Unfortunately, judges aren't the neutral arbitrators that the system paints them to be. They're employed by the government just like the cops and the prosecutor, and they're often former prosecutors themselves. The implicit bias should be obvious, but even if it wasn't, the amount of times they bend over backwards to hand a win to the government would clue anyone in.

In a fair world the judge would have said: "Hand me a list of every officer who claims that they believed he was asking for a literal dog. For the rest of their careers anytime they give testimony or have evidence they collected presented to the jury, there will be a mandatory notification that they are fucking idiots and anything they say or do should be placed in that context."

I was using hyperbole for effect, but yes. I am aware there is a specific way you must invoke your rights. Which is stupid because you don't lose your rights because you don't know the magic incantation, but government gonna government.

Actually they rejected his appeal because saying "maybe I should talk to a lawyer" isn't invoking your right to a lawyer so when he said "why don't you just give me a lawyer dog" it was the "why don't you just" that was the reason they denied his appeal and quoting "lawyer dog" was just them mocking the defendant.

But, yeah, don't try to be cute when asking for your lawyer. Ask for a lawyer and just keep asking if they don't stop.
