grammar - How can I identify a word that ends with "-ing" as being a noun, a verb, or an adjective?

How can I distinguish between words which have the -ing in a sentence that are nouns, verbs, or adjectives?

For example sometimes -ing come with word to give us a noun, and sometimes a verb or an adjective.

That interesting snake.
That crawling snake.
That barking dog keeps everyone awake.

Is there any rule to determine whether a word with -ing is a noun, verb, or adjective?
