I have a one year old pup who is miserable while in the truck. He just sits there, head down and drools. He has stopped throwing up a few months ago and I thought he would get over it, but he's not. Anyone have this problem? If he sees me with a gun heading for the truck, he goes in the garage and lays down. I really want him excited about going hunting. Boatrides don't bother him at all. But if I put him in the bed of the truck, he tries to bail out, even tied down. Once I get moving, he lays down an drools.
