Charlie, my one year old chi, did reverse sneezes every day since I got him. About 2 or 3 months ago I switched his food from a mixture of kibble and canned to Ziwipeak. I ran out of Ziwipeak and didn't order some more in time so I put both dogs back on the kibble and canned three days ago. Charlie started reverse sneezing again yesterday. Anybody else seen a correlation between the sneezing and diet or do you think it's just a coincidence?
