Dogs die in hot cars


Don’t let your dog get heatstroke – it can be fatal
It’s that time of the year again, and already dogs have died from heatstroke.
What is heatstroke?
In simple terms, heatstroke occurs when a dog loses its natural ability to
regulate its body temperature. Dogs don’t sweat all over their bodies the way
humans do. Canine body temperature is primarily regulated through respiration
(i.e., panting). If a dog’s respiratory tract cannot evacuate heat quickly
enough, heatstroke can occur.
To know whether or not your dog is suffering from heatstroke (as opposed to
merely heat exposure), it’s important to know the signs of heatstroke.
A dog’s normal resting temperature is about 100.5 to 102.5 degrees Fahrenheit.
Once a dog’s temperature rises above 105 degrees, physiological changes start to
take place, and the dog begins to experience the effects of heatstroke. At 106
to 108 degrees, the dog begins to suffer irreversible damage to the kidneys,
liver, gastrointestinal tract, heart and brain.
If a dog is experiencing heatstroke, you may observe excessive panting;
hyperventilation; increased salivation; dry gums that become pale, greyish and
tacky; rapid or erratic pulse; weakness; confusion; inattention; vomiting;
diarrhoea; and possible rectal bleeding. If the dog continues to overheat,
breathing efforts become slowed or absent, and finally, seizures or coma can
occur.
The amount of damage a dog sustains when stricken with heatstroke depends on the
magnitude and duration of the exposure. The longer and more severe the exposure,
the worse the damage will be.
What to do
1. Pay attention to your dog. Recognizing the symptoms of heatstroke and
responding quickly is essential for the best possible outcome.
2. Get into the shade. If you think your dog is suffering from heatstroke, move
it into a shaded area and out of direct sunlight. Apply cool water to the inner
thighs and stomach of the dog, where there’s a higher concentration of
relatively superficial, large blood vessels. Apply cool water to the foot pads,
as well.
3. Use running water when possible. A tap or hose is the best way to wet down
your dog’s body. Never submerge your dog in water, such as in a pool or tub –
this could cool the dog too rapidly, leading to further complications, including
cardiac arrest and bloating.
4. Use cool – not cold – water. Many people make the mistake of using cold
water or ice to cool the dog. When faced with a dog suffering from heatstroke,
remember that the goal is to cool the dog. Using ice or extremely cold water is
actually counterproductive to this process because ice and cold water cause the
blood vessels to constrict, which slows blood flow, thus slowing the cooling
process.
5. Don’t cover the dog. One of the keys to successfully cooling your dog is
ensuring the water being placed on the dog can evaporate. Never cover an
overheated dog with a wet towel or blanket. This inhibits evaporation and
creates a sauna effect around your dog’s body. Likewise, don’t wet the dog down
and put it into an enclosed area, such as a kennel. Any air flow during the
cooling process is helpful in reducing the dog’s body temperature. Sitting with
the wet dog in a running car with the air conditioner blowing is an ideal
cooling situation.
6. Keep the dog moving. It’s important to try to encourage your dog to stand or
walk slowly as it cools down. This is because the circulating blood tends to
pool in certain areas if the dog is lying down, thus preventing the cooled blood
from circulating back to the core.
7. Allow the dog to drink small amounts of water. Cooling the dog is the first
priority. Hydration is the next. Don’t allow the dog to gulp water. Instead,
offer small amounts of water that’s cool, but not cold. If the dog drinks too
much water too rapidly, it could lead to vomiting or bloat.
8. Avoid giving human performance drinks. Performance beverages designed for
humans are not recommended because they are not formulated with the canine’s
physiology in mind. If you can’t get an overheated dog to drink water, try
offering chicken- or beef-based broths.
See a vet
Once your dog’s temperature begins to drop, cease the cooling efforts and bring
the dog to a vet as soon as possible. Your dog’s temperature should be allowed
to slowly return to normal once cooling has begun. A dog that’s cooled too
quickly may become hypothermic.
Even if your dog appears to be fully recovered, the vet needs to check to
determine if the heatstroke caused any damage to your dog’s kidneys and liver.
The effects of heatstroke can continue for 48 to 72 hours longer, even if your
dog appears normal.
William Grant, DVM, a vet for 20 years and former president of the Southern
California Veterinary Medical Association, has treated hundreds of cases of
heatstroke, ranging from mild to fatal.
According to Grant, the most common cause of death following heatstroke is
disseminated intravascular coagulopathy (blood coagulating throughout the body),
or DIC, which can occur hours or days after the heatstroke episode.
DIC can also be caused by pyometra or septicemia, but Grant says heatstroke is
the most common cause. “Once a dog develops DIC, it may bleed in the thorax,
abdomen, nose and intestine,” Grant says. “Once the blood-clotting factors are
consumed, there is an inability of the blood vessels to prevent leaking; the
condition is almost always fatal.” For this reason, follow-up veterinary care is
essential following a heatstroke episode, even if your dog seems to be
completely fine.
Prevention is the best medicine
The best treatment for heatstroke is prevention. Especially during the summer
months, it’s essential to be aware of the potential for heatstroke. Knowing the
signs of heatstroke, and taking the necessary steps to prevent it, will ensure
your dog can have a safe and active life year-round.
And don’t forget: DOGS DIE IN HOT VEHICLES!!

  1. Excellent advice and very informative. So many people don’t employ even basic common sense when it comes to dogs and cars it’s unbelievable.

    • arlene

      Thank you Wolfie, it always worries me when I see a dog or dogs in cars in the heat, I try and hang around to make sure that the owners come back, one day I’ll be had up for loitering LOL,

  2. CatsRuS

    Great advise Arlene, it’s amazing the amount of people who don’t think and leave their dogs and even cats in hot cars. I don’t know why they think an animal can stand the heat any better than a human can.
    How’ve you been btw, hope all is well with you. I’ve decided to start blogging again shortly, after being away for so long.
    Bye for now. 🙂

    • Hi Robyn, nice to see you on here and hear from you again.
      I’m well and have had such a busy Easter plus catching up with planting the garden, I’ve also been a bit neglectful of visiting, I hope to get back on track sooner rather than later. keep me posted.

  3. curiosity abounds

    Very timely advice and some tips there that I am glad off. Makes sense about wet towels not being good on dogs, must stop doing that at dog shows in the heat which is common practise.

    • Hi Anne, thanks for visiting, and I am so glad that you found something useful in the article, it’s surprising how much we ‘dogpeople’ think we know, but, something crops up and we realize we’re not so savvy after all. I too found the advice very enlightening.
      I remember during the heatwave in the 70’s the news showed pictures of a man who came back to his car to discover both his Rotties had succumbed, his beartbreak was obvious sitting by the side of the car with the dogs in his arms sobbing his heart out, the image has never left me.
