Dog and I have traveled to over 45 countries together. It's not as difficult as you'd expect.

After rescuing Elko, a 2-year-old Jack Russell–Chihuahua mix, three years ago, the author says the pair have traveled to more than 45 countries across three continents. The dog’s small size—about 11 pounds—lets him fly in his carrier beside the passenger on every trip, the writer reports. The key is planning: calling airlines to reserve limited spots for in-cabin pets, often with fees ranging from $75 to $200, and checking destination paperwork. The author cites different requirements by country, including rabies certificates and sometimes tapeworm medication. A past UK document error nearly triggered a quarantine hold but was resolved quickly at the border.
