I am told that dogs sweat through their tongues, if that is true, then the above is the question.

and their paws

They don't sweat through their tongue... they lose  through their tongue, which is wet. They don't have sweat glands on their body.

Dogs can quickly be hurt if they do not have enough water in the heat. They pant to try to cool off as Carol said. They do not have sweat glands. A dog cools off in water and with water shade etc.. If they are not drinking and provided with adequate shelter from the sun they could die from heat stroke very easily..They get limp and dehydrated and then they can't even take in the water on their own anymore.. it is sad to see a dog who is in this condition!

My reply is going to be basically the same. Dogs cool off w/ their tongues, the wetness is like the wetness in our own mouths.

  Dogs have the ability to sweat, but in places that are a little different from humans. Dogs sweat through their pads and feet. Their skin and armpit areas don't contain sweat glands like ours do. Their main method of ridding themselves from heat, however, is by panting, which is a very different mechanism than what we generally use.

For these reasons, we must take great care to protect our dogs from heat stroke. Dogs with compromised respiration, like bulldogs and pugs, are at a very high risk of easily overheating just because they can't pant very efficiently.

Perhaps they use a deodorant.

Well, it is a thought.

I think it should be mentioned that dogs do not actually have arms and, therefore, cannot have armpits.
