[Zanders' mom]

Hi, I had switched Zander to Natures Variety and he started this reverse sneezing, at the time I didn't link it to the food so I panicked took him to the vet and they were very calm about it, yes he has allergies, it happens in dogs, blah, blah. They wanted to put him on allergy meds, but I am one that likes to get to the bottom of the problem not just cover it up with meds. So I got on the computer, researched reverse sneezing, causes, etc. then looked up the ingredients in the food he was eating, since that was the only thing that had changed, took him off of the food and I have not seen reverse sneezing again. Interestingly I had given him this food when he was younger and did not have this reaction. Many ailments in our pups can be traced back to ingredients in the foods they eat.
Good luck.
