As responsible pet owners, it’s crucial to understand our furry friends’ limits when it comes to temperature extremes. 

Whether you’re planning a summer adventure or gearing up for a frosty winter, this article will provide you with valuable insights into how dogs cope with varying temperatures and what you can do to keep them safe and comfortable. 

So, let’s embark on this journey to uncover the temperature thresholds that can affect your canine companion’s well-being.


Why Temperature Matters for Dogs

Dogs have a lower tolerance for temperature extremes than humans. This includes understanding what temperature is too cold for dogs to remain comfortable and healthy

Dogs have a normal body temperature range of 99.5 to 102.5 degrees Fahrenheit (37.5 to 39.2 degrees Celsius). 

This is slightly higher than the human range of 97.6 to 99.6 degrees Fahrenheit (36.4 to 37.6 degrees Celsius). However, dogs have a lower tolerance for temperature extremes than humans do. This means that dogs can overheat or get hypothermia more easily than humans.

Overheating or heatstroke is a condition where the dog’s body temperature rises above 105 degrees Fahrenheit (40.5 degrees Celsius) and cannot be cooled effectively. This can cause severe damage to the dog’s organs and can result in death. Some of the causes of overheating in dogs are:

  • Exposure to hot or humid environments, such as a parked car, a sunny yard, or a poorly ventilated room
  • Excessive exercise or physical activity in warm weather
  • Lack of shade, water, or ventilation
  • Breed, age, size, health, and coat factors that affect the dog’s ability to dissipate heat

Hypothermia is a condition where the dog’s body temperature drops below 99 degrees Fahrenheit (37.2 degrees Celsius) and cannot be warmed effectively. This can cause impaired bodily functions and can also result in death. Some of the causes of hypothermia in dogs are:

  • Exposure to cold or wet environments, such as snow, ice, rain, or wind
  • Inadequate shelter, bedding, or clothing
  • Low body fat or muscle mass
  • Illness, injury, or shock that affect the dog’s circulation or metabolism


Signs of Temperature Distress in Dogs

It is important to recognize the signs of temperature distress in dogs so that you can take appropriate action to help your dog before it is too late. Here are some of the common signs of overheating and hypothermia in dogs:


  • Excessive panting, drooling, or salivating
  • Bright red gums and tongue
  • Increased heart rate and breathing rate
  • Restlessness, agitation, or anxiety
  • Weakness, dizziness, or collapse
  • Vomiting or diarrhea (possibly with blood)
  • Seizures, coma, or death


  • Shivering or trembling
  • Slow or shallow breathing
  • Pale or blue gums and tongue
  • Decreased heart rate and blood pressure
  • Lethargy, depression, or confusion
  • Stiffness or difficulty moving
  • Frostbite on the ears, paws, or tail
  • Unconsciousness or death


How to Keep Your Dog Comfortable in Extreme Temperatures

The best way to prevent temperature-related problems in dogs is to avoid exposing them to extreme temperatures in the first place. However, if you live in an area where the weather can get very hot or very cold, here are some tips on how to keep your dog comfortable and safe:

Hot Weather
  • Provide plenty of fresh, cool water for your dog to drink. You can also add ice cubes to the water bowl or offer frozen treats to help your dog cool down.
  • Provide shade and good air flow for your dog. Avoid direct sunlight and hot surfaces that can burn your dog’s paws. Use fans, air conditioners, or evaporative coolers to lower the temperature and humidity indoors.
  • Avoid leaving your dog in a parked car, even with the windows cracked open. The temperature inside a car can rise rapidly and become deadly for your dog in minutes.
  • If your dog struggles with incontinence on hot days, consider having them wear a lightweight homemade dog diaper to help keep them dry and comfortable.
  • Limit exercise and physical activity on hot days. Exercise your dog in the early morning or evening hours when it is cooler. Avoid strenuous activities that can cause overheating. Monitor your dog for signs of distress and stop if they show any.
  • Use cooling products such as body wraps, vests, mats, or bandanas for your dog. These products are designed to absorb heat from your dog’s body and provide a cooling sensation. You can soak them in cool water and they will stay cool for hours.
  • Ask your veterinarian if you should trim your dog’s hair shorter for the summer. This may help your dog stay cool by allowing more air circulation around their skin. However, do not shave your dog completely as this can expose them to sunburn and skin cancer.


Cold Weather
  • Provide plenty of warm water for your dog to drink. You can also offer warm broth or soup to help your dog stay hydrated and warm.
  • Provide shelter and insulation for your dog. Make sure your dog has a dry, cozy, and draft-free place to sleep. Use blankets, towels, or heated pads to provide extra warmth. If your dog stays outside, make sure their shelter is elevated, insulated, and waterproof.
  • Avoid leaving your dog outside for too long, especially in windy or wet conditions. The wind chill factor can lower the temperature significantly and increase the risk of hypothermia and frostbite. Wetness can also reduce the insulating ability of your dog’s coat and make them lose heat faster.
  • Dress your dog appropriately for the cold weather. Use sweaters, coats, boots, or hats for your dog to protect them from the cold, especially if they have short or thin coats, are small or skinny, or are old or young. Make sure the clothing fits well and does not restrict your dog’s movement or breathing.
  • Limit exercise and physical activity on cold days. Exercise your dog in the warmest part of the day and avoid icy or snowy surfaces that can injure your dog’s paws. Monitor your dog for signs of distress and stop if they show any.
  • Check your dog regularly for signs of frostbite or hypothermia. Pay special attention to their ears, paws, and tail as these are the most vulnerable areas. If you notice any signs of temperature distress, contact your veterinarian immediately.


When to Seek Veterinary Help for Your Dog

If you suspect that your dog is suffering from overheating or hypothermia, you should seek veterinary help as soon as possible. These conditions can quickly become life-threatening and require immediate medical attention. Some of the situations when you should take your dog to the vet are:

  • Your dog’s body temperature is above 105 degrees Fahrenheit (40.5 degrees Celsius) or below 99 degrees Fahrenheit (37.2 degrees Celsius).
  • Your dog is showing severe signs of distress such as vomiting, diarrhea, seizures, collapse, coma, or shock
  • Your dog has signs of organ damage such as blood in urine, stool, or vomit; jaundice; difficulty breathing; irregular heartbeat; or loss of consciousness..
  • Your dog has signs of frostbite such as blisters, swelling, discoloration, or tissue loss on the affected areas.
  • Your dog is not responding to your attempts to cool them down or warm them up.


Well, That’s a Wrap

Dogs can tolerate a wide range of temperatures, but they are not invincible. Extreme temperatures can cause serious health problems for your dog, such as heat stress, heat stroke, hypothermia, and frostbite. 

By knowing how to measure your dog’s temperature, how to recognize the signs of these conditions, and how to keep your dog comfortable in different temperatures, you can help your dog stay safe and happy all year round.
