For a walk, you need to purchase a leash or tape measure that will help control the dog’s behavior in case of danger. For travel and trips to the veterinarian, a carrier bag and a closed container are suitable, and, according to the breeders, the pets themselves prefer the first option. Chihuahuas can get nauseous in transport, so be sure to take motion sickness tablets with you, as well as a small container of drinking water. Pampers and bag/container liner will come in handy on long journeys (plane, train).
