when chili was a pup we travelled cross country thousands of miles and had 1 minor problem with a hotel room and curtains...but now chili is almost 5 and planning another long, long car trip. when chili was a pup he slept entire time in car in back seat uncrated. now that he is adult, he has a problem travelling unless i crate and cover crate with blanket. I tried benedryl and melatonin...neither work. I dont want to crate chile from west coast to east coast in car. I have a small suv/lexus nx....so I plan on either folding back seats down and tie down harness or maybe gate from trunk to back seats....chili's problem is that he has to be in front seat....this wont happen. long multiple day trip one way and looking for opinions...was going to fly til I realized his crate too big in most / all rental cars.
