Amber is a bit better now. We still ride in a car with her on someone lap. She ignores all treats - still too much busy being afraid.
As a progress - I was cleaning car from a snow in the morning - she was next to me and not trying to run away or hide. I didn't turn car on. It helped.
When we going to a class last Sunday - my son got in a car and then put blanket over his lap and Amber just jumped in to his lap. Again - car was off. We are getting better. Thanks to everyone for help.
I had friends over for a weekend and she pointed to me very interesting fact – my puppy is like a child who is 3 years old! I remember my kids being three – running around, trying to get my attention, making mess in a house. Funny!
