OP here. I will try less table scraps and some yogurt. I definitely won't be giving them Chipotle!

don't ever give him the rest of your Chipotle, that will cause some evil gas

Maybe it's age. Co-worker has this problem.

I had this problem with a cat. Girl could clear a room. I started giving her a tablespoon of natural unflavored yogurt every day, and it cleared right up.

You can kill a dog with a thimble sized piece of my MIL's fruitcake.

Table scraps cause gas for my dog. She does best with hard dog food, such as Dog Chow. Science Diet and Iams also caused gas.

Two big dogs, no change in brand of dogfood, but it is getting really bad. They are getting more table scraps over the holidays, so maybe it's that, but if you've figured this out with diet changes or a brand of food that lessens this, please let me know!
