Collies are generally excellent car travelers, and their calm temperament makes road trips a viable and enjoyable option for families who want to include their dog in vacations and outings. The key to successful car travel with a Collie begins with proper restraint. A dog of this size should be secured in the vehicle using a crash-tested harness that attaches to the seat belt system, or confined in a crate that is large enough for the dog to stand, turn around, and lie down comfortably. Unrestrained dogs in moving vehicles pose a safety hazard to themselves and to human passengers in the event of a sudden stop or collision.
For Rough Collies, the abundant double coat creates additional considerations during car travel. The interior of a vehicle can heat up rapidly, even on moderately warm days, and a heavily coated dog is more susceptible to overheating than a short-coated breed. Ensure the air conditioning is running and directed toward the dog's area, and never leave a Collie unattended in a parked vehicle. Even with windows cracked, interior temperatures can reach dangerous levels within minutes. Smooth Collies are somewhat less vulnerable to heat but should receive the same precautions.
Planning regular stops is essential for long drives with a Collie. Every two to three hours, find a safe area where the dog can stretch its legs, relieve itself, and drink fresh water. Collies appreciate the opportunity to walk and sniff in new environments, and these breaks help prevent restlessness and anxiety during extended drives. Bring a portable water bowl, waste bags, and a leash rated for the dog's size and strength.
Motion sickness can affect some Collies, particularly puppies and dogs unaccustomed to car travel. Gradual desensitization, beginning with short trips and gradually increasing duration, is the most effective approach. Feeding the dog a light meal several hours before travel rather than immediately before departure can reduce nausea. For dogs with persistent motion sickness, consult a veterinarian about safe anti-nausea options, keeping in mind the MDR1 drug sensitivity common in the breed.
