The plural form of a wolf is:

In Noun-Number, there are two types of numbers: singular and plural. A noun that refers to multiple individuals or objects is said to be in the plural. A singular noun is one that only refers to one individual or object. Wolfs, wolfes, and wolfoes are terms which cannot be found in dictionaries. They have no meaning because they are only random plural forms that were formed by adding -s or -es. As a result, the choices for wolfs, wolfes, and wolfoes are incorrect. The plural form of the majority of English nouns that end in 'f' is 'ves.' The plural of a wolf is created by dropping the letter "f" and replacing the letter 'ves'; hence wolves are the plural of a wolf.
