Bella used to be fine when she was very young, but since she was about 4 months old (she is 10 1/2 months now) she shakes, so badly that sometimes I think she is just going to fall apart. She also pants with her tongue hanging out and giving her water doesn't help. After awhile she goes to sleep and does pretty good. But the first half hour to 1 hour is bad. I think it is anxiety with her. But she doesn't vomit thank god. At least not yet.
