Well, sometimes dogs get so excited that the purge to calm down. It could be anxiety. Dogs get phobia just like people, and she could just really freak herself out about the car. Especially if she vomited in the car. If she seems fine after she throws up I wouldn't think much of it. (Are the cool down walks on the way to the car?)
Another thing, does Tillie get raw bones, or grasses? They are VERY good for their digestive systems...
I hope this helped and Tillie is fine :)
Vomited as usual was a bad choice of phrases.Three trips to the dog park=3 incidents of vomiting.
She does fine if we are around our home.She will play so hard, sometimes I intervene & make her stop.
We will cool off & take a short walk too relieve herself.
Thanks for all the input
She is a very healthy & happy companion.
It has been over a month since my original post & it has not happened since.
Thanks for all the replies
