Then, to make matters worse the next day he goes back into the dreaded car. This time he visits a place full of shiny stainless steel that smells of disinfectant and animal fear. A stranger in a white coat sticks a needle in him and then... back in the car again.
A few days down the line the puppy is old enough to go out for a walk. So you decide to take him to the dog park which is a short drive away. You put pup on the backseat, only to have him throw up and spend a miserable journey shaking and whining. His reaction was so bad that now you dread taking him in the car again.
What to do?
To get around this, you need to take your time getting the pup comfortable in a stationary car, and only then think about turning on the engine, then taking short trips to pleasant places.
That said, it is well worth the effort since the result will be a dog that happily jumps into the car in anticipation of a pleasant adventure, and is a rock solid traveler without a hint of motion sickness.
