Still though we know how much room there is not on these airlines. They should have paid for the dog to have his own seat not crowd other passengers. I understand this man’s complaint. In the future the airlines need to force this if they are not going to give more legroom, which we all know they are not.
Dog is a female and their weight is 110-140 pounds. Slept the whole flight. Hid under the seat after being punched so hard to believe too big. They had 4 seats so the dog was probably on the floor under 2 of them.
I am very sympathetic to those with true service animals - hearing, sight, intact strong bones - things we take for granted but if we were to lose them how much of our lives would be changed.
