If your dog refuses to eat after experiencing car sickness, avoid forcing them. Instead, provide food and let them eat when they feel better. This condition usually lasts for a day or two. If your dog still isn't eating after two days, it's best to consult a veterinarian.

Car sickness in dogs can cause a range of discomforts. If your dog doesn't want to eat, don't force it. Simply leave the food in their bowl and let them eat when they are ready. This lack of appetite often lasts a day or two. However, if your dog is still not eating the second day after the car ride, it might indicate a more serious reaction to the car sickness or an underlying illness, and a visit to the vet for examination and treatment is recommended.
How to Overcome Car Sickness in Dogs
1. Before taking your dog on a car ride, ventilate the car by opening the windows to reduce any strong odors. If it's summer, turn on the air conditioning beforehand to lower the car's temperature. Dogs are sensitive to heat, and a hot car can distress them. So ensure that the car temperature is within a comfortable range for your dog!
2. Several hours before the car ride, avoid feeding your dog. It's best if they are on an empty stomach. Car rides can be bumpy and upsetting to their stomachs, and a full stomach can easily lead to car sickness and vomiting. Also, make sure your dog goes to the toilet before getting in the car, especially for long trips, as it can be quite difficult to stop on highways.
