As veterinarians, it's heartbreaking that every summer we see several cases of heatstroke. These are dogs that are members of the family. They are loved and cared for by well-intentioned owners that dote on them. They just thought that their dog loves to ride in the car and that they would be fine in the car with the windows cracked while they ran into the dry cleaners. Or they perhaps didn't realize that they were putting their beloved pet in danger by taking them for a run or a walk on a summer day. Don't let this happen to you! Read the following tips on recognizing and preventing heatstroke in your dog to keep them on the path to wellness.

Why do dogs get heatstroke?

Dogs will not tell that they are too hot and that they need to stop for shade and water. Going on car rides, playing outside, running around the park, or going on a walk with you is what they live for. It is hard to tell if a dog is just panting from excitement and a little exertion or if they are in distress from the heat. A dog will just keep going and going and going until they drop. It is our job as a responsible, dedicated, and loving guardians to protect our dogs from heatstroke.

How do dogs get heatstroke?

Dogs and humans regulate body temperature differently. Humans sweat and, as it evaporates from our skin, we cool off. Our four-legged family members have some sweat glands in the footpads, but that does not cool them off in extreme conditions. They cool off by panting. If we get too hot, we stop what we are doing and find a way to cool off. If they get too hot they will keep going and overheat. This can be fatal if not corrected quickly.

How can you prevent your dog from getting heatstroke?

As veterinarians, we can tell you that heatstroke happens, even in the cases of extremely astute pet owners.

That's why it's important to consider what you can do to prevent heatstroke, and some of those means of prevention are below:

  • Do not leave your pet in a parked car during the warmer months, even on mildly warm days. Even if you leave the windows cracked, temperatures can rise to deadly temperatures in minutes.
  • Have water available at all times. Make sure to bring water for both of you when on a walk or hike and offer it frequently.
  • Make sure there is shade available if you go outdoors when it is hot outside.
  • Even if your pet is indoors, you still need to protect them from high temperatures. Consider leaving the air conditioner on a low setting and keep the blinds and shades pulled down to keep the house as cool as possible.
  • Be mindful of the time of day that you take your pet out. Take them out in the morning and evening so that they stay as cool as possible and do not burn their paws on the cement. Place your hand on the cement to test it out. If it is too hot for you to hold your hand there, it is too hot for their paws.

What are the signs that a dog is having heatstroke?

Some signs of heatstroke in dogs will be very visible while others can be more subtle, which of course makes them all the more dangerous.

Common signs that your dog might be having a stroke include:

  • Uncontrollable heavy panting
  • Quiet or poorly responsive; may lay down and refuse or be unable to rise
  • Loss of balance, head tilt
  • Pacing, circling, or turning the wrong way when called
  • Abnormal eye movements or facial expressions
  • Impaired vision
  • Confusion
  • Loss of control over bladder and bowels
  • Vomiting Collapse, loss of consciousness
  • Rectal temperature of over 105 degrees 

What do I do if I recognize heatstroke in my dog?

If you suspect your dog has or is in danger of developing heatstroke, you will need to take action fast. Remove your pet from the heat and to take them indoors or find shade. Then you’ll want to lower the body temperature as quickly as possible. The easiest way to do that is to put your dog in the bathtub and run cool water over him, especially the back of the neck. Do not use COLD water. It can cool your dog too rapidly.

Contact a veterinarian or the nearest pet emergency hospital immediately! You will need to get your pet to a veterinarian as soon as possible!

The main medical treatment for heatstroke is the administration of IV fluids and electrolytes, as well as continued efforts to cool the pet. Blood work (CBC and chemistry values, along with clotting times) are likely to be run to make sure no further treatment is needed.

When dealing with heart stroke swift action is vital, but it is completely avoidable if you are aware of the dangers and prevent it altogether. If you have further questions about how to prevent this potentially dangerous condition in dogs, please give us a call.
