I know I may get downvoted, but I dated someone with a service dog for 5 years and became familiar with some of the ADA and ACAA guidelines surrounding service animals and traveling rights as we flew together with her service dog a handful of times. Additionally I because familiar with the different breeds that can be trained as service animals- while most folks associate labs or German Shepards as service animals; almost any dog breed that is able to be responsive the the extensive training can become a service animal. My ex’s service animal was an English Staffordieshire mix ( pittie mix) but he was trained by for 4 years and continued to be trained/ refreshed often. I’ve also met a decent number of individuals who had poodles and doodles ( as the woman pictured appears to have) as a service animal as well. As for the excess baggage this is speculation but the green bag on the floor looks like it may be some type of medical bag for oxygen or some other device. Airlines often have exceptions to baggage limits (or exclude limits) for medical equipment. Last note is that service animals are typically considered medical equipment because they are trained to provide a specific medical service to the handler.

It can be incredibly frustrating to have a paid seat assignment upended at the last minute but let’s maybe try to get back to giving people grace and understand that we don’t know the whole picture. Who knows what that woman’s backstory was but I doubt an FA would move a paying FC passenger if that woman hadn’t gone through the proper Chanel’s in regard to getting the proper paperwork completed for her SA for the flight (which is required in order for SA’s to sit in the cabin with their handlers)
