without knowing more info..... I never heard of using the dramamine for yorkies (you may be able to Ill let the more experienced in this area handle that) but how does your baby ride in the car? I have heard that if you use one of those snug car seats for pups that it makes them feel secure and I use a thundershirt on Charlie when he rides in the car. it helps allot. Charlie is 6 and he is just now starting to enjoy riding in the car. you will get allot of help with this from YT. Good luck
