I have a problem that I've never had before in all my years of dog ownership. My wife and I adopted a collie puppy from the animal shelter a few months ago. Every time she rides in a car she pukes. She is 6 for 6 so far with the latest episode being today. We thought she might grow out of it and I guess she still could but I feel so sorry for her. She starts drooling about a half mile from home and will usually goes about 10 miles drooling and then yaaaaack! Anybody else have this problem and if so what did you do about it? Meds?
