The Call of the Wild: English level and reading difficulty
Short and dramatic, but its vocabulary coverage is the lowest of the new books here. Dog-sledding terms, animal sounds, and miners’ slang appear on almost every page. Our recommendation for the complete original is Upper B2.
Updated
Short answer
Recommended level: Upper B2
Yes for upper B2, and it is short enough to finish in a week. B1 learners often underestimate it because of its length. The specialist vocabulary makes it harder than it looks, so prepare the key words first.
Original versus graded reader: Graded versions usually simplify the animal-sound verbs and remove miners’ slang. This page analyzes the complete original in Project Gutenberg ebook 215.

Vocabulary profile
How much of the original vocabulary falls in each frequency band?
The bars show the share of running word tokens—not the share of unique dictionary entries. Common words repeat often, so token coverage is the more useful signal for how frequently a learner may meet unfamiliar language while reading.
A181.35%
A26.69%
B15.36%
B22.52%
C11.17%

Unlisted1.59%
These are TeakReader frequency-based vocabulary bands, not official CEFR assignments for every word or an official CEFR certification of the book. They are most useful as comparative reading signals.
Beyond the percentages
What makes The Call of the Wild difficult?
- The story is told from a dog’s point of view, with many verbs for animal sounds and movement (snarl, whine, yelp, bristle).
- Dog-sledding words such as “sled,” “harness,” and the commands “mush” and “gee” are central to the plot.
- Gold-rush miners speak in slang and dialect, for example “wot” and “grub.”
- Only about 93% of running words fall within the B1 band, lower than most books on this list.

A practical reading plan
How to read the original without losing the story
- Learn the sled and animal-sound words first; they repeat throughout the book.
- Remember that Buck is a dog. Reading “he” as Buck avoids a lot of confusion.
- Read one chapter at a time; there are only seven chapters.
- Reread fight and journey scenes after checking key verbs; they carry the story.
Transparent methodology
How we estimated the English level
We downloaded the UTF-8 plain-text edition from Project Gutenberg ebook 215, removed the standard Gutenberg header and footer, lowercased English word tokens, and matched them against the same ranked frequency data TeakReader uses for vocabulary analysis. We then combined token coverage with editorial review of syntax, narration, dialect, historical context, and wordplay.
Vocabulary coverage is informative but not a complete readability score. Research on reading comprehension commonly distinguishes knowing most running words from understanding every sentence; syntax and background knowledge still matter. See this Cambridge overview of lexical coverage research for context.
Limitations: proper names, contractions, dialect spellings, and inflected forms can be classified as unlisted. Different editions and translations may produce different counts. The recommended level is TeakReader’s evidence-informed estimate, not a score issued by the author, publisher, Council of Europe, or Project Gutenberg.
