He's been off his food a bit all week but we've recently changed foods so thought it might be that. However this morning when I came down his breathing was really raspy and then he had a honking cough. This went on for maybe 5 mins but then nothing since. My understanding of kennel cough is that it goes on and on and wouldn't have stopped after a few mins? Going to ring the vets when they open but don't know if I'm over reacting!
