OK....Bailey is very PG and up to this point she seems to have been in great health. Today she has "thrown up" 3 times and it's this watery, pinkish stuff. The last time she did it, it looked like it had tiny (and I mean really tiny) specks of red in it. She seems to be acting normally, is not in any distress and otherwise is eating and drinking well. Any thoughts as to what this is?
