My dog has been dry heaving at about 3am for the last 2 nights for about an hour then again at 7. He hasn't thrown up. He still eats and plays all day though

Hello! Sometimes coughing sounds a lot like dry heaving, so it is possible that Otis might be coughing! If so, there are infectious coughs (such as kennel cough), that might be causing the trouble. Or, there could be something irritating his throat. GDV (gastric dilation/volvulus) is the classic cause of dry heaving, but since Otis is playing and eating, this is next to impossible! My recommendation would be, that if this continues, particularly if he is becoming lethargic or losing his appetite, he should ideally be checked by his vet! In the meantime, probably best to isolate him from other dogs, in case he has a contagious cough! Best of luck with Otis!
