Can I take a dog on a train to Da Nang, and are pets allowed inside sleeper compartments?

For a dog weighing about 15 kg, overland travel to Da Nang from Nha Trang or Hanoi—by train or private transfer—is being considered to avoid two flights with a connection.

On a Ho Chi Minh City–Da Nang train, attendants reportedly did not allow a dog into a fully booked sleeper compartment. The dog was only permitted in a carrier in the vestibule, reportedly under new rules.

As practice may differ between trains, confirm with the operator before paying whether the dog may stay in the compartment, whether a carrier is required, and where the pet must be kept during the journey.
