The Bouvier des Flandres is a large, heavy dog, and car travel with the breed requires thoughtful preparation to ensure the safety and comfort of both the dog and the vehicle's occupants. The most important consideration is restraint. An unrestrained Bouvier in a moving vehicle poses a serious safety risk in the event of a sudden stop or collision. A dog weighing 80 to 110 pounds becomes a dangerous projectile in a crash, and even routine braking can cause an unsecured dog to slide or tumble.
For most Bouvier owners, the best solution is a sturdy, crash-tested crate sized for a large breed, secured in the cargo area of an SUV, wagon, or minivan. The crate should be large enough for the dog to stand, turn around, and lie down comfortably, but snug enough to prevent excessive movement during transit. Alternatively, a heavy-duty vehicle harness that attaches to the car's seatbelt system can be used, though harnesses should be selected carefully to ensure they are rated for the dog's weight and have been tested for crash performance.
Temperature management is another important factor. The Bouvier's thick double coat makes the breed prone to overheating, particularly in warm weather. Air conditioning should be running before the dog enters the vehicle, and direct sunlight on the dog should be minimized with window shades. Never leave a Bouvier unattended in a parked car, even for short periods, as interior temperatures can rise to dangerous levels within minutes.
For longer road trips, plan regular stops every two to three hours to allow the dog to stretch, relieve itself, and drink water. Bring a portable water bowl, a supply of fresh water, and familiar items such as a favorite blanket or toy to help the dog feel at ease. Feeding should be kept light before and during travel to reduce the risk of motion sickness, which some Bouviers experience, particularly as puppies.
