Question

Whats causing my rat terriers yellow vomit?

Answer 1

Our rat terrier just vomited a yellow/foamy bile. She was excited to see us and jumped up on a chair and the chair moved and she fell awkwardly causing her to freak out and yelp loudly.  Once she calmed down she vomited. We know she had not yet eaten her dinner (thus causing the bile).  We are hoping this is only due to the dog being in shock after the fall.
