The first key is hydrate, hydrate, hydrate. Make sure your dog has plenty of fresh, cool water accessible at all times. For a special treat, add a few ice cubes once in awhile.
Next, limit the amount of time your dog spends outdoors. The best solution is to keep the dog indoors as much as possible, but if you simply have to keep your dog outside for an extended period of time, please make sure to provide shade.
For dogs with short hair or no hair, provide protection from sunburn, either with sunscreen or by keeping the dog out of direct sun during the most dangerous part of the day (10 am to 4 pm).
If you have a neighbor who leaves a dog outside, check frequently to see that proper water and / or shade is provided. If not, you might make the suggestion to the person, and if there is no improvement call your local animal control office or humane society.
Pray for lower temps!
Until next time,
Good day, and good dog!
