Since Monday, Biscuit has coughed 1-3 times each morning straight after waking. He doesn't do it any other time of day and seems to be eating, drinking and perfectly well otherwise. Exercise doesn't make him cough either. He doesn't bring anything up. I goggled this and one suggestion was to check the bedding and bedding area for drafts, etc, which I will do today. I originally thought it was gagging and have taken him off Orijen completely but now I think he is coughing. I thought I'd give him 1 week before calling the vet as it could be something simple. Has anyone else ever experienced this?
