Updated: 24/05/2017 – As a heat wave hits the UK

Felt it was right to resurrect this post in time for summer 2017. Good to spread the message every year.

Would you put a baby in the oven?
When people leave dogs in hot cars, this is exactly what they’re doing.

5 reasons why leaving dogs in cars, even on a mildly warm day is a bad idea:

  1. Mild days and car temperature are deceiving
  2. Car temperature increases with time
  3. Cooking canines in cars leads to heatstroke
  4. Cranked windows make no difference
  5. The sun doesn’t have to shine

What to do if you see a dog suffering in a locked car
The consequences of a dog dying in YOUR car.

#1: Mild Days and Car Temperature are deceiving

Even on a balmy day when the air temperature is a pleasant 21ºC, it only takes 60 minutes for the temperature inside a car to reach a blood-boiling 46ºC.

Why does this matter?

Because when a dog’s core temperature reaches 41ºC his blood becomes so thick it can’t circulate properly, he suffers organ failure, and dies. In short, even on a mild summer’s day dogs die in hot cars from heat exhaustion.

#2: Car Temperature Increases with Time

There’s a reason recipes tell you to pre-heat the oven, and this is because the temperature rises with time. This is just the same with a car because after 60 minutes the temperature inside can be 4.4ºC (or 40ºF) hotter than outside. When you bear in mind that heatstroke in dogs occurs at core body temperatures around 41ºC (normal temperature 39.2ºC) and you begin to glimpse the problem.

Let’s take a look at this in terms of a summer’s day.
• 21ºC air temperature, after 60 minutes the car temperature is 46ºC
• 26ºC air temperature, after 60 minutes the car temperature is 52ºC
• 32ºC air temperature it takes just 30 minutes to reach 48ºC inside a car

“It’s easy to see the danger. You just have to touch the dashboard or seats to know how hot the inside of a car can get.” Mark Spowage. AA Patrol of the Year.

#3: Cooking Canines in Cars leads to heatstroke

It’s 24ºC outside, jeans and T-shirt weather. On the drive home from the dog park you remember you’ve run out of nappies so you stop off. The superstore doesn’t allow dogs inside so you crank open the car windows, grab the baby, but leave the dog as he’ll fine for ten minutes.

Unfortunately, the baby needed a change and there was only one till open with a huge queue, and the ten-minute errand took half-an-hour. By this time the temperature inside the car has climbed to 42.7ºC

Guess what?
Your dog now has heatstroke.

To understand how easy it is for a dog to suffer heat stroke in a car, here’s a quick quiz.

QUESTION: What’s your best guess for the temperature inside an oven at Gas Mark 1/4 (say, to cook meringues)?

Is it:
a) 90ºC
b) 110ºC
c) 140ºC

ANSWER: The cook’s amongst you will know the answer is (b) 110ºC, which is also high enough to give a dog heatstroke… and this is GM ¼!

Heat Stroke Symptoms in Dogs

From going on holiday to trips to the park, traveling with a dog in the car is inevitable. Tops tips for keeping your canine cool include:

  • Put the air con on
  • Wind the windows down a little (However, don’t allow the dog to stick his head outside through an open window.)
  • Take water and stop for frequent breaks
  • Take towels and plenty of water to soak your dog should he overheat

Remember wearing a fur coat inside a warm car can lead to heat distress, so what are the signs to watch for?

  • Heavy panting
  • Drooling
  • A distressed facial expression
  • Rapid, heavy breathing
  • Confusion and disorientation
  • Shaking despite the heat
  • Red gums or mucous membranes
  • The dog feels hot
  • Weakness and collapse
  • Loss of consciousness

Heat Stroke in Dogs: Action and Prevention

If your dog has heatstroke it’s imperative to act fast in order to cool him down.

  • Offer water to drink
  • Don’t exert him. If necessary, carry (rather than walk) him to a cool place
  • Wet his coat, paws, and tongue with cool (not freezing water)
  • Blow cool air from a fan over him

If the dog seems drowsy, unsteady on his feet, or isn’t improving within five minutes then seek urgent veterinary attention.

If you want to know why do dogs die in hot cars it’s because heat causes blood to thicken. This makes the circulation sluggish and key organs such as the brain and kidneys quickly become deprived of oxygen. In a worst-case scenario the dog can go into organ failure and die within minutes, which is why you should never leave your dog in a car in warm weather, even for a few minutes.

Remember, all it takes is a car the same temperature as a cool oven to cook meringues and your dog could be dead.

#4: Cranked Windows make No Difference

According to the American Veterinary Medical Association (AVMA) hundreds of pets die each year, from being left alone in hot cars. The trouble is, many of these dead dogs belonged to owners who believed that leaving the window open ajar meant their dog would be fine.

They found out the hard way they were wrong.

#5: The Sun doesn’t have to Shine

Likewise heatstroke in dogs doesn’t just happen when the sun shines. What matters is how hot it is outside; It’s the temperature that counts, so even when parked in shade or on an overcast day, a car acts like a greenhouse and it gets hotter and hotter inside.

“48% of people who leave their dog in a car in hot weather believe its OK because they’re parked in the shade of the window is open.” Dogs’ Trust survey

What to do if you see a dog locked in a car

  • Try to find the owner of the car. Public announcement in the supermarket always works well.
  • If the owners of the car cannot be contacted, contact the police on 999 to attend the vehicle.
  • You should not take any action to gain access to the car without first speaking to the police. Always take images/footage of the dog and the names and numbers of witnesses to the incident. The law states that you have a lawful excuse to commit damage if you believe that the owner of the property that you damage would consent to the damage if they knew the circumstances (section 5(2)(a) Criminal Damage Act 1971).
  • If a dog has been in a car for even a short time it may need its temperature brought down slowly by drinking and through cooling the body. We would recommend seeking veterinary advice on this if the animal is in distress.infographic on preventing dogs dying in hot cars

The consequences of a dog dying in YOUR car

If a dog suffers or dies as a result of being left in a hot car, their owner, or the person for the time being in charge of the dog, can be prosecuted for neglect or cruelty under Animal Welfare Act 2006  and could face jail time, fines and being banned from keeping animals in the future.

Please, don’t let this be you!!!
