About 3 weeks ago, my 4 year old vizsla decided that she didn't want to go in the car!! She has always got into the boot of my freelander with no problem. She started shaking and pulling away. I finally got her in and she was fine whilst traveling. Returning from our walk, she jumped in no problem. This happened every day, so I started walking locally and just getting her into the boot with treats etc but not going anywhere. I did that for over a week and have been away for 5 days so she had almost 2 weeks with no car. I thought she might be ok when I tried again this week but she is just as bad, if not worse. Any ideas?????
