13 week old threw up stomach bile.
At 5:00 this morning my little dude threw up, 2 different times, a small amount of stomach bile. It didn't have anything else in it that I could see, just a yellowish/slightly green liquid. He seems to be acting normal and still had his appetite, but we will be keeping a close eye on him...
Is this normal for puppies to do time to time or am I justified in being a little alarmed.
