I could certainly use some audio with this. It's hard to learn the characters and the words without it I think
I also agree that it should, especially because they didn't teach the word prior to that.
For me part of the issue as a zero-knowledge beginner is that I dont know if it's "wa inu" after the first Kanji or "hai nu." How do you tell those potential clashes apart? Just experience, probably?
Well, besides the missing corner brackets (used as quotation marks in Japanese), his sentence is fine; it just says "犬 is the kanji for dog".
