That graph is not very readable, you are right. Since I don't have a unit to measure the dog's behavior changes, this is reflected in the graph

Your solution to not having a unit is graphing it with an unreadable scale???

Looking at the author's other posts: Very prolific, long articles, and weird outliers like https://lightcapai.medium.com/should-i-go-milan-211ef725bb71, https://lightcapai.medium.com/if-you-are-suicidal-read-this-..., and https://lightcapai.medium.com/alpay-algebra-solving-the-unso... (a weird take on the halting problem).

Yeah, they're mostly fluff. Based on the title I'm a bit disappointed there wasn't more actual science here, like measuring bacterial content changes in the stool.

While I don't doubt the perceived changes and there is plenty of human research indicating that gut bacteria dictates more about us than we'd like to admit the graphs in this article definitely portray the results as having more rigor than they actually did.
