The Brittany's medium size and adaptable temperament make it a naturally good car traveler, but proper preparation is still essential for safe and comfortable road trips. A crash-tested crate or secured travel kennel is the safest way to transport a Brittany in a vehicle. The crate should be large enough for the dog to stand, turn around, and lie down comfortably, and it should be anchored to the vehicle to prevent shifting during sudden stops or turns. For SUVs and station wagons, a cargo-area crate is ideal and keeps the dog contained without taking up passenger seating.
For owners who prefer not to use a crate, a dog-specific seatbelt harness provides an alternative restraint method. These harnesses attach to the vehicle's seatbelt system and limit the dog's movement in the event of a collision or hard braking. Unrestrained dogs in moving vehicles pose a safety risk to themselves and to passengers, and many jurisdictions now require some form of pet restraint during vehicle travel.
Brittanys are active dogs that benefit from regular breaks during long drives. Planning stops every two to three hours allows the dog to stretch, relieve itself, and drink water. A collapsible water bowl and a supply of fresh water should be part of every road trip kit, along with waste bags and a spare leash. Exercising the dog before departure can help reduce restlessness during the drive and encourage the dog to settle in the vehicle.
Never leave a Brittany unattended in a parked vehicle, particularly in warm weather. Temperatures inside a closed car can rise to dangerous levels within minutes, even on moderately warm days. If stops are necessary, one member of the travel party should remain with the dog, or the dog should be brought along. Many states have enacted laws addressing animals left in hot vehicles, and penalties can include fines and criminal charges.
