My dog throws up when we go anywhere in the car. A. Dogs commonly get motion sickness while riding in cars.
Nausea is usually the cause and excitement adds to the intensity of it.
Taking your dog for frequent short car trips tends to get him over the excitement of being in a car and will put him in a calmer frame of mind. Instead of just trips to the vet, the groomer or the kennel, take your pet out to pick up a gallon of milk, the newspaper or on whatever errands you may be running. This should be given to your dog by mouth one hour prior to departure, and the dose depends on your pet's weight. Ask your veterinarian how much to give. Your vet can supply stronger medications, such as acepromazine which has the additional effect of sedation.
