Hi everyone, I have a 4 month old Doberman puppy who for the past few nights has had yellow bile like vomit in the middle of the night. It seems to be getting worse, last night multiple times. he normally eats 3x/day (last at 6P). Today he started vomiting his meals. He has had normal poops. Activity normal until today. seems more tired but thought maybe due to being up all night vomiting. urine ok, Tummy not bloated. Eats the grass and occasionally a chlorox wipe or laundry sheet if I can't catch him. Any ideas. Thought may be just stomach acid (previous posts) and was going to alter diet and try to give him something closer to bed time but throwing up food today is new.
