Motion Sickness in Dogs

Motion sickness results in nausea, excessive drooling, vomiting, and occasionally other signs such as poor appetite for several hours after the motion sickness event. Animals may yawn, whine, show signs of uneasiness or apprehension, or have diarrhea. Motion sickness is usually seen during travel by land, sea, or air, and signs usually disappear when the motion of the vehicle ceases.

The principal cause of motion sickness is due to stimulation of the sensory organ in the inner ear, which has connections to the vomiting center in the brain stem. Fear of the vehicle may be a contributing factor in dogs and cats, and signs may occur even in a vehicle that is not moving. This occurs if a dog has become preconditioned to illness associated with travel in a vehicle.

Motion sickness can be minimized with conditioning or medication in many dogs.

In some cases, motion sickness can beĀ overcome by conditioning the animal to travel.

These medications can be obtained from your veterinarian and include tranquilizers, sedatives, and products to decrease nausea and/or vomiting.
