When I first adopted Cody he would throw up in the car, OMG. I was devastated because my girls who I raised from 8 week old pups were just about raised in cars. They went everywhere with me. When I had my girls there were no Pet Smart, PetCo, Pet Supplies in my are in NY. In Pa. where we camped there was, I once took the 3 into Pet Supplies, I needed an E collar for the youngest. All 3 went ballistic, trying to climb out of the cart. So out we went. I have to assume it was all the smells of the store, they reacted like they did at the vets office. So, I never went into one of those stores again.
Now I have a dog that gets sick in the car. The only time he was in it was for vet visits and groomer, both terrifying places for him.
Shortly after adopting him I stumbled onto Yorkie Talk and read about booster seats. I knew he needed a booster seat that was elevated off the seat so he couldn't feel the road bumps. I purchased one in Pet Supplies and prayed this would work and eliminate his sickness, (the vet did give me pills to give to him one hour before he went in to the car, I didn't want to give my dog a pill to just take a joy ride with me, also many of my outings are spontaneous so a pill wouldn't work).
That was 8 years ago. The first time I used it I had to carry him to the car, he hated the car. I put him in and buckled him up. I live on a mountain, a lot of S turns. I went down the mountain very slow, usually he would vomit before reaching the main road, well we got to the main road and he didn't get sick. I drove slower, took any turns slower. No vomit. One round trip and no car sickness.
The second time we had to go in the car he didn't fight me, in the booster he goes, down the mountain and into town. He is sitting in his booster seat like a king on his throne. He was able to see out of the window, and he was loving it. That was 8 years ago, he has never gotten car sick since, so booster seats do work for car sickness. And, when they are able to see out of the window also helps.
