- Alternate Character Interpretation: Given how fast he tends to forget and misinterpret a lot of things, is Hank simply a Genius Ditz, or perhaps experiencing early stage dementia?
- Big-Lipped Alligator Moment:
- After the books started to include two songs per book, every once in a while a song would become this. Two good examples are the Saddle Up Overture in C Maybe and Where Were We?
- Drovers Secret Life is an extended books, but the extra chapters do absolutely nothing to the plot. Justified in that it fits Drovers personality.
- Harsher in Hindsight: In one book, a wild fire almost destroys the ranch. This later actually happened to the Author.
- Moral Event Horizon: Tuerto in the eighth book crosses this when he tries to trample Amy and Ashley. Unlike the previous incident with Hank and Drover, the girls weren't even bothering him; it seems like he wanted to harm them just because he could.
- Periphery Demographic: Erickson initially wrote the books for adults. He was a little surprised when he discovered that it was mostly kids that were the ones who were reading them. But he ran with it, and is still going strong today.
- Nausea Fuel: In A Dog's Life we learn what happens when Buzzards get mad. "They throw up on the party that made 'em unhappy". Which is gross enough, but then you take into account what a Buzzard's diet consists of... Yeah (also Truth in Television). Let's just say that Rip and Snort learned a very important lesson in that book. Hank himself was so grossed out that in later books he refuses to even talk about it. This gets a repeat performance in The Case of the Prowling Bear, when he tries to hit Hank with it after being forced to say, "Thank you."
YMMV / Hank the Cowdog
