Dog Health & Care

Heat Exhaustion Dogs Vomiting

Now that spring is here and summer is right around the corner, we need to begin watching for dogs developing heat exhaustion–dogs vomiting, bright red tongue, extremely thick saliva,  difficulty in breathing, heavy panting, walking in strange patterns, collapsing, disorientation, bloody diarrhea, and eventually becoming unconscious.  The result is that many dogs either die or become ill enough to require massive medical care.

Global warming is making the weather patterns erratic and the temperature much hotter than normal, so any heat temperature over 105-degrees will begin to cause the animal problems, with 108 to 110-degrees affecting the heat stroke dog and its organs, possibly causing some pretty bad damage to its cells. Any owner can face dog heat exhaustion in the summer if its owner does not fully understand the animal’s mechanism, with heat exhaustion, dogs vomiting the number one area to watch for.

How Dogs Can Develop Heat Stroke

When a dog begins to develop heat stroke, watching for symptoms in advance may save its life.  With heat stroke occurring within minutes in an animal, it is important to recognize the symptoms in dog’s heat exhaustion—dogs vomiting, excessive drooling, rapid or excessive panting with a wide or glazed stare, lethargy or weakness, very hot or dry skin, the gums in the mouth will appear pale and dry, with eventual loss of consciousness.

First Aid for Heat Stroke in Dogs

  • The most important prevention for heat stroke is to not leave any dog or puppy confined during the hot times of the year in a car, crate or dog house.

  • If you find that your dog is succumbing to heat stroke, remove it  immediately from their heated surroundings and place them in nearby shade.

  • Do not allow the heated dog to gulp cold water. Offer them small amounts of cool water.

  • Place them in a pan of cool (NOT COLD) water so their feet are submerged. Bathe their face, chest, groin area, and stomach with the cool water very gently.Cold or ice water will cause their vessels to constrict and prevent the body from cooling.

  • Before calling a vet, take the dog’s temperature anally as it will be more accurate to give this information over the phone.

Body Temperature in Dogs with Heat Stroke

When cooling the body of the over-heated dog, do not wrap the dog’s body with wet blankets or towels. This method will keep heat inside the body. Instead, pat the body or gently drape a wet towel over the back, or hold ice packs for short periods in the groin or under the arm pit areas.

As fast as the body as risen in temperature, they can become chilled just as quickly. It is always important to monitor the body temperature of a dog with heat stroke very carefully. Normal temperature is 101 to 102 degrees. Heat stroke occurs at 104 degrees, with dire emergency developing at 106 degrees. Chilling is when the body is too cold, and drops below 101 degrees. When the body becomes chilled, remove the wet towels and ice bags.

Meanwhile, take the animal to the vet if nothing seems to be working. When transporting the ill dog to the vet, definitely do not place it back in a crate. To help the body cool down, make sure the windows are down or have the air-conditioning on high unless they are chilling. Then keep the air-conditioning off.

Important Things to Know About Dogs on Hot Days

  • To not leave them alone in a car for hot weather regardless how far down the windows are rolled. This is the number one reason for heat stroke in dogs, with many suffering and dying even on mild days.
  • It is important to remember even if it is under 80-degrees outside the vehicle, it will be over 90-degrees inside when in the shade and over 160-degrees if the car is in the sun.
  • Fifteen-minutes is all it takes for a dog to go down with heat stroke in this type of surrounding with heat exhaustion, dogs vomiting or developing severe panting just a start for the fast-moving heat stroke symptoms in the dog to develop.
  • If you see any dog, animal or child in a parked car in such weather, then do what it takes to remove them in order to save their lives. Look around to see if the owner of the vehicle is nearby. If not, immediately take down the car’s  information—color, model, make, license number, and its location.
  • Quickly enter nearby stores or public buildings, and page the owner with the car information. If nobody answers, then call the authorities. The heat-stricken dog will go down by the time you are finished if you move to slow.

In addition to being left in a vehicle in the summer, dogs that are confined on concrete runs without shade will also quickly go down due to severe heat stroke, especially if the dog is a short-nosed breed (Pugs, Boxers, Bull Mastiffs, Japanese Chins, Pekingese, or Bulldogs).  People who take their dogs to a groomer during the summer also need to make sure their dog is not muzzled while placed under a dryer, as it it dangerous and can be life threatening–especially if the dog suffers from airways disease or has a physical condition that impairs their breathing.
