[YEA] My 12 year old dog has had an intermittant cough for some months now. It may not be a cough but an irritated throat (which is what the vet saw). Every so often he would get up from his bed making a sound as though something were stuck in his throat. This happened several times a day. I solved this problem by adding 2 drops of food grade hydrogen peroxide to his water bowl. This choking/cough stopped within a day. If I forget it comes back the next day.
