Avoiding Heat Related Injuries in Dogs (Part II)

When the dog is so heated that it is panting severely, only let it have a few laps of water. Water in the stomach does not cool the dog, you just need to keep the mouth wet so the panting is more effective. Do not worry about hydration until the temp has started down. A dog panting heavily taking in large amounts of water is a risk of bloat. Due to the heavy panting they will swallow air, mixed with a large amount of water they can bloat. Once the temp is going down and panting has slowed to more normal panting then allow water. The dog will rehydrate it self after temp is normal. If the dog has a serious problem and even though you have gotten the temp normal, get the dog to a vet, as it can still need IV fluids and some
medication. Also, a case of heat stroke can induce a case of hemorrhagic gastroenteritis (not parvo), with a ton of very bloody diarrhea and a lot of fluid and electrolyte loss. These cases need aggressive treatment.

The best method of treatment is prevention. Learn to watch your dog, and see the changes in the size of the tongue, and how quickly it goes down. Learn your dogs response to the different environments, and be careful when you head south for an early season hunt test or trial. I have been to Nashville at the end of May, only 5 hours away, but the difference in temp and humidity did effect the
dogs as they were used to more spring weather in Ohio. Try different things in training to help the dog cool and learn what works better. Another very important point=> Do not swim your hot dog to cool it then put in put in a box/tight crate. Remember, evaporation can not take place in a tight space, and the
box will turn into a sauna and you will cook your dog.
Carry a stake out chain, and let the dog cool and dry b
efore putting it up.

I demonstrated this lesson this spring with my 10 monthold pup.
After doing a 15 minute session in yard drill on a warm 70+ degree day, she was panting pretty hard and was pretty hot. She was OK but it was time to stop. Just for the heck of it I took her temp. She was 103.6, above normal but too bad for a dog that had just finished working. In my back yard I have a 300 gallon Rubbermaid tub filled with water. I took her to it and she jumped in and out 3-4
times. She appeared totally improved, tongue was much smaller, and eyes brighter and her full spring was back into her step. So I re-took her temp and it was 104.2, so even though she looked better she was hotter. This is a perfect lesson to show not get a hot dog wet and then put them in a box. The water on her skin caused the blood vessels to constrict, decreasing blood flow to the skin.
Therefore the hot blood was shunted back to the dog's core and retianed the heat. You may have felt the same thing, after exercising but still being very warm, take a shower and get cooled off but as soon as you turn the shower off you start sweating again.

I know this is s bit long, but hopefully this is easy to understand and helps provide some useful information. Remember: Prevention, learn your dog. It is worth the time and effort.
