Sounds like this is a common problem! Raleigh has terrible gas… it’s room clearing. I wish it was the “silent but deadly type” but it isn’t.
I tried “Doggie Gas-X” but found no results.
My vet recommended plain yogurt. We’ve tried that and it seems to work. It doesn’t eliminate it fully but it gives her and us some relief. I always make a little bowl of it for her at night. I’ve also tried the flavors and it works the same. She loves it! She thinks it’s a treat and laps it up in a few seconds.
