PROBLEM CASES - HOW TO DESENSITIZE YOUR DOG TO CAR RIDES Dogs who become carsick must be exposed SLOWLY to riding in the car. Each step should take a week, and if the dog gets sick on a step, you need to back off to the previous step until he doesn't get sick.
1. Put the dog in the car. Have a toy to keep the dog's mind off the car, but don't let him get too rowdy.
2. Dog in the car, car started and running in driveway.
3. Dog in the car, car started. Back down the driveway and then move back up the driveway (IF the dog hasn't gotten sick on the way down!)
4. Dog in the car, take car around the block (shorten the trip for a week if even that is too much)
5. Dog in the car, take car to local convenience store and back home (or any place close but farther than around the block with a couple of starts and stops along the way).
6. Dog in the car, short trip (you decide the length based on how your dog is responding.
Dogs who get carsick will especially benefit from either a crate (especially the more enclosed plastic crates) or a seatbelt (check your local pet shop for dog seat belts). These will limit unsteady movements. Keep in mind, dogs don't always vomit when they are carsick. Some may just drool excessively or look wet around the mouth and may have a sick or queasy look in their eyes. Watch your dog for signs of carsickness and work with the steps above to make both of you feel better!
