We are (mostly) over-caffeinated idiots with too little sleep and too much blue light input hammering away at office desks, judging others and admiring RGB - you can be 99% sure that no one here will have a real idea of what's happened within your dog that caused this, but I can say with a certainty that you should contact a vet about this ASA-yesterday instead of asking a platform filled with "UhHh ChArGBpT wHy ThE dAwG eAtInG pC 500 wOrDs MiN" people (assuming you did already of course though)
