It isn't, at all. It's just one of many little details. I wrote more in some other comments in this thread. For example:

Here are the dog references, for anyone else curious:
(Alleged Virginia attack)
>Then, shortly after Thanksgiving 2019, according to three sources familiar with the incident, a White House staffer was hit while walking her dog in Arlington, Virginia, a suburb of Washington, D.C. According to a government source familiar with the incident, the staffer passed a parked van. A man got out and walked past her. Her dog started seizing up. Then she felt it too: a high-pitched ringing in her ears, an intense headache, and a tingling on the side of her face.
(Alleged China attack)
>Meanwhile, the roster of victims was growing ever longer. In June 2018, the U.S. State Department evacuated nearly a dozen people from Guangzhou, China, where American diplomats and trade representatives reported feeling symptoms eerily similar to those their colleagues had experienced in Cuba. One victim, Catherine Werner, said that her symptoms began in late 2017, just as Polymeropoulos’s had: a splitting headache, nausea, loss of balance. When her mother went to Guangzhou to help her, she, too, fell ill. Even Werner’s dogs were affected, her mother told NBC News. They began vomiting blood and avoiding the room where Werner and her mother heard the sounds and felt the symptoms start.
These two scenarios definitely did not adjust my confidence about any of this. The reported symptoms are indeed different. I just think it's interesting. It absolutely could be a red herring.
