Pets can travel by metrorail or subway in Washington DC, as long as they are locked in a secure vehicle. Service animals are also allowed. What do you think? Would you rather travel with your dog by train than by plane? We know this from the comments below. In addition, passengers should be aware that pets are not allowed on travel that requires train transfers. So, if you want to take your dog for a weekend, you must imperatively buy a direct trip. This information relates to pets, untrained service dogs, governed by the Americans with Disabilities Act and “allowed to go where the public is normally allowed to go.” Be prepared for a few size limits: Amtrak requires your pet carrier (along with your pet) to weigh less than 20 pounds. And before you ask, no, stacking six cats on top of them and dressing them in suits and ties won`t help you get around the system. To take your cat on a train, it must be in a suitable van, well ventilated and free of leaks. It should be placed under your seat or kept on your lap. Make sure you have plenty of water and are able to stop for relief breaks when the journey is long. To transport a pet between states, most states require the pet to have a Veterinary Inspection Certificate (CVI) that states that the pet is free of rabies and other infectious diseases.
Each state has different rules as to when the certificate must be obtained before entering a state, but the most common period is within 30 days before entry. . . .
