you can take:

  • Move your dog to a shaded or air-conditioned area
  • Offer them cool (not cold) water to drink
  • Apply cool (not cold) wet towels or a fan to their head, neck, chest, and groin.
  • Monitor their temperature with a rectal thermometer
  • Contact your veterinarian as soon as possible

To prevent overheating in dogs, you should follow these tips:

  • Avoid leaving your dog in a parked car, even with the windows cracked open
  • Provide plenty of shade and water when your dog is outdoors
  • Avoid walking or exercising your dog during the hottest hours of the day
  • Use ice cubes, cooling mats, fans, or air conditioning to keep your dog cool indoors
  • Avoid shaving your dog’s coat in summer, as it can increase their risk of sunburn and heatstroke.

What Temperatures Are Too Cold for Dogs?

The temperature at which it is too cold for a dog to be outside depends on several factors, including the dog's breed, age, size, and health, as well as the windchill.
Generally, it is best to avoid letting your dog outside in temperatures below 45 degrees Fahrenheit.

Dogs have fur coats that offer some protection from the cold, but they can still get hypothermia or frostbite if exposed to extreme cold for too long. Hypothermia is a condition that occurs when the body temperature drops below 95 degrees Fahrenheit.

It can cause reduced blood circulation, shivering, muscle stiffness, and tissue damage. Frostbite is a condition that occurs when the skin and other tissues freeze due to exposure to cold. It can affect dogs’ ears, tails, paws, and noses.

The temperature that is too cold for dogs varies depending on their breed, size, coat type, and health condition. However, as a general rule of thumb, anything below 40 degrees Fahrenheit can be uncomfortable for most dogs. 

If your dog needs to be outside for short periods in freezing weather, a homemade dog diaper with an absorbent pad and insulation can help protect sensitive areas like the belly and groin.

Some breeds that are more tolerant to cold include northern breeds (such as huskies, malamutes, and Samoyeds), thick-coated breeds (such as Newfoundlanders, Bernese mountain dogs, and great pyrenees), and small or toy breeds (such as chihuahuas, yorkies, and Pomeranians).

Some signs of hypothermia in dogs include:

  • Slow breathing
  • Low heart rate
  • Pale gums and skin
  • Weakness
  • Confusion
  • Unconsciousness

If you notice any of these signs in your dog, you should act quickly to raise their body temperature. Here are some steps you can take:

  • Move your dog to a warm or heated area
  • Wrap them in warm (not hot) blankets or a heating pad
  • Offer them warm (not hot) water or broth to drink
  • Monitor their temperature with a rectal thermometer
  • Contact your veterinarian as soon as possible

To prevent hypothermia and frostbite in dogs, you should follow these tips:

  • Provide adequate shelter and bedding for your dog when they are outdoors.
  • Limit the time your dog spends outside in cold weather
  • Dress your dog in sweaters, coats, booties, or other accessories that can keep them warm
  • Check your dog’s ears, tail, paws, and nose for signs of frostbite after they come inside
  • Avoid letting your dog walk on ice, snow, or salted roads, as they can cause injuries or irritation to their paws

Factors That Affect Your Dog’s Heat and Cold Tolerance

Some dog breeds are more heat-tolerant or cold-tolerant than others. For example, species with thick coats, such as Huskies and Malamutes, are better able to withstand cold weather than breeds with thin coats, such as Greyhounds and Italian Greyhounds.
If you see signs of heatstroke or hypothermia in your dog, such as excessive panting, bright red gums, or shivering, take them to the vet immediately. These conditions can be fatal if not treated promptly.

Different dogs have different levels of tolerance to heat and cold, depending on various factors such as:

  • Breed: Some breeds are more suited for hot or cold climates than others. For example, breeds with thick coats, like Huskies or Malamutes, are more comfortable in cold weather than breeds with short coats, like Chihuahuas or Greyhounds. Similarly, breeds with flat faces, like Pugs or Bulldogs, are more prone to overheating than breeds with long noses, like Collies or Labradors.
  • Size: Generally speaking, smaller dogs have a larger surface area to volume ratio than larger dogs, which means they lose heat faster than larger dogs. Smaller dogs also have less body fat and muscle mass to insulate them from the cold. Therefore, smaller dogs may need more protection from the cold than larger dogs.
  • Age: Younger and older dogs can less regulate their body temperature than adult dogs. Puppies and senior dogs also have weaker immune systems and may be more susceptible to infections or diseases caused by extreme temperatures.
  • Health: Dogs with certain health conditions or medications may have impaired thermoregulation or increased sensitivity to heat or cold. For example, dogs with heart disease, respiratory problems, diabetes, obesity, or thyroid disorders may have trouble coping with high or low temperatures. Pregnant or nursing dogs may also need extra care and attention in extreme weather conditions.

Conclusion

As responsible pet owners, we must be attuned to our dogs’ needs, and understanding their temperature tolerance is a fundamental aspect of that commitment. Whether it’s providing shade and hydration on a scorching summer day or cozy blankets and indoor warmth during the winter chill, we hold power to create a comfortable and safe environment for our beloved companions. 

By recognizing the signs of discomfort and knowing when to take action, we can ensure that our furry friends lead healthy, happy, and thriving lives year-round. So, let’s continue to be vigilant, compassionate, and well-informed caregivers because some knowledge about temperature can go a long way in keeping our dogs content and thriving every season.
