For 3 weeks now my 5 month old english bulldog puppy coughs or dry heaves and sometimes throws up. It always happens in the morning. Sometimes at night but never during the day. If he does throw up it may contain a bit of his food, or just foamy bile. Ive been to two vets and both ruled out anything serious but couldnt tell me what it was. It is on going and im very concerned. Can someone PLEASE tell me what it is?
I have a video of what he does, take a look http://youtu.be/YOgHoWDsQTk
