Really...just a inconsiderate dog owner.
Besides, the dog should be in a cage on a flight.
Even a blind person does not need a service dog on a 4 hour flight, just to sit in the seat. The dog does not know where the restroom is if owner needs to go.
My guess is the crew had enough disgust after picking up the first load of dump. Lacking proper equipment such as pooper scooper, they decided to make a unscheduled stop, I do not blame them.
That’s just a stupid statement. Do you think the guide dog has a GPS to tell him/her where they are going? The guide dog doesn’t know where to go, the blind person tells them where to go. (left, right, etc) So the guide dog would just lead the blind person and the blind one would tell him the commands.
