- Keep Circulating the Tapes: A subbed version of the anime was put out some time ago that was much better than the infamous blue subtitles version. However, since the website has since shut down, the only place to find this subbed version is on YouTube. It should be noted the first half (Episodes 1-10) were done by one sub group and the rest of the episodes (Episodes 11-21) were done by a different group using the same formatting.
- Old Shame: The Wolf Arc. The only reason it came to be was because Takahashi was told to keep on drawing the series and he has all but pretended it didn't even exist in his later works.
- What Could Have Been: Before Takahashi settled on using wolves for the second story arc of the manga, his publisher suggested a new Big Bad bear named Aokabuto, but Takahashi refused to do it.
- Also known as Silver Fang in most dubs and Hopeanuoli in the Finnish dub.
