According to most river cruise lines and travel agencies, the answer is generally no - it’s not possible or recommended to bring dogs on a river cruise. This is mainly for safety reasons and due to health concerns.
Most river cruise ships have limited space and facilities that are designed specifically for human travelers, making it difficult to accommodate pets. Additionally, river cruises often visit areas with unique ecosystems and wildlife, which could be disturbed if dogs were allowed onboard or ashore.
Some cruise lines may offer special pet-friendly options on their ocean-going vessels, but these are usually carefully regulated and require advance planning. River cruising is quite different from ocean cruising, so it’s best to check with the specific river cruise line directly for any potential exceptions or accommodations related to pets.
Keep in mind that some travel agencies specialize in dog-friendly excursions and vacations; they might offer alternative options like pet-sitting services while you’re away on your trip!
