Ddog is travel sick in a completely hit and miss kind of a fashion. We can do a 5 minute journey and he throws up, an hour long journey and he is fine or vice versa. It doesnt matter about length of time after eating or anything like that there is literally no pattern. Sometimes he is sick sometimes he isnt. We are doing a 2 hr journey at Christmas (we will stop for a quick walk in the middle) and could really do without him being sivk as the car will ne full or kids and presents and things. He travels in between the kids on the backseat. I've read that dogs can have human travel.sickness tablets but which ones and what dosage? Does anyone know?
