To chime in on the carsickness thread, thankfully, my DS puppy doesn't experience motion sickness, nor does my older dog, but I've had two dogs over the years who did.
One, my childhood GSD, Heidi, was carsick AND terrified of the car, she eventually outgrew the carsickness, but still hated the car even after she would no longer vomit... Poor girl would tremble and shake and drool all over herself and do anything to avoid going near it. My mom finally made the connection that, duh, the only time she was ever in the car was to go for a trip to the vet or some other necessary car ride... Because of the sickness and her misery, we'd avoided making her go in the car unless necessary, but then, she had only negative associations with it.
We started doing super short, fun rides.
Even if you just drive a few doors down, park in a neighbor's driveway (ask them, first,

) and then go for a walk. Start with super short trips, and make car rides always lead to something enjoyable. Then you can gradually go for further destinations, still to fun activities/destinations... And over time, they should start to change their impression of what getting in the car represents. I don't recommend treats, though, as if they are still prone to physical illness, having stuff in their belly just gives them more to vomit up.
My second carsick dog was my rottie/pit rescue, Cedar. He was 10-11 months old when I adopted him, and while he liked the car just fine, he'd always yerk while riding. He actually, on his own, made a connection between eating and getting sick while riding, and he would never accept treats when we were out and about. We'd go to a locally-owned Pet Supply store, (and all my dogs learn quickly that the people wearing the aprons are treat dispensers!) and they'd offer him a treat, he'd take it, out of politeness, and then as soon as they walked away to help someone else he'd spit it out on the floor and step away from it and my GSD Cory would happily gobble it on his behalf.
He eventually, too, outgrew his carsickness and if I fed him before we went somewhere, it wasn't a problem, but he never did change his mind about taking treats if he knew we were only somewhere temporary and would be going back to the car soon.
Most dogs, with experience and time, will develop out of the physical habit of being sick in a car, but until they have moved beyond it it's kinder to their bellies and your cleaning efforts if you make sure they aren't full of food before you do car rides.
If, for some reason, your dog ends up being one of the rare, rare dogs that never outgrow it, you can give them dramamine or a similar motion-sickness medicine to help when you know you need to travel. You can talk to your vet about options and dosages. This is rarely necessary, though, as most dogs will, with time and experience, get past the period of getting sick in cars.
