-ChatGPT initially gives the same diagnosis the vets did, Babesiosis
-It notes that Babesiosis may have either been a misdiagnosis or there may be a secondary condition/infection causing the remaining symptoms after the Babesiosis treatment didn't resolve all of them
-It suggests such a hypothetical secondary condition could be IMHA, which the article notes is an extremely common complication of Babesiosis with this specific dog breed
-A quick Google search brings up a fair amount of literature about the association between Babesiosis and IMHA
So in fact this is the opposite of a never before seen situation, ChatGPT was just regurgitating common comorbidities of Babesiosis and the vets in question are terrible at their job.
