The most common causes of gas in dogs include diet, parasites, and internal health problems. Because increased levels of gas can be caused by a number of things, there is no one answer for fixing the problem.
Dogs may suffer from gas from time to time. However repeated incidences of gas can be an uncomfortable condition for your dog, and these incidences can also create an unpleasant atmosphere that neither you nor your dog will appreciate. Fortunately there are steps that you can take to help prevent bouts of gas if your dog suffers from frequent episodes of flatulence.
