Ok I just wanted to make sure it wasnt a little pup that wasnt eating. The throwing up the yellow bile is usually nothing too worry about they will do that if they are hungry. The not eating is something to be concerned about because that can be an indicator that something is wrong. It sounds like he did eat yesterday for you but not today. I wuld give it a day or two and if it continues I would make a vet appt. If he starts vomiting his food make a vet appointment |
