It is not a logo of the "dogecoin doggy". It is doge, a very popular meme which Elon seems to enjoy.

I think the change occurred because of someone's request on his recent Twitter spaces discussion about the algorithm release. Near the end a participant asked about the "Fail Whale" being brought back because it had personality and she missed it. He said he would see about it. So perhaps he wanted to find out what the process would involve for modifying the site's logo.

Paraphrasing Matt Levine… everything is securities fraud. So yes?

I doubt it, but it's still shaping up to be an embarrassing self-troll. Maybe in a few days Elon will have a good alibi, or perhaps a Tesla-branded time machine headed back to an age when this would be novel or funny.

of course

The Doge meme proceeded before Dogecoin.

If it was the 'Dogecoin logo', you would have a point. But it is an image of the doge meme.
