Not all dogs do, your dog can probably taste where another dog has had a wee. Also, sometimes salt, and oils are left from whatever has evaporated, food, liquids, even where someone was sweating. Anything that will leave a residue, a dog's keen nose will sniff it out and he is going to investigate with his tongue. If he's got nothing else to do, and he likes the scent, or taste he will contintue to lick and sniff. Make sure there are no harmful chemicals near by, such as anti-freeze, which tastes sweet and is extremely dangerous, and even charcoal dust especially with the lighter fluid already in the bricks, can be dangerous as well. I'd recommend you just clean the concrete off with water on a regular bases and keep an eye on your pet.
