thanks for everybody's great advice!
he finally stopped puking and drooling!
he even jumps in the car himself!!

great to hear you've solved the problem and you can now enjoy your dog as it should be! :)

yey, glad to hear he's better with the car rides!

I had a german shepherd when I was a kid and i'd LOVE to have one again, when my living situation allows. They're fabulous dogs!
