nervous about the car

Hi there.

I can clearly see how nervous your dog is when riding in the car.
My dog had a same problem. When we first adopted him at the age of 1.5 yrs (we never knew exactly how old he was nor any of his history since he was from a shelter) he hated/was very scared of riding in the car. I even had to get inside the car in the back seat with him and tie him on the leash otherwise he would come up to me to the driver seat when I was driving.

Just like your dog he had excessive slivering and panting. He was clearly nervous since he was not used to be in the car, I figured. Of course he threw up and even pooed in the car.

I don't know how long you have had your dog but if you just got him recently it is possible that your dog is simply not familiar with riding in the car, vibration, smell, instability, anything about driving. Or, he might have had bad experience riding in a car in his previous life, such as he was taken to a vet in a car (although all of my dogs LOVE vet visits many of dogs don't like them), or to a shelter, etc. However, it is very possible that he will get over it not so long.

What I would suggest is to give him a lot of opportunities to get familiar with riding in the car, very short trips but to fun places, such as dog parks, pet stores, just to a nearby park where you can park your car and take him for a nice walk, etc. This way your dog will not only get used to riding but also will associate car ride with something good/fun for him.

If you don't see any progress in, say a couple of weeks, you might want to consult with your vet. He might have some other medical problems. I also heard that there are herbal remedies to calm him down.

Hope your dog will get over it soon!
