Funny... Same thing with me. Overloaded flight from BWI to MHT with a million preboarders and a damn dog that was barking and crying loudly all flight. To the point where folks were yelling at the owner to shut the dog up.

FA told the passenger to stuff the dog under the seat. Every time he did, the dog started screaming. It got very bumpy so the pilot had the FAs sit for the entire flight so the guy snuck the smelly, loud dog on his lap the entire flight.

I don't mind dogs on flights but when they bark for an hour, that's a little much.
