LOL my GS is so anxious and excitable that I took several years to totally condition her to car rides. She LOVED the car - so much that the excitement + car motion made her sick. As with all puppies I took her lots of trips to acclimate her and I’d do everything gently, but it was several years before absolutely no more vomits. She would be so happy and giddy while riding that she’d throw up! LOL (I.e., neither just a ride nor just excitement makes her vomit - had to be a combo!)
I have been lucky, of all the dogs I have had in my 73 years, none were vomiters. Beinging a nurse the only thing I had to do in the hospital that grossed me out was hold the emieis basin for someone to vomit into....couldn’t even watch them or I’d throw up along with the patient...And believe me I did a lot of things non-medical people would think was gross. Didn’t bother me in the least
