If Oreo is continually vomiting I would recommend taking him to a veterinarian. Puppies can get sick and decline quickly. This may not be a virus but it can be something he ate. The veterinarian will be able to provide nutritional support and rehydrate Oreo. They can also give medication to stop him from vomiting. I hope Oreo feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach.
