Ugh the dog threw up in the car again! It is doubtful that anything is much more unpleasant than to have a dog get sick every time he is taken out in the car. Not only is it disgusting, annoying, and inconvenient to the owner, but it is upsetting to the dog as well. Desensitizing your dog to traveling in a car may take some work and some time, but it can be accomplished. Car sickness in dogs is a common problem. It is more common in puppies possibly due to not having the parts of their inner ear, the vestibular system responsible for maintaining balance, being fully developed. If this is the case, then in time, your puppy will outgrow motion or car sickness as they get older. If your dog is older and experiencing car sickness problems, there are ways to assist him.
