I have a 6 year old female black lab pointer mix who recently (since 11/16/13, so about a week) has been vomiting
, sometimes in the
even after work (about twice), but usually in the
middle of the night after 12am and before 5am. It's always yellow in color and foamy, with no food in it since it usually occurs about 3-4 hours after eating.
Everything else is normal, her activity level is the same, she still loves to eat, and her stool is firm.
