today on overthinking the trading card anime
So the whole Kaiba-calling-Joey-a-dog thing is pretty infamous, to the point that it’s the source of their ship name. And the dub may have played it up a little, but it’s still definitely a thing in the original.
Which is why it’s notable that in the subs, there’s one other time that Kaiba brings up dogs:
When he’s talking about himself in relation to Gozaburo.
And we get the same connection in the manga, too, with this panel of Gozaburo (literally or metaphorically? it’s all in Mokuba’s head, so it’s a little hard to tell) forcing a young Seto to wear a dog collar.
There’s definitely some interesting stuff we could take from this. We could be dealing with an example of the classic “abused kid becomes a bully by turning their abuser’s tactics on other people” (and if we take some of the stuff Kaiba says to Joey as paraphrased versions of things Gozaburo said to mini!Seto…ouch). But it’s also interesting to look at in the context of Joey and Kaiba as foils.
