Okay, Lucky seems to be vomiting almost every day. The vetrinarian checked for worms and the test just came back today negative. He has no worms, and he's up to date with his shots. I'm not sure what could be the cause of him vomiting. He only eats his dog food with occasional treats. He doesn't have any diarrhea either. What could this be? A friend of mine says that it's normal for a Yorkie to throw up often.. he said it's most likely due to running around and playing too much.. causing him to vomit. Sounds like bs to me.. some feedback would be appreciated.
