Travel with your dog survey

A recent survey by Petplan Pet Insurance reports that over half of the 3300 people surveyed travel with their dogs.

68.8 percent travel over 200 miles with their dogs for vacations.

97 percent travel by car.

56 percent have traveled by mobile home.

28 percent have traveled by train.  I found this interesting as Amtrak doesn’t accept pets on trains.  Does anyone have any ideas how these dogs traveled by train?  I would be very interested to hear.
