You know, I am NOT a dog person but service animals are always impeccably behaved and I would have had no issue with that dog underneath my feet for a flight. The yippee ones that don't seem to actually sit in their bags and bark throughout the flight I have a real issue with (but off topic)
The fact that no accommodations were made, that US seems to be standing by their clearly sham of a story instead of apologizing is ridiculous. We've all seen service animals and I do not believe the dog was "unable to be controlled". The mere fact that all the passengers threw a fit as well is very, very telling, even though none of us know the true story.
