Our havanese, Ashi, for the last three days, immediately after eating throws it back up in about 4 different times. Nothing has changed recently (except in March the loss of her big bullie brother). Same food, Blue Buffalo chicken. vet said to give her a pepcid a/c 10 mg (1/4 table) last night with nothing more to eat and another this morning and then feed her with some boiled white rice added to her food 30 minutes after the pepcid. It has stayed down so far. Other than this, she is acting just fine and normal.
