My partner and I are planning an epic road trip across Europe next summer, and we absolutely can't leave our Golden Retriever, Max, behind! We've heard that traveling with pets can be quite complex, with varying regulations for different countries regarding pet passports, vaccinations, breed restrictions, and even public transport access. We're looking for advice from fellow travelers who have successfully navigated Europe with their dogs or other pets. What are the essential things to consider before we go, and what are some common pitfalls to avoid?
