Shivon has had anxiety in the car for a couple of months now... at night and on the highway. She starts to shake, and curls up into a ball. When she gets more anxious she starts to pant. I have been thinking about ways I can help her anxiety, without giving her medication or drugs. Driving to agility takes about 30 minutes without taking the highway (at night), and her anxiety gets worse on the highway. I have recently discovered this, http://www.thundershirt.com/ the thundershirt. My agility trainer also reccommended it to me. So, what do you think?? Is the thundershirt worth using??? What's your opinion??
