We're getting ready to take off for Utah in a couple days in a car. Some of you know that Ma'ii is TERRIBLE in cars. We've never really been able to really figure out just what the cause is for this. He doesn't seem afraid, just really really excited. No matter how much we've worked with him, how much time we've invested in dog trainers to work with him, absolutely NOTHING has been able to work. We finally caved and consulted our vet about this, and she prescribed us a sedative called acepromazine. I've never used it before, and I was wondering if anyone here has, and if so did it actually work (lol)? Were there any negative side effects?
