I usually consider whether the gas is bothering the dog or just me. If it’s just me I’m less concerned. Besides changing food again you should confirm if you are giving the correct amount as recommended on the package, consider if the dog is eating too rapidly or other things that could contribute to gas because the already mentioned issue of it simply not agreeing. Any gas caused solely by a change in diet I would expect to subside in a week or two after the switch.
