Depending on the diet, your dog can certainly go through "gassiness episodes" and create dog farts, and this could create "poor air quality" in his room or in the environment he stays in, and this would negatively affect the household. While the gas in the dog's fart is generally harmless, you and other people in the household would have to put up with this and the poor air quality it creates.
What causes this gassiness and dog farts? When a dog eats too fast, he will create a situation wherein air accumulates in his stomach. There are also certain foods that can bring about more gassiness. Dog food that is low quality, as well as foods such as cauliflower and beans can all create gassiness. You need to divide your beloved dog's daily ration and give him smaller portions instead; this will help prevent him from eating fast. Follow a strict daily feeding schedule while doing so.
A visit to your veterinary clinic McHenry IL can help pinpoint the cause of the issue.
