With the big swings in temperature here in the Northland it can be extremely stressful on dogs as they do not have gradual acclimatization opportunities. Going from 35-86F can be deadly.

Our sled dogs are bred specifically to thrive in the coldest temps on earth within reason. They may not look like it but they really suffer in the heat. We do NOT exercise any of our sled dogs unless it’s below 60F and 50% humidity. Harness training doesn’t start until it’s below 50F.

Here are some tips for you to recognize some heat stress symptoms with your dogs.

Symptoms include heavy panting, excessive drooling, bright red or pale gums, restlessness, and in severe cases, vomiting, diarrhea, seizures, or collapse. A dog’s body temperature can rise significantly during heat stress, potentially leading to heat stroke, a life-threatening condition.

Early Signs of Heat Stress

  • Excessive Panting:
    Panting is a normal way for dogs to regulate their body temperature, but heavy or rapid panting, especially when not exercising, can be a sign of overheating.
  • Excessive Drooling:
    Increased drooling can be a sign of the dog’s attempt to cool themselves down.
  • Bright Red or Pale Gums:
    A change in the color of the gums can be a subtle but important indicator.
  • Restlessness or Agitation:
    Dogs may become restless, pacing or seeking shade, as they try to find relief from the heat.

More Severe Signs of Heat Stress

  • Vomiting or Diarrhea:
    These can indicate the body is struggling to cope with the stress of overheating.
  • Lethargy or Weakness:
    A dog that becomes lethargic, weak, or uncoordinated may be struggling to regulate their body temperature.
  • Seizures or Collapse:
    In severe cases, dogs may experience seizures or collapse due to the strain on their body.
  • Elevated Body Temperature:
    A rectal temperature of 104-106 degrees Fahrenheit is a sign of heat stress, while a temperature of 106 or higher indicates heat stroke. Normal temperature for a dog at rest is 102.1F.

If you suspect your dog is experiencing heat stress, it’s crucial to act quickly.

  • Move your dog to a cooler environment.
  • Cool your dog down with water.
  • Apply cool water to their body, especially around their ears, paws, and belly.
  • You can use a bag of frozen peas or an ice pack on the back of their head.
  • Continue to monitor their core temperature.
  • Seek veterinary attention immediately.

The health and safety of your dog should always come first — and that means respecting their limits in extreme weather. Whether you’re caring for a backyard companion or a hardworking sled dog, knowing the signs of heat stress could save a life. Stay alert, plan ahead, and when in doubt, keep things cool.
