There are a huge number of reasons this can happen. It can be infection, anatomic, disease or even a mass. And it can be anywhere from the nose to the diaphragm. You would need to bring your pup to the vet for an examination to start looking for the root cause and then help you find a treatment plan.
Six is about when my friend’s chi presented symptoms of dilated cardiomyopathy, which is a heart condition. I would encourage you to get your dog seen ASAP…and get on the horn with a cardiologist.
